Performance Co-Pilot (PCP) is an open source system performance monitoring framework for Linux-based operating systems. It provides a flexible and extensible system for observing, visualizing, and analyzing performance data in real-time. This tutorial will guide you through the process of installing PCP on nixOS Latest.
Before proceeding with the installation, make sure you have a nixOS Latest installation up and running. You should also have Internet access and administrative privileges.
The first step is to install PCP from the nix package manager. Open the terminal and run the following command:
sudo nix-env -iA nixos.pcp
This command will install the latest version of PCP from the nix package repository.
Once the installation is complete, you can verify PCP is installed by running the following command:
pminfo
If PCP is installed correctly, the output should be a list of available metrics.
PCP consists of several services that need to be started to function correctly. To start the services, run the following command:
sudo systemctl start pmcd pmlogger pmie
This command will start the Performance Metrics Collector Daemon (pmcd), the Performance Metrics Logger (pmlogger), and the Performance Metrics Interpreter/Exporter (pmie) services.
By default, PCP is configured to collect system performance data every 20 seconds. You can modify the configuration settings by editing the /etc/pcp/pmcd/pmcd.conf file.
You can also start and stop PCP services using the systemctl command. For example, to stop the pcie service, run the following command:
sudo systemctl stop pmie
Congratulations! You have successfully installed Performance Co-Pilot on nixOS Latest. You can now use PCP to monitor your system performance in real-time. If you encounter any issues, refer to the official PCP documentation or seek help from the nixOS community.
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!
