Alert For Memory Usage Threshold

Hi All,

If i understand correct, i can create a custom SNMP trap that is triggered whenever memory usage is high, add the following trap definition to the /config/user_alert.conf file:

alert MEMORY_HIGH_STATUS " Aggressive mode (.*)" {

snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.500" }

Reference Link : https://support.f5.com/csp/article/K3727

But this again does not serve my purpose where i should be alerted when let's say tmm memory utilization crosses 50 % or may be even before.

How do i achieve this ? Any recommendations ?
