Syslog notification in case of pool priority group change

Hi,

I am wondering if there is any way to receive a syslog / email / snmp notification in case of pool priority change.

For example, i have a pool with 5 members in it. 3 of them with priority of 100 and the other two has priority of 50.

I dont care if 1 member fails , but i want to know in case the first 3 members fails and the traffic switched to the other priority group.

Is there any way to configure it?

    Guy-M,

    Unfortunately there isn't a specific log for priority group activation. I've created an iRule below that you can work with to create a log entry in /var/log/ltm, assuming you have remote syslog configured it will ship out to your remote location. You can update it to include more members if need be.

    when LB_SELECTED {
	log local0. "staus [LB::status pool /dev-test/https_pool member 10.2.0.33 80] "
	if { [LB::status pool /<partition>/<pool> member <pool_member_IP> <pool_member_port>] eq "down" and [LB::status pool /<partition>/<pool> member <pool_member_IP> <pool_member_port>] eq "down" } {
	log local0. " Priority group 2 down for <pool> with partitions!"
	}
}
• Please replace <partition>,<pool_member_IP>, <pool> and <pool_member_port>, remove the angle brackets. Example: Common, 10.10.10.1, 80.
