-## Overview
-
-Package `statsd` provides a Go [dogstatsd](http://docs.datadoghq.com/guides/dogstatsd/) client.  Dogstatsd extends Statsd, adding tags
-and histograms.
-
-## Get the code
-
-    $ go get github.com/DataDog/datadog-go/statsd
-
-## Usage
-
-```go
-// Create the client
-c, err := statsd.New("127.0.0.1:8125")
-if err != nil {
-    log.Fatal(err)
-}
-// Prefix every metric with the app name
-c.Namespace = "flubber."
-// Send the EC2 availability zone as a tag with every metric
-c.Tags = append(c.Tags, "us-east-1a")
-err = c.Gauge("request.duration", 1.2, nil, 1)
-```
-
-## Buffering Client
-
-Dogstatsd accepts packets with multiple statsd payloads in them.  Using the BufferingClient via `NewBufferingClient` will buffer up commands and send them when the buffer is reached or after 100msec.
-
-## Development
-
-Run the tests with:
-
-    $ go test
-
-## Documentation
-
-Please see: http://godoc.org/github.com/DataDog/datadog-go/statsd

-# How to Contribute
-
-## Getting Started
-
-- Fork the repository on GitHub
-- Read the [README](README.markdown) for build and test instructions
-- Play with the project, submit bugs, submit patches!
-
-## Contribution Flow
-
-This is a rough outline of what a contributor's workflow looks like:
-
-- Create a topic branch from where you want to base your work (usually master).
-- Make commits of logical units.
-- Make sure your commit messages are in the proper format (see below).
-- Push your changes to a topic branch in your fork of the repository.
-- Make sure the tests pass, and add any new tests as appropriate.
-- Submit a pull request to the original repository.
-
-Thanks for your contributions!
-
-### Format of the Commit Message
-
-We follow a rough convention for commit messages that is designed to answer two
-questions: what changed and why. The subject line should feature the what and
-the body of the commit should describe the why.
-
-```
-scripts: add the test-cluster command
-
-this uses tmux to setup a test cluster that you can easily kill and
-start for debugging.
-
-Fixes #38
-```
-
-The format can be described more formally as follows:
-
-```
-<subsystem>: <what changed>
-<BLANK LINE>
-<why this change was made>
-<BLANK LINE>
-<footer>
-```
-
-The first line is the subject and should be no longer than 70 characters, the
-second line is always blank, and other lines should be wrapped at 80 characters.
-This allows the message to be easier to read on GitHub as well as in various
-git tools.

-dbus
-----
-
-dbus is a simple library that implements native Go client bindings for the
-D-Bus message bus system.
-
-### Features
-
-* Complete native implementation of the D-Bus message protocol
-* Go-like API (channels for signals / asynchronous method calls, Goroutine-safe connections)
-* Subpackages that help with the introspection / property interfaces
-
-### Installation
-
-This packages requires Go 1.1. If you installed it and set up your GOPATH, just run:
-
-```
-go get github.com/godbus/dbus
-```
-
-If you want to use the subpackages, you can install them the same way.
-
-### Usage
-
-The complete package documentation and some simple examples are available at
-[godoc.org](http://godoc.org/github.com/godbus/dbus). Also, the
-[_examples](https://github.com/godbus/dbus/tree/master/_examples) directory
-gives a short overview over the basic usage. 
-
-#### Projects using godbus
-- [notify](https://github.com/esiqveland/notify) provides desktop notifications over dbus into a library.
-
-Please note that the API is considered unstable for now and may change without
-further notice.
-
-### License
-
-go.dbus is available under the Simplified BSD License; see LICENSE for the full
-text.
-
-Nearly all of the credit for this library goes to github.com/guelfey/go.dbus.

-/*
-Package dbus implements bindings to the D-Bus message bus system.
-
-To use the message bus API, you first need to connect to a bus (usually the
-session or system bus). The acquired connection then can be used to call methods
-on remote objects and emit or receive signals. Using the Export method, you can
-arrange D-Bus methods calls to be directly translated to method calls on a Go
-value.
-
-Conversion Rules
-
-For outgoing messages, Go types are automatically converted to the
-corresponding D-Bus types. The following types are directly encoded as their
-respective D-Bus equivalents:
-
-     Go type     | D-Bus type

