Hi Daniel,

 

If you have equal connections going to all four pool members then you could simply track the total connections on the virtual and block from there rather then disable a pool member.

 

 

The irule I had in mind is the following

or

For alerts you can go to the following

 

 

 

SOL3667: Configuring SNMP trap alerts to send email notifications

SOL3664: Configuring BIG-IP to deliver locally-generated email messages

 

https://support.f5.com/kb/en-us/solutions/public/3000/600/sol3664.html

 

 

And if you want to generate a message based on a custom log event, refer to SOL3727:

 

 

SOL3727: Configuring custom SNMP traps

I hope this helps
