Status and Diagnostics API
A status API exists, which dumps some 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.
You can also request the same status information via the CLI:
$ rqlite
127.0.0.1:4001> .status
runtime:
GOARCH: amd64
GOMAXPROCS: 8
GOOS: linux
numCPU: 8

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
You can also request the same expvar information via the CLI:
$ rqlite
127.0.0.1:4001> .expvar
