Ken Giusti closed QPID-2841.
----------------------------
Resolution: Fixed
Set the TTL value in agent heartbeat messages to 2 times the agent heartbeat
interval. That should be enough to guarantee that at least one valid heartbeat
remains available at all times.
> QMF: set TTL on agent heartbeat messages
> ----------------------------------------

> Key: QPID-2841
> URL: https://issues.apache.org/jira/browse/QPID-2841
> Project: Qpid
> Issue Type: Improvement
> Components: Qpid Managment Framework
> Environment: all
> Reporter: Ken Giusti
> Assignee: Ken Giusti
>
> Heartbeats are issued periodically by QMF agents. Each heartbeat is
> stateless - there is no information loss if a heartbeat is dropped or ignored
> by the client. While performance testing, it was discovered that multiple
> heartbeats will queue up should a console be unable to consume them fast
> enough. Most of these heartbeats are stale: the agent has issue a new
> heartbeat(s) since the older heartbeat was queued. Processing these "stale"
> heartbeats is useless.
> By setting the TTL in heartbeat messages, stale heartbeats will be discarded
> by the broker instead of being sent to the console.
