ACE 4710: take an action when a rserver goes down

[billmatthews]

If we use an ACE4710 to load balance two real servers, obviously it will use health checks to determine if a server is down.

When it detects a server is down, it will not send it any more traffic.

But can we also have it take any other action?  For example maybe email an admin, or send an SNMP trap?  Or better yet, can we use a custom TCL script to do other things, like launch some custom activities?

Thanks for all the help!

Hi Bill,

I think you can refer to  "cesRealServerStateChange"

(http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=cesRealServerStateChange&translate=Translate&submitValue=SUBMIT)

as SNMP trap that is sent when a rserver goes down.

Then once your poller has received that you can defined the activities that will take place upon the reception of the trap.

Which other custom activies would you like to perform?

Thanks Alessandro, an SNMP trap for cesRealServerStateChange will probably work perfectly.  I'll just need to setup a trap colllection workstation and have it take actions when the trap is received.
