[jira] [Created] (TC-175) Traffic Monitor 2.0 doesn't remove OFFLINEd peers

Robert Butts created TC-175:
-------------------------------

             Summary: Traffic Monitor 2.0 doesn't remove OFFLINEd peers
                 Key: TC-175
                 URL: https://issues.apache.org/jira/browse/TC-175
             Project: Traffic Control
          Issue Type: Bug
          Components: Traffic Monitor (golang)
    Affects Versions: 2.0.0
         Environment: Any
            Reporter: Robert Butts
            Priority: Critical


If a Traffic Monitor is ONLINE in Traffic Ops, and thus in the peers data of other Traffic Monitors, and then changed to OFFLINE, other Golang Traffic Monitors stop polling, but continue to mark that peer as available, thus 'freezing' the availability of all their caches.

Because peer statuses are optimistic, all caches which were marked 'available' by that OFFLINEd monitor are then permanently available in all other monitors' `/publish/CrStates`.
