Hi,
I'm using NSclient (1.0.7.1) and check_nt (nagios-plugins 1.3.0 / 1.7) in conjunction with a shell script to pull some W2k-perfcounters from several servers into MRTG which work fine so far for Memory,SMTP-Messages,PagePool etc. Just to point out it's working overall fine.. Also using from within Nagios to monitor works fine.
Now I've added the following counters which return me somewhat strange values:
"\\PhysicalDisk(_Total)\\Avg. Disk Queue Length" : polled with check_nt it's *always* 0, in perfmon it isn't.
"\\PhysicalDisk(_Total)\\Disk Read Bytes/sec" / "\\PhysicalDisk(_Total)\\Disk Write Bytes/sec":
the values I receive are very "static" and *very* strange. In perfmon I see a normal graph showing some movement, so the values within perfmon are correct. An example to illustrate:
Values from Perfmon "\\PhysicalDisk(_Total)\\Disk Write Bytes/sec"
197562,763446308 15337,7748891304 37833,0113271332 227493,179856569 225081,310079066 197605,281148608 14067,0434390914 12074,8110884988 185230,215176143 312124,651960133 128784,648122873 104239,2056829 93099,405679069 158402,832409301 320800,643613903 225597,324605396 81592,1992627104
So they're variying as I'd expect.
when using check_nt to poll via NSClient from the same server I get (only changing a few bytes when monitoring for several hours):
169915,169914,169913,169912,169912,169911,169910,169909,169909,169908,169907,169906,169905,169905,169904,169903
Also, when there comes load to the disks, nothing is changing on these counters..
I've tested with different servers and some other counters on the same machines work fine, anybody has an idea what this is caused by ?
thanks,
Michael
