I have modified a F5 OID into the existing F5 verdor cert, the expressions are as screenshot attached here.
The OID 1.3.6.1.4.1.3375.2.1.14.3.1 has values from 0-4, only 4 means ACTIVE, all others values are considered as standby for me.
After that, the dashboards are showing the correct Active/Standby status although it only shows the past 300 seconds.
My question is: how can I set the threshold profile to generate alert whenever F5 status changes(from Active to Standby or Vice Versa)
I have set up a bunch CPU/Memory/Interface threshold profiles in the past. They raise events deciding by utilization of utilization percentages or number of packets etc...
But for this one, when I tried to create a threshold profile, it only gave me options such as "PCT of time in Active" or
"PCT of time in Standby", and decide by something such as "equal or more than" or "less than" a pct value. If I set as "equal or more than 100%" to raise an event, I have to set "less than 100%" as the required condition to clear the event. So, I guess I have to create another threshold profile for cases "equal or more than 0%" to raise and "more than 0%" to clear. (I already feel strange if I config this way)
So for most cases, F5 status switches happen all the time, normally we just ignore if they are working fine after status changes. But these threshold profile might still sending a lot alerts correct? Is there a decent way to send alert only when it changed the status?
Thanks!
