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.
