VMware ESXi
Introduction
The VMware esx-probe uses the VMware API to monitor VMware ESXi hosts.
Features
THe ESXi probe can be used to monitor standalone VMware ESXi hosts as hosts part of a VMware V-center deployment.
We have a default label that contains specific conditions for monitoring stand alone ESXi hosts.
See our overall VMwware documentation for additional information.
- Configuration issues
- Hypervisor status
- Datastores
- Virtual datastore provisioning
- Actual capacity on the datastore
- Virtual capacity space actual virtually provisioned when using thin provisioning.

VMware guest monitoring
We offer a specific probe for VMware guest monitoring to retrieve even more in-depth metrics per virtual machine. See our VMware guest documentation for more information.
Configuration
Credentials
The VMware API requires a user account which is assigned the Read-only rol on each monitored ESXi host.
See the VMware documentation on how to setup a local account and assign this accountto the Read-only role.
Don't use root
We strongly advise setting up a separate user for monitoring to have a clear separation of responsibilities but also to avoid lock-out issues.
Operational
Known issues
Cached API response
Sometimes InfraSonar reports different values than VMware consoles.
The cause for this is that the VMware API sends cached data as a response to queries.
The solution to mitigate this situation is to clean the VMware cache using the following commands on the affected ESXi host:
localcli hardware ipmi sel clear
etc/init.d/sfcbd-watchdog restart
etc/init.d/hostd restart
etc/init.d/vpxa restart
