Performance Co-Pilot (PCP) is an open-source system monitoring and performance management toolkit. It provides a set of powerful tools for collecting, processing, and presenting performance data in a user-friendly manner. In this tutorial, we will guide you through the steps to install PCP on Debian Latest.
Before we start with the installation process, make sure that you have a Debian Latest system with root privileges.
First, we need to update the Debian system to ensure that all packages are up-to-date. To do this, open the terminal and run the following command:
sudo apt update && sudo apt upgrade -y
Once the system update is complete, we can move on to install PCP. To do this, run the following command:
sudo apt install pcp -y
This will install the PCP package along with its dependencies.
After the installation is complete, we can verify that PCP is installed and running by checking the status of the pmcd service:
sudo systemctl status pmcd
If the output shows the status as "active (running)", then PCP is successfully installed.
In order to collect and monitor various aspects of the system, we need to configure the Performance Metrics Domain Agents (PMDA). By default, PCP comes with a number of PMDAs installed. To activate a specific PMDA, you can run the following command:
sudo pmcd -R pmda_name
Here, pmda_name refers to the name of the PMDA that you want to activate.
Once the PMDAs are activated, we can start collecting performance metrics from the system. To access these metrics, we can use the pminfo and pmval commands.
For example, if we want to check the CPU usage of the system, we can run:
pminfo kernel.all.cpu.user
pmval kernel.all.cpu.user
This will show us the current CPU usage of the system.
In this tutorial, we have shown you how to install Performance Co-Pilot (PCP) on Debian Latest. We have also demonstrated how to activate PMDAs and access performance metrics from the system. With PCP, you have a powerful set of tools at your disposal to monitor and manage the performance of your system.
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!
