Requirements:
Nagios Version 3
Installation:
ndoutils ( Optional, only needed for checkhistory, alerthistory, commandhistory)
I will not go through the ndoUtils installation details. Here is a good link for NdoUtils installation guideline. http://www.monitoringexchange.org/cgi-bin/page.cgi?g=Detailed%2F1574.html;d=1
However I will suggest set data_processing_options to 33438717 in ndomod.cfg file, which gave me the best performance.
Nagios Object:
You can get Nagios-object module from the following link.
http://search.cpan.org/~duncs/Nagios-Object-0.21.8/lib/Nagios/Object.pm
ncom:
1)First we need to add the authentication information to the script.
a) untar using gzip -dc ncom -0.5.tar.gz | tar -xof -
b) cd into newly created directory and modify the following line of ncom file
my $dbhostname=''; ###this is the host where ndoutils database resides
my $database=''; ## name of the ndoUtils database
my $login_username=''; ###username for database
my $password=''; ###password for database.
2) Upon making the modification one can manually copy the file to /usr/bin or /usr/local/bin directory. I also added a spec file so one can create a rpm from this. However to use the spec file to create rpm, you must re-tar the directory using tar -czvf ncom -0.5.tar.gz ncom-0.5.
Hope this works out for you. Feel free to contact me if you have any issue with this.
