We added some F5 viprion 2400 devices into OPM in order to monitor CPU、Mem and Activeconnections. 

    However, the CPU of F5 always stuck at 97% and I check the CPU OID matches the MIBs of F5 as given link, but I check the F5 CPU dashboard always display about 25%.

    In addition, the activeconnection value display a few hundred connections, even 0 from OPM snapshot. However, I use the same OID to get the value about 60K in OPM MIBbrowser, that's so weird. Please give your advice, thx in advance!
