[lvs-users] LVS Process Monitor

[Jason Ledford]

I am currently trying to setup a 1 nic lvs-nat.  My test environment has 2 real smtp servers and 2 directors and all have ip's on the same subnet.  I am using heartbeat for failover to the other director.   Not all failures are going to be machine failures, so if by some chance my primary director drops the ldirectord process but the machine doesn't shutdown, failover doesn't happen.  So I need a way (or script) to monitor if ldirectord is up and if not initiate failover.

I would use a script to monitor smtp but when I am on the director I can't connect to the service offered on the VIP (if this is not normal let me know) .  Does anyone have any other automated way to detect software failure and initiate failover?

TIA for any help.
