About memory threshold setting

Michaelyang

Hello,

Is there a way to have F5 set a threshold for memory and then display it on /var/log/ltm when the set threshold is exceeded?
What about an alert every minute after it is exceeded?

Any help is appreciated.

you could create an iCall script with a periodic handler that can assess the current memory state, and given your specified threshold, log or alert on that information. Here is a list of iCall articles you can reference to see if you'd like to tackle that effort. Another alternative would be to use SNMP from a centralized management station and alert locally there, but I'm assuming your environment there.

Also F5 eviction policies can help to start dropping packets at a particular CPU level for the device or an F5 Virtual Server:
