Monitor receive disable and persistence

The customer wants to control disabling of specific nodes. We have therefore implemented a "receive disable string" in the monitoring definition, enabling him to put "offline" into a static monitoring...

Hi Michael,

 

 

thanks for your reply and sorry for my late feedback!

 

I'm aware of how monitoring works, but the customer is a bit difficult and insists on not changing the monitoring as it is today, thus we need to solve this using an irule.

 

As I already suspected, the LB::reselect command does indeed run into the same issue, meaning it will look for a persistence entry and then make the load balancing decision based on that (which is exactly what we do not want).

 

 

 

I will give this one a try:

 

 

 

when LB_SELECTED {

 

if { [LB::status pool poolname member [LB::server addr] port [LB::server port]] eq "session_disabled" } {

 

persist none

 

LB::reselect

 

}

 

}

 

 

 

Greetings

 

Martin
