SNMP Extended

SNMP Extended monitor checks one or more OIDs, each against its own threshold, using an XML file you import into the monitor. The XML file contains a list of SNMP parameters (OIDs) to monitor. Threshold operators (greater than, less than, equals, contains, etc.) within the monitor dialog enable you to precisely enforce up or down status against expected values you provide with respect to your device and network environment needs and service level policies.

Tip: You can create your own XML lists of SNMP OIDs and add them to <install-directory>\Data\SNMPExtended\ on the file system where you installed WhatsUp Gold.

The following figure shows SNMP Extended configuration from Monitors Library.

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 management objects from the imported XML.
• Configure. Click to build an expression. This expression will be applied to the parameter value (MIB) observed at the device:
  • 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.

Add custom SNMP parameters (custom SNMP monitors defined by XML files)

When you add SNMP parameters to an XML file, WhatsUp Gold expects the following format:

Syntax

<SNMPParameter Name="MibObjectName">
<ShortDescription>ObjectValueDescription</ShortDescription>
<LongDescription>DetailedObjectValueDescription</LongDescription>
<Type>MibObjectValueType</Type>
<IndexOID>IntegerInstanceValue</IndexOID>
<OID>RequiredObjectId</OID>
<DisplayOID>OptionalDisplayTheOID</DisplayOID>
<Units>OptionalUnitsAssociatedWithOIDValue</Units>
</SNMPParameter>

Example

<SNMPParameter Name="IcUpsAlarmUpsOff">
<ShortDescription>Onboard alarm state</ShortDescription>
<LongDescription>Indicates the inverter (battery power) and bypass to wall power are both off</LongDescription>
<Type>Value</Type>
<IndexOID />
<OID>1.3.6.1.4.1.476.1.1.1.1.6.3.12</OID>
<DisplayOID />
<Units />
</SNMPParameter>
