Agents list should indicate known problems with agents
Last modified: 2016-02-21 19:57:01 EST
The High Availability->Agents page should list whether there are any known problems with an agent.
For example if an older version of an agent tries to report, and it's auto-update fails (e.g. can't write to it's own directory), then that information should be available in the list.
Essentially, a JON administrator or manager should be able to review the state of all agents within a JON system. This would make it easy to identify if an agent is off-line or unable to communicate to the JON server for one reason or another. Some use-cases:
- What JON Agents are simply not running? (this can currently be obtained by agent availability)
- What JON Agents failed to auto-upgrade after the new version of JON server was installed?
- What JON Agents can not communicate with the JON server due to an incorrect end-point address or network communications error?
- What JON Agents are currently running and reporting to/accepting commands from the JON server?
Obviously, in some instances, we will not know why a JON agent is unavailable but in some instances we do know. Like version mismatch, talk-back on initial registration, agent reported itself as going down, agent's resources have been backfilled, etc.
