From the HyperFlow SK:
When an elephant connection triggers HyperFlow, the output of the "top
" and "ps
" commands can show that HyperFlow user space processes consume the CPU at 100%.
This occurs because HyperFlow constantly polls its queues to handle incoming jobs. After the elephant connection closes, the output of these commands shows that the user space "us
" consumption returns to usual levels because Hyperflow goes down and stops processing jobs.
To see the actual load on the CPU, use one of these:
- CPView (CPU > Overview > Host)
- SNMP (the OID tree 1.3.6.1.4.1.2620.1.6.7.5)
- SmartConsole (right-click the Security Gateway object > click Monitor > from the left, open System Counters and click System).
This does not trigger inspection bypass because of a high CPU load.
