SNMP Extended

The SNMP Extended monitor utilizes SNMP to gather specific information about the functions of multiple OIDs by querying the group to verify they return a expected value and allows you to monitor all devices using SNMP. While the standard SNMP monitor checks a single OID against a single threshold, the SNMP Extended monitor checks multiple OIDs against multiple thresholds using an .xml file and predefined values for each supported device type to determine if the monitor is considered either up or down according to the returned value.

Provide a unique name and description for the monitor, then configure the following:

Import. Click to select the desired .xml file from the list containing applicable OIDs to monitor, then click OK to return to the monitor configuration dialog. The Thresholds to monitor section of the dialog displays the OIDs from the imported .xml file as parameters.
Configure. Click to specify the request type for the selected parameter.
- value is. When monitoring for a specific value, determine when the monitor should the report the device as Down by specifying if the response is greater than, less than, equal to, or contains the entered numeric or string value.
- value is outside the range of. When monitoring a range, enter the minimum and maximum values the response must fall within for the monitor to report the device as Down.
- rate of change between two polls is. When monitoring for a range of change, determine when the monitor should the report the device as Down by specifying if the response is greater than, less than, or equal to the entered value in seconds.

Enable monitoring for specific parameters by selecting the respective checkboxes. Click Advanced to set the SNMP timeout and number of retries as well as enable Use in Rescan if desired.
