A node must first be registered with the servers before it will be visible in this output. ## Usage ```plaintext nomad node status [options] [node] ``` If no node ID is passed, then the command will enter "list mode" and dump a high-level list of all known nodes. This list output contains less information but is a good way to get a bird's-eye view of things. If there is an exact match based on the provided node ID or prefix, then that particular node will be queried, and detailed information will be displayed, including resource usage statistics. Otherwise, a list of matching nodes and information will be displayed. If running the command on a Nomad Client, the `-self` flag is useful to quickly access the status of the local node. If ACLs are enabled, this option requires a token with the 'node:read' capability. ## General Options @include 'general_options_no_namespace.mdx' ## Status Options - `-self`: Query the status of the local node. - `-stats`: Display detailed resource usage statistics. - `-allocs`: When a specific node is not being queried, shows the number of running allocations per node. - `-short`: Display short output. Used only when querying a single node. - `-verbose`: Show full information. - `-json` : Output the node in its JSON format. - `-t` : Format and display node using a Go template. ## Examples List view: ```shell-session $ nomad node status ID DC Name Class Drain Eligibility Status a72dfba2 dc1 node1 false eligible ready 1f3f03ea dc1 node2 false eligible ready ``` List view, with running allocations: ```shell-session $ nomad node status -allocs ID DC Name Class Drain Eligibility Status Running Allocs 4d2ba53b dc1 node1 false eligible ready 1 34dfba32 dc1 node2 false eligible ready 3 ``` Single-node view in short mode: ```shell-session $ nomad node status -short 1f3f03ea ID = c754da1f Name = nomad Class = DC = dc1 Drain = false Status = ready Uptime = 17h2m25s Allocations ID Eval ID Job ID Task Group Desired Status Client Status 0b8b9e37 8bf94335 example cache run running ``` Full output for a single node: ```shell-session $ nomad node status 1f3f03ea ID = c754da1f Name = nomad-server01 Class = DC = dc1 Drain = false Status = ready Uptime = 17h42m50s Drivers Driver Detected Healthy docker false false exec true true java true true qemu true true raw_exec true true rkt true true Node Events Time Subsystem Message 2018-03-29T17:24:42Z Driver: docker Driver docker is not detected 2018-03-29T17:23:42Z Cluster Node registered Allocated Resources CPU Memory Disk 500/2600 MHz 256 MiB/2.0 GiB 300 MiB/32 GiB Allocation Resource Utilization CPU Memory 430/2600 MHz 199 MiB/2.0 GiB Host Resource Utilization CPU Memory Disk 513/3000 MHz 551 MiB/2.4 GiB 4.2 GiB/52 GiB Allocations ID Eval ID Job ID Task Group Desired Status Client Status 7bff7214 b3a6b9d2 example cache run running ``` Using `-self` when on a Nomad Client: ```shell-session $ nomad node status -self ID = c754da1f Name = nomad-client01 Class = DC = dc1 Drain = false Status = ready Uptime = 17h7m41s Drivers Driver Detected Healthy docker false false exec true true java true true qemu true true raw_exec true true rkt true true Node Events Time Subsystem Message 2018-03-29T17:24:42Z Driver: docker Driver docker is not detected 2018-03-29T17:23:42Z Cluster Node registered Allocated Resources CPU Memory Disk 2500/2600 MHz 1.3 GiB/2.0 GiB 1.5 GiB/32 GiB Allocation Resource Utilization CPU Memory 2200/2600 MHz 1.7 GiB/2.0 GiB Host Resource Utilization CPU Memory Disk 2430/3000 MHz 1.8 GiB/2.4 GiB 6.5 GiB/40 GiB Allocations ID Eval ID Job ID Task Group Desired Status Client Status 0b8b9e37 8bf94335 example cache run running b206088c 8bf94335 example cache run running b82f58b6 8bf94335 example cache run running ed3665f5 8bf94335 example cache run running 24cfd201 8bf94335 example cache run running ``` You will note that in the above examples, the **Allocations** output contains columns labeled **Desired Status** and **Client status**. Desired Status represents the goal of the scheduler on the allocation with the following valid statuses: - _run_: The allocation should run - _stop_: The allocation should stop Client Status represents the emergent