Why don't you just write your own alert script for Mon and
have Mon run it?
Thanks for your answer. I'd like it to be so easy but I'm afraid it
isn't. In my case I need to know the ip of the falling node and then
trigger a script that makes something with the rest of the nodes (I need
to modify the setup a mpi universe).
It seems to be possible to do this since the ip of the falling node is
received via mail.
Any ideas?
Should I need to use snmptrapd??
Thank you very much
Andrés.
I think you missed the point of the previous response. The mail you're
getting from Mon is being generated by an alert script. If you think there
is enough information in that mail to take an action on the failing node,
then there is enough information available to an alert script to just have
the script take the action.
Alert scripts in Mon are simply programs which take information in specific
ways from Mon and perform some form of action on that data. They can be
shell scripts, perl programs, C programs, etc. They can take whatever
action you deem reasonable. The command line arguments and environment
variables that are passed to alert scripts are documented in the Mon man
page.
