As I understand them, these issues are usually caused because Zenoss thinks there should be a daemon or process running that no longer exists because the name changed. This is often caused when you rename the Zenoss server from, say, localhost to FQDN.
Zenoss doesn't as far as I know have persistent internal heartbeat objects. That is, zenoss doesn't have a list of what should be heartbeated hard coded somewhere. If it's received a heartbeat from something, it thinks it should again, and if it doesn't, it alerts. Clearing heartbeats often fixes this issue, as if the daemon is really gone or renamed, the old name won't send a heartbeat that then would stop coming causing the alerts. So that's why using clear all heartbeats often works, it sets Zenoss to assume there is *nothing* to heartbeat on, and only builds up the alerting lists as new heartbeats come in from daemons. What's probably happening is that something is causing heartbeats to be missed, perhaps an overloading of the heartbeating daemon? -- James Pulver Information Technology Area Supervisor LEPP Computer Group Cornell University captn63 wrote, On 1/23/2009 6:51 PM: > I was able to shut down Zenoss and manually clear the heartbeats out of the > MySql database.
