Usage: nomad eval-monitor [options] <evaluation>
Start an interactive monitoring session for an existing evaluation.
The monitor command periodically polls for information about the
provided evaluation, including status updates, new allocations,
updates to allocations, and failures. Status is printed in near
real-time to the terminal.
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.

The eval-monitor command is used to attach a log monitor to an existing
evaluation using its ID.

# 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>
```
An evaluation ID or prefix must be provided. If there is an exact match, the
the evaluation will be monitored. Otherwise, a list of matching evaluations and
information will be displayed.
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
<%= general_options_usage %>
## Status Options
* `-verbose`: Show full information.
## Examples

```
$ nomad eval-monitor 8262bc83

# Command: eval-status
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, ogs 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-status [options] <eval>
```
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

state (completed or failed). Exit code 0 is returned on successful
evaluation, and if there are no scheduling problems. If there are
