# 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:

```bash
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](http://godoc.org/pkg/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):

```bash
curl localhost:4001/debug/vars
```

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

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