vSphere HA – VM Monitoring

VM Monitoring comes with three different options. By default it is set to Disabled but you can vm monitoringenable either VM Monitoring Only or VM and Application Monitoring.

In either case, the VM uses VMware Tools to identify the state of the VM and its application and then reboot the VM if necessary.

What is the difference between VM Monitoring Only and VM and Application Monitoring?

VM Monitoring Only utilizes VMware Tools to check regularly for heartbeats and I/O activity from the VMware Tools process. Depending on the Monitoring Sensitivity setting, vSphere HA will  know how often to look for heartbeats and how often the VM should reboot.

VM and Application Monitoring also utilizes VMware Tools and can monitor the VM just like the VM Monitoring Only setting but it can also monitor the application, running on the VM. In order to enable Application Monitoring the application has to support VMware Application Monitoring or use the appropriate SDK.

At a minimum it is best practice to enable VM Monitoring Only to ensure maximum availability for your most important VMs. Note, this setting can be adjusted per VM via VM Overrides in the Cluster Settings

Today Eric Siebert from vSphere-land announced the final results of the Top vBlog 2016 competition.

For the readers who aren’t familiar with the Top vBlog competition, it is all about best content and frequency of content. Last year I wasn’t even on the list to be voted for. However, this year I made it on the list and I’m ranked 72 out of 321 blogs.

Not bad at all. I’m super excited and thankful for everyone who took the time to vote for me and my blog. You are the reason I’m sharing my stories and my knowledge.
