Timeturner lets you view detailed system snapshots for the recent past. It helps you dig into system problems by answering questions like What process was using all that memory? or What were all those queries that started running?

Timeturner accepts snapshots through a simple REST API, stores them in a SQLite database, and serves them through a web interface.

Simply PUT your snapshot data as a CSV (with a header row) to /<date>/<time>/<hostname>/<title>, e.g.,

curl -X PUT --data-binary "name,quote
steve,hello world
howard,goodbye world
" 'http://localhost:8080/2013-10-05/15:32:44/stevebox/quotes/'
