Reset by vsphere ha. reason vmware tools heartbeat failure

Navigating through task and events for the VM in vCenter, I was seeing message similar to. I checked for HA settings related to VM monitoring on the cluster and did not see any aggressive value set there which might have caused the vm restart.

The VM monitoring settings were set at 30 secs for failure interval which means that if for continuous 30 seconds VM is unable to send any heartbeat to HA, a restart of VM will be performed.

Keep in mind that this is not related to host failure where all VM running on failed host is restarted on remaining nodes of the cluster. I started my investigation with checking hostd. Next was to check vmware. I observed following log entries for VM reset. On digging vmware. I killed the vmtoolsd process on it, left it alone, and HA rebooted it after a few minutes while also triggering the alert.

Using OpenFaaS and its vCente The recent release of vRealize Automation 8. The Windows based IaaS servers have been This is another strange problem that I experienced recently.

The cluster settings are overridden by setting those VM overrides. I found at the VMware documentation p8. To enable Application Monitoring, you must first obtain the appropriate SDK or be using an application that supports VMware Application Monitoring and use it to set up customized heartbeats for the applications you want to monitor.

If the heartbeats for an application are not received for a specified time, its virtual machine is restarted. The default monitoring in the Guest OS can be expanded further via Application HA and vCenter Hyperic product which with the help of special agents installed inside of each of the monitored VMs can trigger the application restart. In such a case not the whole VM is restarted, but only the monitored application which failed.

It's also possible to monitor Applications through LogInsight product with help of Microsoft Content Pack which in it's latest version can monitor Windows and Linux VMs through a small, lightweight agents. The Microsoft Windows Operating System Log Insight content pack provides actionable data, for Windows OS operations managers, specifically for troubleshooting and pinpointing problems. The latest version of LogInsight product was announced during VMworld Connect on: Facebook. Feel free to network via Twitter vladan.

If not, the virtual machine is reset. This default value seconds can be changed using the advanced attribute das. Good stuff. You nailed it Didier….
