iCall, SSH and run a command.

i have two pool members. 10.50.169.14(active) and 10.50.169.16(passive). I have a health monitor of port 7222 on active member. what i want through iCall is that when this pool member gets down F5 SSH into pool member 10.50.169.16 and run a command to run the application. I know the command but i do not know anything else how to do it. Please help

 

Thanks

    If you have a script on the F5 which can remote ssh non-interactively on to your server and execute whatever you need executed there, then 1 way to do this is via custom alert under /config/user_alert.conf.

     

    You can setup an "exec" script which runs if a log message matches a defined string pattern. You will have to set this string pattern for the exact pool name and member values for which you want to execute the script for.

     

    I would not recommend this approach if you find a better way. Log strings do change from version to version and also this creates a new process on your LTM if the log message matches the string pattern, which could be a potential hazard if the server flaps around.
