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. |
