Howdy, I'm running Nagios Version 3.2.0 and I've got a very odd issue with Nagios PNP with stats collection. We run about 30 instances of Clammy on the server being checked. I have a script which basically collects data about each instance of Clammy from a PS command, parses the data and outputs to Nagios. I pass specific dataset values via a pipe | to Perfdata and everything works great...as long as I don't try to get data on more than 2 instances of Clammy. For example, here's the value of Performance Data when checking only 2 Clammys: Clam_num=1;Scan_%=68.5;Scan_num=1943;Cache_%=31.5;Cache_num=895;Scan_per_sec=9.5; Clam_num=2;Scan_%=66.7;Scan_num=2552;Cache_%=33.3;Cache_num=1273;Scan_per_sec=12.8; That works great, and PNP graphs the values just fine. However, if I make the check for 3 Clammys, I get the following output: Clam_num=1;Scan_%=68.5;Scan_num=1943;Cache_%=31.5;Cache_num=895;Scan_per_sec=9.5; Clam_num=2;Scan_%=66.7;Scan_num=2552;Cache_%=33.3;Cache_num=1273;Scan_per_sec=12.8; Clam_num:3 Scan_%:67.3 Scan_num:6474 Cache_%:32.7 Cache_num:3143 Scan/sec:32.1 | Clam_num=3;Scan_%=67.3;Scan_num=6474;Cache_%=32.7;Cache_num=3143;Scan_per_sec=32.1; As you can see, the parser suddenly decides that for Clam_num 3 it's going to insert both the status and performance data into the DS of what should only be performance data. When I look at the XML file, the DS that should just contain the value "3" for Clam_num actually contains the entire string of: "Clam_num:3 Scan_%:67.3 Scan_num:6474 Cache_%:32.7 Cache_num:3143 Scan/sec:32.1 | Clam_num=3;Scan_%=67.3;Scan_num=6474;Cache_%=32.7;Cache_num=3143;Scan_per_sec=32.1;" Even stranger, the DS values that follow resume correctly and contain what they should. e.g. The scan_% value for Clam 3 is correct, the Scan_num value is correct, etc. Am I missing something here or is this the twilight zone?
