# Command: eval-monitor
|
|
|
|
The `eval-monitor` command is used to monitor an existing [evaluation](#).
|
|
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
|
|
|
|
```
|
|
nomad eval-monitor [options] <eval>
|
|
```
|
|
|
|
The eval-monitor command requires a single argument, specifying the
|
|
evaluation ID to monitor. 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.
