4. Pre-requisites
• We need to install an open source WMI Client, as previous versions
(Ubuntu packaged .deb versions of WMI-Client, for example) do not work
with newer versions of Windows (2008, 7, etc).
• We also need to install the check_wmi_plus.pl script, which requires some
configuration, along with some modules via CPAN/APT.

5. Background Information
• In the example environment used for this setup, we have a Ubuntu 10.04
x64 server, however aside from the plugins/packages downloaded by APT
(which can be downloaded via alternatives package managers) the steps
are nearly identical.

7. Installation
• Firstly, we must install some pre-requisite packages on our server. These
are “gcc”, “automake” and “DateTime.pm” (A perl module required):
sudo apt-get install autoconf gcc libdatetime-perl
• Once done, we will now install the underlying WMI client. Firstly, change
directory to /home/user (or wherever you would like the config work to be
done, however this is all relative).

8. Installation
• Once done, we will now install the underlying WMI client. Firstly, change
directory to /home/user (or wherever you would like the config work to be
done, however this is all relative).
• Secondly, download the source from the link below and extract:
wget http://dev.zenoss.org/svn/trunk/inst/externallibs/wmi-1.3.16.tar.bz2
bunzip2 wmi-1.3.16.tar.bz2
tar -xvf wmi-1.3.16.tar cd wmi-1.3.16/

9. Installation
• Now we are in the wmi folder, we will need to set the location of our
“../bin/python” directory; in our case using Ubuntu, it is in /usr, so:
export ZENHOME=/usr
• This tells the program to look for /bin/python in /usr, i.e. /usr/bin/python
(the fqdn).
• Next, we will need to edit “GNUmakefile” as below, and find and comment
out / delete the line “USE_BREAKPAD=1”:
nano GNUmakefile
And comment out the line, so it looks like “#USE_BREAKPAD=1”.

10. Installation
• Next, we need to run “make” and the compilation will begin, this can take
up to 10 minutes.
• Then we will need to move the newly created wmic into /bin, using the
command below:
cp /home/ubuntu/wmi/wmi-1.3.16/Samba/source/bin/wmic /bin
• Next we will need to install some Perl modules required:
perl -MCPAN -e shell
cpan>o conf urllist http://ppm.activestate.com/CPAN http://cpan.perl.org
cpan>o conf commit cpan>o conf prerequisites_policy follow
cpan>o conf commit cpan>install Config::IniFiles

11. Installation
• Once done, we will next need to download the check_wmi_plus plugin
and compile. To do this, we must first download and extract using the
commands:
wget http://edcint.co.nz/checkwmiplus/sites/default/files/check_wmi_plus.v1.52.tar.gz
tar -zxvf check_wmi_plus.v1.52.tar.gz
• You should “cd ….” again to a suitable location to extract and work on the
plugin. Once extracted, we will need to copy/rename the sample
config, so we have a copy we are working on, as below:
cp check_wmi_plus.conf.sample check_wmi_plus.conf
• Once done, we will need to edit the new config using nano/vim etc:
nano check_wmi_plus.conf

12. Installation
• There are a few items we need to edit:
• $base_dir="home/ubuntu/wmi/”; << This needs to be the folder where
we extracted wmi, i.e. where the folder “wmi-1.3.16” lives.
• $wmic_command="/bin/wmic"; << This should be ok if you followed
instructions, as this is where we moved our newly compiled “wmic” to.
• $wmi_ini_file='/home/ubuntu/wmi/check_wmi_plus.d/check_wmi_plus.i
ni'; << This should be where the “check_wmi_plus.ini” file lives, normally
within the extracted “check_wmi_plus.d” folder.
• $wmi_ini_dir="/home/ubuntu/wmi/check_wmi_plus.d/" << As above.
• Once this file is edited and tailored per your system/install, we should be
almost ready to test. Finally, we need to edit the plugin itself and edit the
value, so:
nano check_wmi_plus.pl my $conf_file='/home/ubuntu/wmi/check_wmi_plus.conf';
• To point to our newly created/edited config file at /home/ubuntu/wmi/

13. Installation
• So now we should have the wmic program downloaded and compiled, the
required Perl modules downloaded and installed, and the check_wmi_plus
plugin downloaded, compiled and customised.
• We can test our plugin against a WMI enabled Windows machine (WMI
enabled means someone has gone into the server, “start > run >
services.msc (enter) >” scrolled down to “WMI Performance Adapter” and
“started” it.
• To test, run a command similar to below:
root@devvm:/home/ubuntu/wmi# ./check_wmi_plus.pl -H 192.168.11.107 -u root -p opsview -m checkcpu
OK (Sample Period 489 sec) - Average CPU Utilisation 6.69%|'Avg CPU Utilisation'=6.69%;
• Where “-H” is for host, “-u” is for user, and “-p” is for password. “-m” is
the mode (“-s” is where we add the sub-mode). If the command
works, you should see an output as above. If you do, congratulations your
Opsview Server is now monitoring without an agent!
