Time for action – installing the CactiWMI add-on – Part 1

1. Logon to your Cacti server.

2. Change to the /tmp directory:

   cd /tmp
   

3. Download the Cacti WMI add-on (http://forums.cacti.net/download/file.php?id=16949):

   wget –O CactiWMI.tgz 
   

4. Extract the files from the archive:

   tar -xzvf CactiWMI.tgz
   

5. Change into the created directory:

   cd 0.0.6.r101/
   

6. Run the following commands. They will copy the wmi script to the correct Cacti path as well as create the necessary directories. The chmod commands change the permissions of the files so Cacti is able to perform WMI calls:

   cp wmi.php /var/www/html/cacti/scripts
   mkdir -p /etc/cacti
   mkdir -p /var/log/cacti/wmi
   chown cactiuser:cactiuser /etc/cacti -R
   chown cactiuser:cactiuser /var/log/cacti/wmi -R
   chmod 700 /etc/cacti -R
   chmod 700 /var/log/cacti/wmi –R
   

7. Now create the auth.conf file which will contain your WMI user credentials:

   vi /etc/cacti/cactiwmi.pw
   

8. The file should have the following format:

   username=<your username>
   password=<your password>
   domain...
