Ganglia is a popular distributed monitoring system that can be used to monitor clusters, networks, and servers in real-time. In this tutorial, we will go through the steps of installing Ganglia on OpenBSD.
Before we can start installing Ganglia, we need to meet some prerequisites. These include:
Ganglia requires several dependencies that must be installed before we can proceed. Run the following command to install the dependencies:
$ doas pkg_add -i bash net-snmp net-snmp-perl perl rrdtool
Next, we need to download the latest stable version of Ganglia from the official website. Run the following command to download the source code:
$ ftp http://downloads.sourceforge.net/project/ganglia/ganglia%20monitoring%20core/3.7.2/ganglia-3.7.2.tar.gz
Once the download is complete, extract the tarball using the following command:
$ tar zxvf ganglia-3.7.2.tar.gz
This will extract the source code into a directory named ganglia-3.7.2
.
The next step is to build and install Ganglia. Navigate to the ganglia-3.7.2
directory and run the following commands:
$ cd ganglia-3.7.2
$ ./configure --with-gmetad --with-libpcre
$ make
$ doas make install
This will configure, build, and install Ganglia with gmetad and libpcre support.
After successfully installing Ganglia, we need to configure it to monitor our systems. Navigate to the /usr/local/etc/ganglia
directory and edit the gmond.conf
file using your preferred text editor.
In this file, make sure to update the following values:
Now we can start the Ganglia services. Run the following command to start the gmond and gmetad services:
$ doas /usr/local/etc/rc.d/gmond start
$ doas /usr/local/etc/rc.d/gmetad start
In this tutorial, we have gone through the steps of installing and configuring Ganglia on OpenBSD to monitor our systems. By following these steps, you should now have a working installation of Ganglia that can be used to monitor the performance of your systems.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
