File Monitor

Hello all;

 

I need a monitor maybe you know.But i don't remember the how. I have a vıp nad a pool that has got 2 nodes. I create a custom monitor on the nodes.Nodes are Windows Server. My monitor check a txt file on each servers.That txt file in the for example "\server1\d\f5mon\f5mon.txt" . So The txt file include "0 or 1 ". When i get 1 my custom mon is up.When a server admin change the txt file to 0 (zero), my F5 monitor down and F5 does not push the traffic.

 

So What is the monitor parameters? Do you have any ideas? Thank you for any help.

 

Regards. Ferhatde

    1) The txt file must actually be hosted in web-server directory, and not just 'located somewhere in the server', I mention that because you used 

    \
    instead of 
    /
    when mentioning your txt file location. Even when using Windows Server, the HTTP paths (directories) at the client-facing front-end are distinguished by 
    /

    2) First check if the txt file opens directly in HTTP response body at 
    http://web-server-ip/server1/d/f5mon/f5mon.txt
    . If yes, something like this may work: 
    ltm monitor http mon_http_custom {
    defaults-from http
    destination *:*
    interval 5
    ip-dscp 0
    recv 1
    recv-disable 0
    send "GET /server1/d/f5mon/f5mon.txt HTTP/1.1\r\n"
    time-until-up 0
    timeout 16
}

    Regards,
