tcollector is a lightweight, open-source monitoring agent that can collect metrics from various sources and send them to OpenTSDB. In this tutorial, we will guide you through the process of installing tcollector on Fedora Server Latest.
Before you begin, you should have:
sudo dnf update -y
tcollector requires several packages to be installed. Use the following command to install them:
sudo dnf install -y python3-pip make gcc openssl-devel
Use the following command to install tcollector using pip:
sudo pip3 install tcollector
To configure tcollector, create a configuration file at /etc/tcollector.conf using the following command:
sudo nano /etc/tcollector.conf
Add the following values to the configuration file:
{
"host": "<your-tcollector-host>",
"interval": 60,
"collectors": [
{
"module": "cpu",
"path": "/proc/cpuinfo",
"args": "",
"timeout": 3,
"enabled": true
},
{
"module": "loadavg",
"path": "/proc/loadavg",
"args": "",
"timeout": 3,
"enabled": true
},
{
"module": "meminfo",
"path": "/proc/meminfo",
"args": "",
"timeout": 3,
"enabled": true
}
]
}
In this example configuration file, three collectors are being used to collect CPU, Load Average, and Memory information. You can add or remove collectors as per your requirements.
Use the following command to start tcollector:
sudo service tcollector start
You can check the status of tcollector using the following command:
sudo service tcollector status
The output of this command should show that tcollector is running.
Congratulations! You have successfully installed and configured tcollector on Fedora Server Latest. You can now use it to collect and send metrics to OpenTSDB.
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!
