[jira] [Created] (MESOS-7100) Missing AGENT_REMOVED event in event stream

Haralds Ulmanis created MESOS-7100:
--------------------------------------

             Summary: Missing AGENT_REMOVED event in event stream
                 Key: MESOS-7100
                 URL: https://issues.apache.org/jira/browse/MESOS-7100
             Project: Mesos
          Issue Type: Bug
          Components: HTTP API
    Affects Versions: 1.1.0
            Reporter: Haralds Ulmanis
            Priority: Minor


I'm playing with event stream via HTTP endpoints.
So - i got all events - SUBSCRIBED, TASK_ADDED, TASK_UPDATED, AGENT_ADDED except AGENT_REMOVED.

What i do:
Just stop agent or terminate server(if cloud).

What i expect: 
Once it disappear from agent list (in mesos UI) to get event AGENT_REMOVED.

Not sure about internals, maybe that is not correct event and agents got removed after some period, if they do not come up. But in general some event to indicate that agent went offline and not available would be good.

If AGENT_REMOVED and AGENT_ADDED is kinda one-time events .. maybe something like: AGENT_CONNECTED/RECONNECTED, AGENT_LEAVE events would be great.
