<div>Have you tested the command from the command line?</div>
<div> </div>
<div>before implementing a WMI CHeck in NC_Net it should be tested via the command line, to make sure you get the desired results.</div>
<div> </div>
<div>Read the help Files.</div>
<div>./check_nt --help=WMICHECK -should be run from command line it returns mutiple lines</div>
<div>./check_nt --help=WMICOUNTER -can use -c and -w against query</div>
<div>./check_nt --help=WMICAT - should be used in nagios instead of WMICHECK</div>
<div>and the Readme from NC_Net</div>
<div> </div>
<div>This command will not work.. the syntax is wrong and it does not define a Query</div>
<div><font size="2">command_line $USER1$check_nt -H $HOSTADDRESS$ -v WMICHECK -l "cimv2/win32_logicaldrive"</font></div>
<div>It should be win32_logicaldisk and it needs to have a select part of the statement like * thus the following should be used instead (all the following are parsed to the same query)</div>
<div>-l "cimv2^*^win32_logicaldisk"</div>
<div>-l "cimv2^select * from win32_logicaldisk" </div>
<div>
<div>-l "cimv2&*&win32_logicaldisk"</div>
<div>-l "cimv2&select * from win32_logicaldisk" </div></div>
<div> </div>
<div>as for the command:</div>
<div><font size="2">command_line /usr/local/nagios/libexec/check_nt -H $HOSTADDRESS$ -v WMICHECK -l "cimv2^select name,freespace,deviceid,status from win32_DiskDrive"</font></div>
<div><font size="2">win32_DiskDrive does not have Freespace remove it and it should work:</font></div>
<div>-l "cimv2^select name,deviceid,status from win32_diskdrive"</div>
<div> </div>
<div>As for the command:</div>
<div>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">command_line $USER$/check_nt -H $HOSTADDRESS$ -v WMICHECK -l "cimv2^select DeviceID,Status from win32_DiskDrive"</span></font>
</p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">THis ran OK on my system? </span></font></p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"></span></font> </p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">steps to resolve the issue:</span></font></p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Make sure the Check_Nt works from the command line.</span></font></p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Make sure this Check_nt is in the libexec directory of Nagios.</span></font></p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Check the permissions of check_nt to make sure user Nagios can run it.</span></font></p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">For the most part Check_nt should always return a 0,1,2,3 so it may be a permission or missing file issue.</span></font></p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Also WMICHECK is really meant to be run from the command line because it returns multiple lines and NAgios only resolves the first line of the output.
</span></font></p>
<p><font face="Arial" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">WMICAT should be used instead of WMICHECK in nagios.</span></font></p></div>
<div>A example of checking all drives freespace and then returning a critical if any drive has less than 1Gig of space is: (Make sure to exclude all drives that do not implement freespace like floppy and CR-Roms.)</div>
<div> -v WMICOUNTER -l "cimv2^select freespace from win32_logicaldisk where name != 'a:' " -c 1000000000<br> </div>
<div>for more information and on WMI query see <a href="http://msdn.com">msdn.com</a>:</div>
<div><a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/wql_sql_for_wmi.asp">http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/wql_sql_for_wmi.asp</a></div>
<div> </div>
<div>NC_Net has been tested for use mostly with simple select statement, thus all queries should be checked using the command line before implementing in nagios.</div>
<div> </div>
<div>IF WMICAT and WMICOUNTER do not meed your nagios needs, Then WMICHECK can be used but should be invoked form a wrapper script that will parse the data into a more appropriate format for Nagios.</div>
<div> </div>
<div> </div>
<div>I hope this helps clarifying some of the usage of WMI with NC_Net</div>
