Memory monitoring in What's Up Gold

The memory monitoring of LTM in What's Up Gold indicates that the physical memory usage is always 99%. I checked in the performance tab on LTM and it indicates that OS Used Memory is really 99%, but the TMM memory usage is under 10%. And I think this TMM memory usage should be what we want to see.

How can I make WUG to correctly monitor the memory usage? Which memory usage I should monitor on LTM?

 

Thanks a lot.

  • Hi,

     

     

    Which LTM version are you running? Are you polling using snmp?

  • Hello, We are also experiencing this issue, although we're using a different monitoring product. We use CA Spectrum to poll SNMP on our LTM version 10.2.2, build 930.0. Any suggestions?
