Some report correctly, others report a complete load of old tosh!!! I have tried 3 different versions of Windows OS, the version seems to make no odds. Doesn’t matter if 32 or 64 bit either. Some examples MY primary domain controller – Windows Server 2008 R2 (x64) – 8GB ram installed Output from the check appears correct: Memory usage: total:8205.64 Mb - used: 2902.96 Mb (35%) - free: 5302.67 Mb (65%) <table border="0" cellpadding="0"> <tbody> <tr> <td valign="top" style="padding:.75pt .75pt .75pt .75pt"></td> </tr> </tbody> </table> Another 2008 R2 (x64) server box (has SQL installed on it) – 12GB ram installed Output thinks its got 24GB: Memory usage: total:24573.16 Mb - used: 1796.71 Mb (7%) - free: 22776.45 Mb (93%) A Server 2003 Standard (x86) box (an internal test web server) – 512MB ram installed Output thinks its got over 1GB: Memory usage: total:1257.50 Mb - used: 333.30 Mb (27%) - free: 924.20 Mb (73%) A Server 2012 (x64) box (with HyperV installed) – 28GB ram installed Output thinks tis got 32GB: Memory usage: total:32500.80 Mb - used: 16709.37 Mb (51%) - free: 15791.43 Mb (49%) Anybody any ideas as to why check_nt is returning incorrect info. I know its incorrect but Nagios doesn’t so where exactly is it reading these values from? Thanks in advance for anybodies input.
