A status API exists, which dumps some basic diagnostic and statistical information, as well as basic information about the underlying Raft node. Assuming the rqlite node is started with default settings, node status is available like so:
curl localhost:4001/status?prettyThe use of the URL param pretty is optional, and results in pretty-printed JSON responses.
rqlite also exports expvar information. The standard, and some custom information, is exposed. This data can be retrieved like so:
curl localhost:4001/debug/vars
