iRule for monitoring back-end server
Hello All,
Is there any iRule that can monitor the back-end server so if the back-end server is busy or dies, the pool member will be marked down?
So whenever back-end server is busy or dies, no more traffic will be sent to the pool member since it's marked down by the iRule.
So basically the two tasks of the iRule are monitoring the back-end servers and marking the pool member down.
Anybody has this similar experience or can anybody share how to create, a syntax probably?
Thanks.
- HamishCirrocumulusWell... Normally you'd use a monitor for this. But if you really really want an iRule to be intelligent enough (Or require the response time of a check NOW rather than the monitor timeout), you could craft the check yourself using a SIDEBAND connection.
