ASM bypass_upon_load variable
Hi all,
when you enable the bypass_upon_load variable , web application traffic bypasses the BIG-IP ASM system when there are insufficient resources for BIG-IP ASM service.
I would like to know what is the threshold that triggers the process (high threshold) and if ASM returns to service automatically when resources are available again (low threshold).
Thank you
By default, the bypass kicks in if the system idle is under 10% (i.e., is 90% used); this can be altered by changing the "bypass_under_high_cpu" system variable from 10 to some other value.
/usr/share/ts/bin/add_del_internal update bypass_under_high_cpu <value>
Sample log when the event has started:
"High CPU Utilization: event code I617 Bypassing ASM"
There is no log indicating the event has ceased, you'll just stop seeing additional logs.
