need to determine if there is a "critical" flag in F5's MIB objects..??

Hi, I need to determine if there is a "critical" flag in F5's MIB objects...and how would I go about determining which object may carry "Critical" flag? I mean, there are myriad of objects, so how would someone rifle through them all and perhaps come up with the list of "critical" ones..??

Many thanks in advance for your help.
