Reacting when stats cross specific threshold

The only way I found to monitor active sessions is to create a complete iRule monitoring: https://devcentral.f5.com/s/feed/0D51T00006i7MGlSAM

 

However, It's seems a very aggresive method (too much variables and processing), we would like to have less impact in our production enviroment.

 

I wonder if it's possible to get the current active connection statistic using something like this: https://clouddocs.f5.com/api/irules/STATS__get.html

 

Anyone knows how to do it?

 

An example of using will be also useful (with a default statistic, not custom)...

Hello,

Maybe an easy way it is configuring connection limit or connection rate limit and configure snmp alert when the limit is reached looking for the log entry similar to:

Warning, connections equals limit 192.168.42.95:55587 -> 20.48.40.20:3306, proto TCP, VS /test/VS_GALERA_3306: Connection limit reached.. 

Be careful, because once the limit is reached new connections are rejected so my propose is configure connection limit in the pool member.
