The Simple Network Management Protocol (SNMP) monitor allows you to access SNMP supported devices and plot the performance output on a graph.

The SNMP performance monitor requires one or more of the following credentials:

  • SNMPv1
  • SNMPv2
  • SNMPv3

Configure the SNMP performance monitor using the following boxes:

  • Name. Enter a unique name for the performance monitor. This name displays in the Monitor Library.
  • Description. (Optional) Enter a short description for the performance monitor. This description displays next to the performance monitor in the Monitor Library.
  • Performance Counter and Instance. Enter the OID and instance in the respective fields or click browse (...) to access the MIB Browser. The MIB Browser dialog appears.
  • Enter the name or IP address of the computer you are trying to connect to in the Select counters from computer box. You can click browse (...) to select a device from a list.
  • Select the SNMP Credential used to connect to the device. You can also click browse (...) to access the Credentials Library to create a new credential.
  • Timeout and Number of Retries. (Optional) Adjust the time and retries count for the computer you want to use to connect to the device.
  • Click OK. The SNMP MIB Browser appears.
  • MIB. Use the navigation tree in the left panel to select the specific MIB you want to monitor. You can view more information about the property/value at the bottom of the dialog.
  • Property. In the right panel, select the specific property for the MIB you want to monitor.
  • Click OK to add the OID to the Performance counter and Instances boxes of the Add SNMP Performance Monitor dialog.
  • Plot raw values. Select this check box to monitor the current polled value instead of tracking the rate of change over time.
Note: Enable Plot raw values when you want to graph the current value of the SNMP object, as one of would a gauge such as a vehicle's speedometer or temperature sensor, for example. Disable this option when graphing objects that measure a rate of change over time such as an odometer or the number of times an engine's RPM exceeded a certain threshold.
