Hello, Using NRPE 2.12 and have an issue with a variable from a perl script not being printed. The script works fine when executed manually using the 'nagios' user which NRPE is running as: sh-2.05a$ /usr/local/nagios/libexec/check_apache OK - 68 requests being processed. However, via NRPE: /usr/local/nagios/libexec/check_nrpe -H localhost -c check_apache OK - requests being processed. Below is the script. I've tried many different code variations, but end result is the same. I appreciate any insight as to what the issue could be. Thanks! ------ #!/usr/bin/perl $OK = 0; $WARNING = 1; $CRITICAL = 2; $status = $OK; $returnstring = ""; ($apache_tool, @lines, $tot_req); $apache_tool = "/usr/local/apache/sbin/apachectl status"; @lines = `$apache_tool`; foreach (@lines) { if ($_ =~ /requests currently being processed/) { $tot_req = (split(" ", $_))[0]; last; } } if ($tot_req < 350) { $status = $OK; } elsif ($tot_req >= 350 && $tot_req < 450) { $status = $WARNING; } elsif ($tot_req > 450) { $status = $CRITICAL; } if ($status == $OK) { $returnstring = "$tot_req requests being processed.\n"; print "OK - $returnstring\n"; } elsif ($status == $WARNING) { $returnstring = "$tot_req requests being processed.\n"; print "WARNING - $returnstring\n"; } elsif ($status == $CRITICAL) { $returnstring = "$tot_req request being processed.\n"; print "CRITICAL - $returnstring\n"; } exit $status;
