Make and more
The installation of PNP is controlled by makefiles. The system is analyzed after invocation of ./configure and the detected values are tranferred to makefiles.
Please unpack PNP as user root:
wget http://sourceforge.net/projects/pnp4nagios/files/PNP-0.6/pnp4nagios-0.6.16.tar.gz/download tar -xvzf pnp4nagios-0.6.16.tar.gz cd pnp4nagios-0.6.16
By default rrdtool is not included in CentOS. You may need to install it for monitoringpurpose. You can either use source to compile or install using rpm.
To install using rpm all you need is following two commands.
For 32 bit systems
rpm -ivh http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el5.rf.i386.rpm
For 64 bit systems
rpm -ivh http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
yum install rrdtool -y
./configure is to be called from the directory pnp4nagios.
Note: Without specifying any options user and group will be “nagios”. If you have different values then please use the parameters ”–with-nagios-user” and ”–with-nagios-group”, respectively. Using Icinga the call might be
./configure --with-nagios-user=icinga --with-nagios-group=icinga
Some lines run across the screen. The output at the end is important.
