I hope this post finds you well. We recently purchased the F5 and found that being on 10.4.2 code is the trick for getting a huge improvement in status retrieval. We were operating on 10.3.1 code when installation occurred and I found that nothing of significance existed. Solarwinds made huge improvements to the MIB polling and GUI in this version of code. Don't mess with custom pollers, etc. Go to that code first and work from there.
