LB::status behavior

Hi everyone,

 

In an irule, when a node is set to "forced offline", the LB::status return "DOWN".

 

There is a way to difference the status of a node between "forced offline" and "down" because de monitor fails?

 

Thanks

  • Hi Jose,

    Your behaviour is normal, you have to set your node to disable an not force offline if you want to diferency this 2 status.

    You can have 4 differents status:

    • up
    • down
    • session_enabled
    • session_disabled

    If your node is down or you force it to "forced offline" it will mark down too. If your node is disable it will mark "session_disabled". ...

    Check this article it will helpfull for you:

    Irule example with node disable...

    when HTTP_REQUEST {
    set maintenance_mode [LB::status node 192.168.250.1 session_disabled]
    if { ($maintenance_mode) } {
        HTTP::redirect "http://alternate.site.com/maintenance.html"
    } 
    }
    

    Let me now if it's clear for you.

    Regards
