Pool or Node Monitoring and redirection

Hi,

 

 

I have F5 ASM and need somehow to monitor pool or node and if status of one or another is "down" then redirect traffic to other pool and make http:redirect.

 

I didnt find anything in forum search...

 

 

 

Itried to do something like this:

 

 

 

when HTTP_REQUEST {

 

if { [active_members My_pool1] < 1 } {

 

pool My_pool2

 

HTTPS::redirect "https://abc.com/one"

 

 

 

But this is not working... :/ I asked F5 support do I need LTM license in order to use this commands (active_members, LB:seerver, etc) but they could not tell me that..

 

 

 

Can someone suggest what can be done in order to monitor pool/node and then take action based on monitor result ?

 

 

 

thank you in advance

 

 

 

 

 

Vytautas.

    Hi Vytautas,

    Give this a shot:

    when LB_FAILED {
        HTTP::redirect "https://abc.com/one"
    }

    You probably don't want to select a pool then send a redirect to client. I would do one or the other. I can't say for sure that this will work on an ASM standalone, but I'd lean towards yes. Give it a shot.
