In this tutorial, we will go through the steps required to install tcollector on the latest version of Fedora CoreOS. Tcollector is a data collection framework that is used to collect system statistics and send them to OpenTSDB.
Before proceeding with the installation of tcollector, let's first make sure that all necessary packages are installed on the system.
Run the following command to install the required packages:
sudo dnf install -y git python3-setuptools gcc python3-devel
This will install the following packages:
Next, we will clone the tcollector repository from GitHub.
Run the following command to clone the repository:
sudo git clone https://github.com/opentsdb/tcollector.git /opt/tcollector
This will clone the tcollector repository to the /opt/tcollector directory on your system.
To install tcollector, navigate to the /opt/tcollector directory and run the following command:
sudo /opt/tcollector/build.sh
This will compile and install the necessary Python modules and scripts required by tcollector.
Once tcollector has been installed on your system, you need to configure it.
To configure tcollector, create a configuration file in the /opt/tcollector/collectors/ directory. For example, let's create a configuration file called cpu.cfg:
sudo nano /opt/tcollector/collectors/cpu.cfg
In this file, you can configure which metrics you want to collect and how often you want tcollector to send the data to OpenTSDB.
For example, to collect the CPU usage every 10 seconds, add the following line to your cpu.cfg file:
/etc/tcollector/collectors/0/60/cpu/percent="*/10 * * * * root /usr/bin/env python3 /opt/tcollector/collectors/cpu.py"
Note that the /etc/tcollector/collectors/0/60/cpu/percent is the metric name that will be used in OpenTSDB, and /opt/tcollector/collectors/cpu.py is the script that will collect the CPU usage.
Save and close the file when you are done.
To test tcollector, run the following command:
sudo /opt/tcollector/startstop start
This will start tcollector and begin collecting system statistics.
You can verify that tcollector is working by checking the logs in the /var/log/tcollector/ directory.
In this tutorial, we have shown you how to install tcollector on the latest version of Fedora CoreOS. By following the steps outlined in this tutorial, you should now be able to collect system statistics and send them to OpenTSDB using tcollector.
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!
