How to Install Ganglia on Clear Linux Latest

Ganglia is a scalable, distributed monitoring system for high-performance computing systems, networks, and clusters. In this tutorial, we will walk through the steps of installing Ganglia on Clear Linux Latest.

Prerequisites

Before we begin, make sure you have the following:

• A Clear Linux Latest system
• Root access or sudo privileges
• Internet access

Step 1: Installing Dependencies

Before installing Ganglia, we need to install some dependencies. Open a terminal and run the following command:

sudo swupd bundle-add development-tools network-basic

This command installs the necessary tools and libraries to build and run Ganglia.

Step 2: Downloading Ganglia

Go to the Ganglia website (http://ganglia.sourceforge.net/) and download the latest stable version of Ganglia. After downloading, extract the archive to a directory of your choice. For example:

tar -xzf ganglia-3.7.2.tar.gz
cd ganglia-3.7.2

Step 3: Building Ganglia

Now that we have downloaded and extracted Ganglia, we need to build it. Ganglia uses autotools to configure itself, so we need to run the following command:

./configure --with-gmetad --prefix=/usr --sysconfdir=/etc/ganglia

This command configures Ganglia with the gmetad daemon and installs it in the /usr directory. The --sysconfdir parameter specifies the location of the configuration file.

After configuring, run the following command to build and install Ganglia:

make
sudo make install

Step 4: Configuring Ganglia

Now that we have installed Ganglia, we need to configure it. First, copy the sample gmond.conf and gmetad.conf files to the sysconfdir directory we specified earlier:

sudo cp gmond/gmond.conf.example /etc/ganglia/gmond.conf
sudo cp gmetad/gmetad.conf.example /etc/ganglia/gmetad.conf

Next, edit the gmond.conf file and uncomment the following lines:

udp_send_channel {
  host = 127.0.0.1
  port = 8649
  ttl = 1
}

These lines allow Ganglia to send monitoring data to itself.

Edit the gmetad.conf file and uncomment the following lines:

data_source "my cluster" localhost

This line specifies the data source for Ganglia, which in this case is the localhost.

Step 5: Starting Ganglia

Now that we have configured Ganglia, we need to start it. Run the following commands:

sudo systemctl enable gmond.service
sudo systemctl start gmond.service
sudo systemctl enable gmetad.service
sudo systemctl start gmetad.service

These commands enable and start the gmond and gmetad services.

Step 6: Accessing the Ganglia Web Interface

Finally, we can access the Ganglia web interface by opening a web browser and navigating to http://localhost/ganglia/. You should see the Ganglia web interface with monitoring data for the local cluster.

Congratulations! You have successfully installed and configured Ganglia on Clear Linux Latest.

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!