-Slices and arrays encode as ARRAYs of their element type.
-
-Maps encode as DICTs, provided that their key type can be used as a key for
-a DICT.
-
-Structs other than Variant and Signature encode as a STRUCT containing their
-exported fields. Fields whose tags contain `dbus:"-"` and unexported fields will
-be skipped.
-
-Pointers encode as the value they're pointed to.
-
-Trying to encode any other type or a slice, map or struct containing an
-unsupported type will result in an InvalidTypeError.
-
-For incoming messages, the inverse of these rules are used, with the exception
-of STRUCTs. Incoming STRUCTS are represented as a slice of empty interfaces
-containing the struct fields in the correct order. The Store function can be
-used to convert such values to Go structs.
-
-Unix FD passing
-
-Handling Unix file descriptors deserves special mention. To use them, you should
-first check that they are supported on a connection by calling SupportsUnixFDs.
-If it returns true, all method of Connection will translate messages containing
-UnixFD's to messages that are accompanied by the given file descriptors with the
-UnixFD values being substituted by the correct indices. Similarily, the indices
-of incoming messages are automatically resolved. It shouldn't be necessary to use
-UnixFDIndex.

-Package proto converts data structures to and from the wire format of
-protocol buffers.  It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed by the enclosing message's name, or by the
-	enum's type name if it is a top-level enum. Enum types have a String
-	method, and a Enum method to assist in message construction.
-  - Nested messages, groups and enums have type names prefixed with the name of
-	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Getters are only generated for message and oneof fields.
-  - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
-	package example;
-
-	enum FOO { X = 17; }
-
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	  oneof union {
-	    int32 number = 6;
-	    string name = 7;

-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,

-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# Overview
-This is the [Prometheus](http://www.prometheus.io) telemetric
-instrumentation client [Go](http://golang.org) client library.  It
-enable authors to define process-space metrics for their servers and
-expose them through a web service interface for extraction,
-aggregation, and a whole slew of other post processing techniques.

-// The stock metrics provided by this package (like Gauge, Counter, Summary) are
-// also Collectors (which only ever collect one metric, namely itself). An
-// implementer of Collector may, however, collect multiple metrics in a
-// coordinated fashion and/or create metrics on the fly. Examples for collectors
-// already implemented in this library are the metric vectors (i.e. collection
-// of multiple instances of the same Metric but with different label values)

-	// consistency and uniqueness requirements described in the Desc
-	// documentation. (It is valid if one and the same Collector sends
-	// duplicate descriptors. Those duplicates are simply ignored. However,
-	// two different Collectors must not send duplicate descriptors.) This
-	// method idempotently sends the same descriptors throughout the
-	// lifetime of the Collector. If a Collector encounters an error while
-	// executing this method, it must send an invalid descriptor (created
-	// with NewInvalidDesc) to signal the error to the registry.

-	// metrics that share the same descriptor must differ in their variable
-	// label values. This method may be called concurrently and must

-// Package prometheus provides embeddable metric primitives for servers and
-// standardized exposition of telemetry through a web services interface.
-//
-// All exported functions and methods are safe to be used concurrently unless
-// specified otherwise.
-//
-// To expose metrics registered with the Prometheus registry, an HTTP server
-// needs to know about the Prometheus handler. The usual endpoint is "/metrics".
-//
-//     http.Handle("/metrics", prometheus.Handler())
-//
-// As a starting point a very basic usage example:
-//
-//    package main
-//
-//    import (
-//    	"net/http"
-//
-//    	"github.com/prometheus/client_golang/prometheus"
-//    )
-//
-//    var (
-//    	cpuTemp = prometheus.NewGauge(prometheus.GaugeOpts{
-//    		Name: "cpu_temperature_celsius",
-//    		Help: "Current temperature of the CPU.",
-//    	})
-//    	hdFailures = prometheus.NewCounter(prometheus.CounterOpts{
-//    		Name: "hd_errors_total",
-//    		Help: "Number of hard-disk errors.",
-//    	})
-//    )
-//
-//    func init() {
-//    	prometheus.MustRegister(cpuTemp)
-//    	prometheus.MustRegister(hdFailures)
-//    }
-//
-//    func main() {
-//    	cpuTemp.Set(65.3)
-//    	hdFailures.Inc()
-//
-//    	http.Handle("/metrics", prometheus.Handler())
-//    	http.ListenAndServe(":8080", nil)
-//    }
-//
-//
-// This is a complete program that exports two metrics, a Gauge and a Counter.
-// It also exports some stats about the HTTP usage of the /metrics
-// endpoint. (See the Handler function for more detail.)
-//
-// Two more advanced metric types are the Summary and Histogram.
-//
-// In addition to the fundamental metric types Gauge, Counter, Summary, and
-// Histogram, a very important part of the Prometheus data model is the
-// partitioning of samples along dimensions called labels, which results in
-// metric vectors. The fundamental types are GaugeVec, CounterVec, SummaryVec,
-// and HistogramVec.
-//
-// Those are all the parts needed for basic usage. Detailed documentation and
-// examples are provided below.
-//
-// Everything else this package offers is essentially for "power users" only. A
-// few pointers to "power user features":
-//
-// All the various ...Opts structs have a ConstLabels field for labels that
-// never change their value (which is only useful under special circumstances,
-// see documentation of the Opts type).
-//
-// The Untyped metric behaves like a Gauge, but signals the Prometheus server
-// not to assume anything about its type.
-//
-// Functions to fine-tune how the metric registry works: EnableCollectChecks,
-// PanicOnCollectError, Register, Unregister, SetMetricFamilyInjectionHook.
-//
-// For custom metric collection, there are two entry points: Custom Metric
-// implementations and custom Collector implementations. A Metric is the
-// fundamental unit in the Prometheus data model: a sample at a point in time
-// together with its meta-data (like its fully-qualified name and any number of
-// pairs of label name and label value) that knows how to marshal itself into a
-// data transfer object (aka DTO, implemented as a protocol buffer). A Collector
-// gets registered with the Prometheus registry and manages the collection of
-// one or more Metrics. Many parts of this package are building blocks for
-// Metrics and Collectors. Desc is the metric descriptor, actually used by all
-// metrics under the hood, and by Collectors to describe the Metrics to be
-// collected, but only to be dealt with by users if they implement their own
-// Metrics or Collectors. To create a Desc, the BuildFQName function will come
-// in handy. Other useful components for Metric and Collector implementation
-// include: LabelPairSorter to sort the DTO version of label pairs,
-// NewConstMetric and MustNewConstMetric to create "throw away" Metrics at
-// collection time, MetricVec to bundle custom Metrics into a metric vector
-// Collector, SelfCollector to make a custom Metric collect itself.
-//
-// A good example for a custom Collector is the ExpVarCollector included in this
-// package, which exports variables exported via the "expvar" package as
-// Prometheus metrics.

