Reporting of hitting Connection Limits
We're using pool-member connection limits to prevent servers being overloaded. We can see from the statistics that these limits are being hit. The same statistics suggest that we're hitting the sum of all of the member limits, which would imply that we're turning some connections away.
I used these limits in a previous job running on LTM 9.x, and I remember getting log messages when the overall limit had been hit and turnaways have occurred. However, we're not seeing any such messages on 11.2. We currently have the "Layer 4" category as Informational.
I thought there was an SNMP trap in this case, as well. However, I don't see any relevant entries in /etc/alertd/alert.conf, nor do I see any MIB entries that seem relevant.
Is there any built-in way of getting an alert when we reject a user? Is it necessary to use an iRule to get this information?
