# `nomad eval status` command reference
|
|
|
|
The `eval status` command is used to display information about an existing
|
|
evaluation. In the case an evaluation could not place all the requested
|
|
allocations, this command can be used to determine the failure reasons.
|
|
|
|
Optionally, it can also be invoked in a monitor mode to track an outstanding
|
|
evaluation. In this mode, logs will be output describing state changes to the
|
|
evaluation or its associated allocations. The monitor will exit when the
|
|
evaluation reaches a terminal state.
|
|
|
|
## Usage
|
|
|
|
```plaintext
|
|
nomad eval status [options] <evaluation>
|
|
```
|
|
|
|
An evaluation ID or prefix must be provided. If there is an exact match, the
|
|
the status will be shown. Otherwise, a list of matching evaluations and
|
|
information will be displayed.
|
|
|
|
If the `-monitor` flag is passed, an interactive monitoring session will be
|
|
started in the terminal. It is safe to exit the monitor at any time using
|
|
ctrl+c. The command will exit when the given evaluation reaches a terminal
|
|
state (completed or failed). Exit code 0 is returned on successful
|
|
evaluation, and if there are no scheduling problems. If there are
|
|
job placement issues encountered (unsatisfiable constraints,
|
|
resource exhaustion, etc), then the exit code will be 2. Any other
|
|
errors, including client connection issues or internal errors, are
|
|
indicated by exit code 1.
|
|
|
|
## General options
|
|
|
|
@include 'general_options.mdx'
|
|
|
|
## Eval status options
|
|
|
|
- `-monitor`: Monitor an outstanding evaluation
|
|
- `-verbose`: Show full information.
|
|
- `-json` : Output a list of all evaluations in JSON format. This
|
|
behavior is deprecated and has been replaced by `nomad eval list
|
|
-json`. In Nomad 1.4.0 the behavior of this option will change to
|
|
output only the selected evaluation in JSON.
|
|
- `-t` : Format and display evaluation using a Go template.
|
|
- `-ui`: Open the evaluation in the browser.
|
|
|
|
## Examples
|
|
|
|
Show the status of an evaluation that has placement failures
|
|
|
|
```shell-session
|
|
$ nomad eval status 2ae0e6a5
|
|
ID = 2ae0e6a5
|
|
Status = complete
|
|
Status Description = complete
|
|
Type = service
|
|
TriggeredBy = job-register
|
|
Job ID = example
|
|
Namespace = default
|
|
Priority = 50
|
|
Placement Failures = true
|
|
|
|
==> Failed Placements
|
|
Task Group "cache" (failed to place 1 allocation):
|
|
* Class "foo" filtered 1 nodes
|
|
* Constraint "${attr.kernel.name} = windows" filtered 1 nodes
|
|
|
|
|
|
Evaluation "67493a64" waiting for additional capacity to place remainder
|
|
```
|
|
|
|
Monitor an existing evaluation
|
|
|
|
```shell-session
|
|
$ nomad eval status -monitor 8262bc83
|
|
==> Monitoring evaluation "8262bc83"
|
|
Allocation "bd6bd0de" created: node "6f299da5", group "group1"
|
|
Evaluation status changed: "pending" -> "complete"
|
|
==> Evaluation "8262bc83" finished with status "complete"
|
|
```
