Linux script monitor

I am trying to write a script (not a script guy) for Linux servers (not a Linux guy either) that will return the system uptime for a server.  I want to use 1.3.6.1.2.1.1.3.0 which is a timetick OID.  I found the following file in the C:\Program Files (x86)\SolarWinds\Orion\APM\SampleScriptMonitors\LinuxScripts directory but cannot get it to work.

When I run it I get this:

Output Result:

#!/usr/bin/perl

if (@ARGV[0] =~ /\bhelp\b/)

{

        print "ServerUptime.pl SNMPver community hostname\n";

        print "SNMPver - version of SNMP protocol\n";

        print "community - community name of SNMP protocol\n";

        print "hostname - Target host\n";

        exit 1;

}

# Get hostname and trim newline

$localhost = `hostname`;

$localhost =~ s/\s*$//g;

$hostname  = shift || $localhost;

$community = shift || "public";

$version = shift || "v1";

$results =  "";

$MIB= "1.3.6.1.2.1.1.3.0";

$outres = "snmpget -$version -c $community $hostname $MIB |";

open(OUTSTD,$outres) || die "Unable read pipe\n";

while ($line = <OUTSTD>) {

             $indval = index($line,"=");

             $indval = index($line,":",$indval);

             $val = substr($line,$indval+1,length($line) - $indval);

             $val =~ s/[\/\n]//g;

             print "Message: Server Uptime at host \"$hostname\": $val\n";

             print "Statistic: $val\n";

         exit 0;

}

print "Statistic: 0\n";

exit 1;
