Hobbit 4.2.0 on RHEL4, BB client 1.08d on Windows XP cici.

hobbit-alerts.cfg:
 HOST=cici       SERVICE=procs,svcs
          SCRIPT /home/hobbit/server/etc/alert-svcs.sh  cici

Some environment variables,e.g,BBSVCNAME,BBHOSTSVC are used in alert script,
but they actually weren't shown as specific service or process that triggered the alert while the service or process reached down, just generic string procs.

alert-svcs.sh 
#!/bin/sh
echo "$BBHOSTSVC   reached error  state" |write hobbit
echo "$BBSVCNAME   reached error  state" |write hobbit
  

The result displayed as below:

Message from hobbit at my_linux on <no tty> at 22:21 ...
cici.procs   reached error  state
EOF

Message from hobbit at my_linux on <no tty> at 22:21 ...
procs   reached error  state
EOF


Thanks a lot.

Regards,
Case

Actually, that's exactly as it should be. BBHOSTSVC contains the
hostname "cici" AND the servicename "procs", joined together with a 
dot. So an alert from hosts cici for the procs column has
BBHOSTSVC=cici.procs

BBSVCNAME is the service name, "procs" in this case:

which is what you also get.

If you want just the hostname, use BBHOSTNAME. See the hobbit-alerts.cfg
man page for a listing of what the various variables contain.

In your script, do a "set > /tmp/foo" . When hobbit runs the script,
look at /tmp/foo you'll see all the environment variables used by
hobbit. lots of stuff, you'll see the ones you're looking for.

Hi Henrik and Daniel,

Thanks for support.

Mail message would include specific information about related process or
service' name  if we use MAIL in hobbit-alerts.cfg, e.g. "&red Cisco
Systems, Inc. VPN Service - Stopped".

How can we display similar messages in alert script while a process or
service triggers the alert?

Thanks a lot.

Regards,
Case

The full status message text is passed in the BBALPHAMSG env. variable.
Process that to pick out lines with "&red", "&yellow" and so on. E.g.

   echo "$BBALPHAMSG" | egrep "^&red|&yellow"

Note that lots of network check ( the ones defined in bb-services ) will not report statuses on a line starting with &color, they start with "Service..." . The following perl snippet is what I use to pick out statuses in my custom notification script.


        $subject="$ENV{BBHOSTSVC}: $ENV{BBCOLORLEVEL} ";

        foreach( split('\n',$ENV{BBALPHAMSG}) ) {
                if ( /^\&(yellow|red|purple)/ ){
                        $message .= $_;
                }
                if ( /^Service.* not OK/ ){
                        $message = $_;
                }
        }


Then use smtp mail to send out an email, you can concatenate $subject and $message togheter to if you whish to send out a message with no subject, nice for phones and pagers.

Enjoy
