Memory Debugging via Heaptrack

The heaptrack command accepts a binary file + args. After stopping it via ctrl c you can inspect the dump it produces with heaptrack_gui <dump file>.

Running In a Deployment

Edit universal/Dockerfile to install heaptrack via apt and change the entrypoint to ["heaptrack"] and command to ["/usr/bin/rivet-engine start"].

While the engine is still running (or after it stops), you can copy the heaptrack to local disk via kubectl cp rivet-engine/<pod name>:heaptrack.rivet-engine.7.gz local-heaptrack.7.gz. Finally run heaptrack_gui local-heaptrack.7.gz.
