Profiling Fission with Pprof

Fission uses net/pprof for profiling the code across Fission components. It would be helpful in identifying performance bottlenecks.

To enable profiling, just set pprof.enabled to true while installing Fission helm chart.

Pprof data of component pod

Do port forwarding to port 6060 of the pod,

kubectl port-forward pod/executor-668dfd7c89-2b2ff 6060:6060

Run different commands to get or analyze pprof data,

go tool pprof http://localhost:6060/debug/pprof/flamegraph

go tool pprof http://localhost:6060/debug/pprof/profile\?seconds\=60

You can also analyze with binary to get correct references of source,

# Download binary from pod
kubectl cp fission/executor-668dfd7c89-2b2ff:/fission-bundle fission-bundle

go tool pprof -http ":49816" fission-bundle http://localhost:49513/debug/pprof

You can also download pprof data and visualize/analyze with different compatible tools.
