I’ve changed the below, and I now get the following as the Nagios Status Information. /usr/local/nagios/libexec/check_apc_pdu.pl: line 24: use: command not found /usr/local/nagios/libexec/check_apc_pdu.pl: line 25: use: command not found /usr/local/nagios/libexec/check_apc_pdu.pl: line 26: use: command not found /usr/local/nagios/libexec/check_apc_pdu.pl: line 27: syntax error near unexpected token `(' /usr/local/nagios/libexec/check_apc_pdu.pl: line 27: `use utils qw($TIMEOUT %ERRORS &print_revision &support);' So I guess there’s a problem with the script after all. Strange, as it works when I run it from the command line as the nagios user. Back to the drawing board with that one I suppose! Thanks, Peter. </BLOCKQUOTE> <BLOCKQUOTE TYPE=CITE> Peter Roddan Senior Systems Analyst SBS Worldwide Ltd - Dartford DDI No: +44 (0)1322 424741 Email :<A HREF="mailto:Peter.Roddan@sbsworldwide.com">Peter.Roddan@sbsworldwide.com</A> Website :<A HREF="http://sbsworldwide.com">sbsworldwide.com</A> <IMG SRC="cid:image001.jpg@01CBF470.444E0770" WIDTH="334" HEIGHT="108" ALIGN="bottom" ALT="Description: http://www.sbsworldwide.com/_images/signatures/sig_logo.jpg" BORDER="0"> P Think before you print! </BLOCKQUOTE> <BLOCKQUOTE TYPE=CITE> </BLOCKQUOTE> <BLOCKQUOTE TYPE=CITE> From: Mike Lindsey [mailto:mike-nagios@5dninja.net] Sent: 05 April 2011 20:23 To: Nagios Users List Cc: Peter Roddan Subject: Re: [Nagios-users] Check_APC_PDU Command Definition </BLOCKQUOTE> <BLOCKQUOTE TYPE=CITE> Often, when you're getting an error and the only result you see is (null), what is happening is that your check script is printing to stderr. It might be that you have perl in your path, but the perl script's #! line doesn't declare the full path to perl, or there's an access error of some sort. But it's easy to figure out what's going on. Simply change your command_line to: command_line $USER1$/check_apc_pdu.pl -H $HOSTADDRESS$ -C public 2>&1 That will redirect standard error to standard out. Next time Nagios runs the script it will capture the full output of the script and you should see right in your Nagios ui, what the issue is.
