Check Logic Between Rule Groups

As you create custom monitors, compare and check evaluation logic to those used in Default roles. Make adjustments where needed.

The following infographic contrasts scan rules from a Default UPS with scan rules adapted for a Custom role.

 

Rule Meanings

Result Observed when Rule is True...

A Default UPS sub role scan-rule group that matches on any device detected with a populated SNMP v2 UPS module OR any device that satisfies the discovery criteria for the default functional category of "UPS."

The device will be identified as a UPS and have basic monitoring enabled. If the device is an APC brand, the APC-specific monitors (which happen to be part of the default role's monitoring list) will be applied.

A Default UPS sub role rule that checks for an enterprise MIB object with the value "318" (the vendor ID for APC).

The device will be identified as an APC brand UPS and have both basic and vendor specific monitoring applied.

Custom UPS sub role scan rules chained together by Boolean AND operators (match-all-rules). Checks first that SNMP MIB module for UPS exists on the device, then checks for the vendor ID that identifies the device as Liebert ("476").

The device will be identified as a Liebert brand UPS and have both basic and vendor-specific monitoring applied.
