<html> <head> <style></style> </head> <body class='hmmessage'><div dir='ltr'> I recently ran into a similar testing Nagios/NagVis/PnP4Nagios. To throw it out there... you are using an older version of PNP as they're beyond 0.6 now. I was trying to add a new service and testing. I had been tweaking the check's command line options to find the write output I wanted. Once the check worked how I wanted, I noticed I was getting an error on the graph. Since this was a new check, I deleted the existing RRD files that had been created and let new ones get created. That corrected the issue. I assume the RRD file was initially created with incorrect parameters as I was changing the check during my initial testing. -- Mat W. <div><hr id="stopSpelling">Date: Thu, 28 Jul 2011 17:18:58 +0530 From: Navdeep.Sidhu@tatatel.co.in To: nagios-users@lists.sourceforge.net Subject: [Nagios-users] RRDTool exits with errors -> ERROR: can't make a graph without contents <meta http-equiv="Content-Type" content="text/html; charset=unicode"> <meta name="Generator" content="Microsoft SafeHTML"><style> .ExternalClass p.ecxMsoNormal, .ExternalClass li.ecxMsoNormal, .ExternalClass div.ecxMsoNormal {margin-bottom:.0001pt;font-size:11.0pt;font-family:'Calibri','sans-serif';} .ExternalClass a:link, .ExternalClass span.ecxMsoHyperlink {color:blue;text-decoration:underline;} .ExternalClass a:visited, .ExternalClass span.ecxMsoHyperlinkFollowed {color:purple;text-decoration:underline;} .ExternalClass p.ecxMsoPlainText, .ExternalClass li.ecxMsoPlainText, .ExternalClass div.ecxMsoPlainText {margin-bottom:.0001pt;font-size:12.0pt;font-family:'Calibri','sans-serif';color:black;} .ExternalClass span.ecxEmailStyle17 {font-family:'Segoe UI','sans-serif';color:black;font-weight:normal;font-style:normal;} .ExternalClass span.ecxPlainTextChar {font-family:'Calibri','sans-serif';color:black;} .ExternalClass .ecxMsoChpDefault {;} @page WordSection1 {size:8.5in 11.0in;} .ExternalClass div.ecxWordSection1 {page:WordSection1;} </style><div class="ecxWordSection1">Hi I'm using Nagios 2.8 with RRD tool version 1.0.50 & PNP version 0.3installed. Nagios is running on RHEL-4. I'm facing an issue in RRD Tool. Recently I have configured this toolfor Cisco devices (under serviceextinfo.cfg file) so that memory & CPUutilization should be available in graphs however I'm getting followingerror when trying to view the graphs. RRDTool exits with errors -> ERROR: can't make a graph without contents. This tool is working fine with Intel platform servers & displaying thegraphs however not working in Cisco devices. I’m pasting excerpt of my host configuration & serviceextinfo file to provide clear picture. In fact, in Nagios web console, I’m able to see Memory & CPU utilization of Cisco devices however unable to view the graphs. I’m using check_snmp_mem.pl plugin to capture Memory utilization of Cisco devices. Let me know if any other info required from me. Excerpts of host Configuration File define command{ command_name process-service-perfdata command_line /usr/bin/perl /usr/local/nagios/libexec/process_perfdata.pl } Excerpts of Serviceextinfo File define serviceextinfo{ host_name L3-Switch service_description MEM action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$ } I would really appreciate your help in this regard.
