Unix script monitor

shanepj

I am running a very basic script to check the status of the BMC patrol agent on our unix servers.  I am having consistenct issues.  I am running a script that telnets to port 3181.  If it returns "Who are you?" the agent is up and running.  Using the following script works for most of the servers.  The others I can ssh to the server from the APM server.  I can login with the credentials I have set up.  And I can then run the same command and get the proper return response.  Any thought or ideas to help me get this consistently working would be appreciated.  Also I am not much of a perl scripter so if there is a better way to do this feel free to let me know.

#!/usr/bin/perl

$patrol = `telnet localhost 3181 | grep Who | grep -v grep`;

if ( $patrol ne "" ) {
        print $patrol;
        print "Statistic: 0\n";
        exit 0;
}

print "Statistic: 1\n";
exit 1;

After a little tweaking I have finally got the script to work for 99% of our servers.  I now get on a few servers a pretty consistent error of "Checking of directory existence failed"  Any thoughts?  Again if I ssh to the server and login with the crendentials and run the command it all works just fine.  I am just having trouble getting APM to work.

#!/usr/bin/perl

$patrol = `telnet localhost 3181`;

unless ( $patrol =~ m/Who/ ) {
        print $patrol;
        print "Statistic: 1\n";
        exit 1;
}

print "Statistic: 0\n";
exit 0;
