What tool do you use to monitor your servers?
What are the "best" monitoring solutions for mixed infrastructures ?
i have been looking at the options and Nagios really look like to be the most complete software.
Is there any other solutions i should be testing before purchasing ?
We have about 25 servers (most on Vmware, some physical) on 2 different sites and looking for real time SMS alert and detailed reports.
Another plus would be a software that can also do network traffic monitoring.
