Hello,
We've just segmented our servers behind an internal firewall link and have noticed some strange issues with APM and the Fortigate. After installing the link, there is a noticeable linear climb in session count on the Fortigate up until about 35k. At that point, the APM monitors start to flap between Up/Unknown (when I know for a fact one of those services is hard disabled) and down repeatedly every 10 or so minutes. The issue only stops when I restart the Solarwinds server to reset the climb. The strange thing is the server doesn't show in the 'top destinations' or 'top sources' in the FortiAnalyzer. At ~20k sessions, it should be at the top of the list.
Anyone have any ideas or where I could check?
Thanks!
