Monitor status of a Linux service (Tenable LCE)

smdcia

Been messing with this all day and probably going about it the wrong way. In a nutshell, I'm trying to monitor a process (lced) for up/down status. The code below will tell you (from the command line) if the "lced" process is running or not. I've been trying to get the application monitor to work with this code. Any ideas? 

#!/usr/bin/perl
#use strict

my $service = ("lced");
my $host = `/bin/hostname`;
chomp $host;

#print "$host\n";
#print "$service\n";

my $status =`/bin/ps cax | /bin/grep $service`;
#print "$status\n";

if (!$status) {
print "$service stopped\n";
}

Below is an example to assist you based on what you posted.  It looks at the end of the process list line for the matching argument (service name) and then posts the result to the Statistic field (zero being success in this case) The example looks for the snmpd service.  Please note this is not a tested or fully functional script (other than quickly on my personal server) and designed to assist you with your particular script.

$result = sprintf("/bin/ps cax | /bin/grep -w \'.*%s$\'", $service);

system($result);

printf "Statistic.proc: %d\n", $?;
