Performance metrics of an agentless server monitor
Site24x7's agentless server monitoring monitors all your servers using SNMP and WMI credentials for important metrics like response time, packet loss, services, processes, and disk-related metrics using performance counters and tabular performance counters. You can also configure to receive instant downtime alerts by configuring threshold profiles.
Navigate to the server tab and click on a agentless server monitor to view different tabs like:
