SNMP trap/probe – with or without the dot in the OID?


I was setting up some UPS monitoring at a costumer, and i got into a “discusison” with a collegaue about the first dot in a OID. We were discussing whether or not you need the dot before the first number when creating monitors/rules in SCOM 2012.

We went ahead and created two simple monitors – one with the dot and one without:

UPS Battery Temperature:



UPS Battery Temperature – WITHOUT DOT:


I faked a temperature alert and i got:



I got two alerts! So actually, apparently it doesn’t make a living difference if you use the dot or not. However, I do recommend using the dot, as the dot is always listed in the MIB.

Happy monitoring your network equipment with or without dotting!

    Hi Michael,

    How do you add those UID’s?
    Is it a SNMP monitor or rule? Trab or Probe?

    I have a NAS and have only ICMP data and would like to add CPU and memory (I have OID’s list) but so far nothing from NAS
