* debug: remove the CLI check for debug_enabled
The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.
Also:
- fix the API client to return errors on non-200 status codes for debug
endpoints
- improve the failure messages when pprof data can not be collected

* remove parallel test runs
parallel runs create a race condition that fail the debug tests
* snapshot the timestamp at the beginning of the capture
- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist
* Revert "snapshot the timestamp at the beginning of the capture"
This reverts commit c2d03346
* Refactor captureDynamic to extract capture logic for each item in a different func
* snapshot the timestamp at the beginning of the capture
- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist
* Revert "snapshot the timestamp at the beginning of the capture"
This reverts commit c2d03346
* Refactor captureDynamic to extract capture logic for each item in a different func
* extract wait group outside the go routine to avoid a race condition
* capture pprof in a separate go routine
* perform a single capture for pprof data for the whole duration
* add missing vendor dependency
* add a change log and fix documentation to reflect the change
* create function for timestamp dir creation and simplify error handling
* use error groups and ticker to simplify interval capture loop
* Logs, profile and traces are captured for the full duration. Metrics, Heap and Go routines are captured every interval
* refactor Logs capture routine and add log capture specific test
* improve error reporting when log test fail
* change test duration to 1s
* make time parsing in log line more robust
* refactor log time format in a const
* test on log line empty the earliest possible and return

* Docs for Unix Domain Sockets
There are a number of cases where a user might wish to either 1)
expose a service through a Unix Domain Socket in the filesystem
('downstream') or 2) connect to an upstream service by a local unix
domain socket (upstream).
As of Consul (1.10-beta2) we've added new syntax and support to configure
the Envoy proxy to support this
To connect to a service via local Unix Domain Socket instead of a
port, add local_bind_socket_path and optionally local_bind_socket_mode
to the upstream config for a service:
upstreams = [
{
destination_name = "service-1"
local_bind_socket_path = "/tmp/socket_service_1"
local_bind_socket_mode = "0700"
...
}
...
]
This will cause Envoy to create a socket with the path and mode
provided, and connect that to service-1
The mode field is optional, and if omitted will use the default mode
for Envoy. This is not applicable for abstract sockets. See
https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/core/v3/address.proto#envoy-v3-api-msg-config-core-v3-pipe
for details
NOTE: These options conflict the local_bind_socket_port and
local_bind_socket_address options. We can bind to an port or we can
bind to a socket, but not both.
To expose a service listening on a Unix Domain socket to the service
mesh use either the 'socket_path' field in the service definition or the
'local_service_socket_path' field in the proxy definition. These
fields are analogous to the 'port' and 'service_port' fields in their
respective locations.
services {
name = "service-2"
socket_path = "/tmp/socket_service_2"
...
}
OR
proxy {
local_service_socket_path = "/tmp/socket_service_2"
...
}
There is no mode field since the service is expected to create the
socket it is listening on, not the Envoy proxy.
Again, the socket_path and local_service_socket_path fields conflict
with address/port and local_service_address/local_service_port
configuration entries.
Set up a simple service mesh with dummy services:
socat -d UNIX-LISTEN:/tmp/downstream.sock,fork UNIX-CONNECT:/tmp/upstream.sock
socat -v tcp-l:4444,fork exec:/bin/cat
services {
name = "sock_forwarder"
id = "sock_forwarder.1"
socket_path = "/tmp/downstream.sock"
connect {
sidecar_service {
proxy {
upstreams = [
{
destination_name = "echo-service"
local_bind_socket_path = "/tmp/upstream.sock"
config {
passive_health_check {
interval = "10s"
max_failures = 42
}
}
}
]
}
}
}
}
services {
name = "echo-service"
port = 4444
connect = { sidecar_service {} }
Kind = "ingress-gateway"
Name = "ingress-service"
Listeners = [
{
Port = 8080
Protocol = "tcp"
Services = [
{
Name = "sock_forwarder"
}
]
}
]

This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
Adds more clear indicators that the collections on the learn.hashicorp.com sites have specific instructions for single node deployments.

* Update glossary.mdx
1. Update header to the first section to "Consul Vocabulary" since these are the terms used in the context of Consul conversations.
2. Kept the header "Consul Glossary" since these are the terms useful for practitioners in the consul space.
3. Removed interlinking to terms on the same page.
