Combines bpftrace, Performance Co‑Pilot and Grafana to run bpftrace scripts from the browser: a PCP PMDA starts BPFtrace on demand and stops it when panels close, PMProxy exposes metrics via REST on port 44322, and a Grafana plugin renders heatmaps, flame graphs and tables. Examples: vfs_read bytes shown as a live heatmap, CPU run‑queue latency histogram in microsecond buckets, TCP connect events exported as CSV and limited to 10 table rows. Provides a container with all deps on port 3000; requires patched bpftrace for newer kernels.
