<html> <head> <style> .hmmessage P { margin:0px; padding:0px } body.hmmessage { font-size: 10pt; font-family:Verdana } </style> </head> <body class='hmmessage'> I run the following from the command line from my Nagios box and it works like a champ... # ./libexec/check_nt -H server.domain.com -p 12489 -v COUNTER -l "<A href="file://\\Memory\\Available">\\Memory\\Available</A> MBytes","Available MBytes=%.2f" I put the appropriate info into my service check config and my command config files... it runs and I get a result... however the really strange part... the result value is very different. OUTPUT COMMANDLINE: Available MBytes=430.00 | 'Available MBytes=%.2f'=430.000000%;0.000000;0.000000; OUTPUT AS NAGIOS CHECK: Available MBytes=617480.00 | 'Available MBytes=%.2f'=617480.000000%;0.000000;0.000000; The value it retruns appears to be the USED MBytes maybe? Yes, this is against a server w/ ALOT of used memory. :-) Am I just missing something? -- Mat W. - <A href="mailto:lmw94002@hotmail.com">lmw94002@hotmail.com</A> <hr />Insert movie times and more without leaving Hotmail®. <a href='http://windowslive.com/Tutorial/Hotmail/QuickAdd?ocid=TXT_TAGLM_WL_HM_Tutorial_QuickAdd1_052009' target='_new'>See how.</a></body> </html>