state of the allocation and include the following: - _pending_: The allocation is pending and will be running - _running_: The allocation is currently running - _complete_: The allocation was running and completed successfully - _failed_: The allocation was running and completed with a non-zero exit code - _lost_: The node that was running the allocation has failed or has been partitioned Using `-stats` to see detailed to resource usage information on the node: ```shell-session $ nomad node status -stats c754da1f ID = c754da1f Name = nomad-client01 Class = DC = dc1 Drain = false Status = ready Uptime = 17h7m41s Drivers Driver Detected Healthy docker false false exec true true java true true qemu true true raw_exec true true rkt true true Node Events Time Subsystem Message 2018-03-29T17:24:42Z Driver: docker Driver docker is not detected 2018-03-29T17:23:42Z Cluster Node registered Allocated Resources CPU Memory Disk 2500/2600 MHz 1.3 GiB/2.0 GiB 1.5 GiB/32 GiB Allocation Resource Utilization CPU Memory 2200/2600 MHz 1.7 GiB/2.0 GiB Host Resource Utilization CPU Memory Disk 2430/3000 MHz 1.8 GiB/2.4 GiB 3.9 GiB/40 GiB CPU Stats CPU = cpu0 User = 96.94% System = 1.02% Idle = 2.04% CPU = cpu1 User = 97.92% System = 2.08% Idle = 0.00% Memory Stats Total = 2.4 GiB Available = 612 MiB Used = 1.8 GiB Free = 312 MiB Disk Stats Device = /dev/mapper/ubuntu--14--vg-root MountPoint = / Size = 38 GiB Used = 3.9 GiB Available = 32 GiB Used Percent = 10.31% Inodes Percent = 3.85% Device = /dev/sda1 MountPoint = /boot Size = 235 MiB Used = 45 MiB Available = 178 MiB Used Percent = 19.17% Inodes Percent = 0.48% Allocations ID Eval ID Job ID Task Group Desired Status Client Status 0b8b9e37 8bf94335 example cache run running b206088c 8bf94335 example cache run running b82f58b6 8bf94335 example cache run running ed3665f5 8bf94335 example cache run running 24cfd201 8bf94335 example cache run running ``` To view verbose information about the node: ```shell-session $ nomad node status -verbose c754da1f ID = c754da1f-6337-b86d-47dc-2ef4c71aca14 Name = nomad Class = DC = dc1 Drain = false Status = ready Uptime = 17h7m41s Host Volumes Name ReadOnly Source CSI Volumes ID Name Plugin ID Schedulable Access Mode Mount Options 402f2c83 vol plug true single-node-writer Drivers Driver Detected Healthy Message Time docker false false Driver docker is not detected 2018-03-29T17:24:42Z exec true true 2018-03-29T17:23:42Z java true true 2018-03-29T17:23:41Z qemu true true 2018-03-29T17:23:41Z raw_exec true true 2018-03-29T17:23:42Z rkt true true 2018-03-29T17:23:42Z Node Events Time Subsystem Message Details 2018-03-29T17:24:42Z Driver: docker Driver docker is not detected driver: docker, 2018-03-29T17:23:42Z Cluster Node registered Allocated Resources CPU Memory Disk 2500/2600 MHz 1.3 GiB/2.0 GiB 1.5 GiB/32 GiB Allocation Resource Utilization CPU Memory 2200/2600 MHz 1.7 GiB/2.0 GiB Host Resource Utilization CPU Memory Disk 230/3000 MHz 121 MiB/2.4 GiB 6.5 GiB/40 GiB Allocations ID Eval ID Job ID Task Group Desired Status Client Status 3d743cff-8d57-18c3-2260-a41d3f6c5204 2fb686da-b2b0-f8c2-5d57-2be5600435bd example cache run complete Attributes arch = amd64 cpu.frequency = 1300.000000 cpu.modelname = Intel(R) Core(TM) M-5Y71 CPU @ 1.20GHz cpu.numcores = 2 cpu.totalcompute = 2600.000000 driver.docker = 1 driver.docker.version = 1.10.3 driver.exec = 1 driver.java = 1 driver.java.runtime = OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-0ubuntu0.14.04.2) driver.java.version = 1.7.0_95 driver.java.vm = OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode) driver.qemu = 1 driver.qemu.version = 2.0.0 driver.raw_exec = 1 driver.rkt = 1 driver.rkt.appc.version = 0.7.4 driver.rkt.version = 1.2.0 hostname = nomad kernel.name = linux kernel.version = 3.19.0-25-generic memory.totalbytes = 2094473216 nomad.revision = '270da7a60ccbf39eeeadc4064a59ca06bf9ac6fc+CHANGES' nomad.version = 0.3.2dev os.name = ubuntu os.version = 14.04 unique.cgroup.mountpoint = /sys/fs/cgroup unique.network.ip-address = 127.0.0.1 unique.storage.bytesfree = 36044333056 unique.storage.bytestotal = 41092214784 unique.storage.volume = /dev/mapper/ubuntu--14--vg-root ```
