Profile Elasticsearch queries with an interactive flamegraph.
This was made as a very quick hack to help profile some ES queries. It is extremely particular to our setup, and I don't really care enough to generalise it, since it has served its purpose now. If you're trying to dig into something similar and can't afford the paid-for alternatives, try hacking around on this, or just read what I did and do it better!
- Interactive flamegraph of the query AST, as supplied by the Elasticsearch profile api (using this d3 library)
- List of the query "hits", with associated information
- Shard selector, to compare performance across shards
- Supports basic authentication. Because who would need anything more?
- Quick "hammer" function to flood the endpoint with requests as a small stress test. For masochists that like to DDoS themselves.
Move over, Jony Ive:
Get this, it's even interactive:
