Here is a good Meet the Features – Orion NPM 10.1 – Virtual Infrastructure Monitoringto read on the new features in 10.1 around this.
We can poll either through vCenter or each ESX host individually. If you go through vCenter we pull the cluster and data center information as seen in the above post I referenced. All of the values and stats we pull can be alerted off of in the advanced alerts manager. You can also configure VMWare to send Syslog for things like vMotion and alert off of those as well.
Let me know what other questions you have.
Can someone provide the necessary steps involved with successfully discovering and adding a vCenter to Orion NPM v10.1.1?
thanks in advance,
