Using bpftrace with Performance Co-Pilot & Grafana

In this talk the audience will learn how to use bpftrace, Performance Co-Pilot (PCP) and Grafana to get live, on-demand system metrics in the browser.
Attendees will learn how to setup the required components and how to write bpftrace scripts to gather system internals.

Previously bpftrace scripts had to be run by SSHing into a server, executing them and interpreting the console output. With PCP and Grafana, we can have visualizations of bpftrace scripts, for example we can visualize the return value of the vfs_read kernel function (amount of bytes written) in a live heatmap, capture stack traces and display them as flame graphs, and trace network functions and display them in a table.
