Status and Diagnostics API

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?pretty

The use of the URL param pretty is optional, and results in pretty-printed JSON responses.

expvar support

rqlite also exports expvar information. The standard expvar information, as well as some custom information, is exposed. This data can be retrieved like so (assuming the node is started in its default configuration):

curl localhost:4001/debug/vars

pprof support

pprof information is available by default and can be retrieved as follows:

curl localhost:4001/debug/pprof/cmdline
curl localhost:4001/debug/pprof/profile
curl localhost:4001/debug/pprof/symbol
