Hi, this is an interesting question...what do you mean with 'monitoring' ? you want to collect metrics, alerts based on thresolds, event collections? You want agent based monitoring or agentless? I've used in many years: - OEM - Cacti - Nagios - Adventnet products - HP Openview/Tivoli Monitoring your systems may not be a plus and may not be downsized to few metrics....