-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each

-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally

-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or

-          that such additional attribution notices cannot be construed
-          as modifying the License.

-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,

-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

   task transitions to the dead state. [Click
   here](/docs/jobspec/servicediscovery.html) to learn more about services.
 
+     * `Name`: Nomad automatically determines the name of a Task. By default the
+       name of a service is `$(job-name)-$(task-group)-$(task-name)`. Users can
+       explicitly name the service by specifying this option. If multiple
+       services are defined for a Task then only one task can have the default
+       name, all the services have to be explicitly named.  Users can add the
+       following to the service names: `${JOB}`, `${TASKGROUP}`, `${TASK}`,
+       `${BASE}`.  Nomad will replace them with the appropriate value of the
+       Job, Task Group, and Task names while registering the Job. `${BASE}`
+       expands to `${JOB}-${TASKGROUP}-${TASK}`.  Names must be adhere to
+       [RFC-1123 §2.1](https://tools.ietf.org/html/rfc1123#section-2) and are
+       limited to alphanumeric and hyphen characters (i.e. `[a-z0-9\-]`), and be
+       less than 64 characters in length.
+
+     * `Tags`: A list of tags associated with this Service. String interpolation
+       is supported in tags.
+
+     * `PortLabel`: `PortLabel` is optional and is used to associate the port
+       with the service.  If specified, the port label must match one defined in
+       the resources block.  This could be a label to either a dynamic or a
+       static port. If an incorrect port label is specified, Nomad doesn't
+       register the IP:Port with Consul.
+
+     * `Checks`: `Checks` is an array of check objects.A check object defines a
+       health check associated with the service. Nomad supports the `script`,
+       `http` and `tcp` Consul Checks. Script checks are not supported for the
+       qemu driver since the Nomad client doesn't have access to the file system
+       of a tasks using the Qemu driver.
+
+         * `Type`:  This indicates the check types supported by Nomad. Valid
+           options are currently `script`, `http` and `tcp`.
+
+         * `Name`: The name of the health check.
+
+         * `Interval`: This indicates the frequency of the health checks that
+           Consul will perform.
+
+         * `Timeout`: This indicates how long Consul will wait for a health
+           check query to succeed.
+
+         * `Path`:The path of the http endpoint which Consul will query to query
+           the health of a service if the type of the check is `http`. Nomad
+           will add the IP of the service and the port, users are only required
+           to add the relative URL of the health check endpoint.
+
+         * `Protocol`: This indicates the protocol for the http checks. Valid
+           options are `http` and `https`. We default it to `http`
+
+         * `Command`: This is the command that the Nomad client runs for doing
+           script based health check.
+
+         * `Args`: Additional arguments to the `command` for script based health
+           checks.
+
+
 *   `Env` - A map of key/value representing environment variables that
     will be passed along to the running process. Nomad variables are
     interpreted when set in the environment variable values. See the table of
