iRule actions depending on available resources
If I may add.
for what [cpu usage Xsec] value I should set the threshold to skip the resource consuming iRule? (which values indicates a high CPU usage and what does the value it self indicate?).
It really depends on a lot of variables, but a noticeably high CPU threshold (something you'd want to do something about) might be between 80 and 90%. The number should be an average of all TMMs and should also be visible via command line:
tmsh show sys performance
I would caveat that arbitrary CPU limit with the notion that the [cpu usage ] command itself will induce some CPU overhead.
Can the memory consumption of the tmm instance be measured within the iRule? So fare I see no other solution than parsing a file from the filesystem which I regularly update...
