Unlike device, interface, or service alerts, the trigger conditions for OIDs (object identifiers) appear after you’ve added a new monitor setting. That means the variable is built from the name you give the monitor setting.
The first word in the monitor setting name is always entirely lowercase. Any subsequent words are capitalized on the first letter.
Monitor setting name: Environmental probe
If the monitor setting name includes a special character (e.g., hyphen, bracket), these characters are excluded from the variable name.
Monitor setting name: Last self test result (UPS)
