Need a Indexer

Hello guys,

What I am looking for is a alerting system that can monitor a vcenter or multiple vcenters and push back alerts when anything changes.

For example - If I want to know when my customer logged into the vcenter and when he powers on a vm or when he creates a new vm - the system should immediately or in about 5 minutes identify this and alert me or do some action.

Any software out there that does this.

Please advice.

Thanks

RJ
