Node settings->Monitoring->Network Services
NetCrunch allows you to select the monitoring type for selected nodes.
For each monitoring type, the leading service and checking time can be defined.
Simplified Monitoring
Apart from any network services discovered on the node, various performance counters can be tracked on a node if it has full monitoring enabled.
Monitored counters will depend on which operating system the node is running and if it is SNMP-manageable.
To permit NetCrunch to monitor a larger number of nodes and reduce resource usage, you may enable simplified monitoring for any node. Selecting this option for a node tells the program not to collect any performance data (related to Windows, Linux, BSD, Mac OS X, Solaris, ESX or SNMP). Only network services that were previously discovered on the node will be monitored (e.g. PING or HTTP).
Standard Monitoring
Apart from any network services discovered on the node, various performance counters can be tracked on a node if it has standard monitoring type enabled. Monitored counters will depend on which operating system the node is running and if it is SNMP-manageable. Such counters are displayed in the main status window.
Extended Monitoring
The extended monitoring type (similarly to standard monitoring type) allows monitoring performance counters on the monitored nodes. Therefore, the performance data are collected by NetCrunch. The only difference is that extended monitoring allows setting less than 1 minute checking time for the selected leading service.
The extended monitoring type can be selected for nodes without dependency rule. If monitoring of the selected node depends on a node another than NetCrunch node (node with installed NetCrunch Server), the appropriate information is displayed.
If the TCP based network service is chosen, the leading service the checking time can't be less than 15 seconds.
