# Dovecot monitoring with Netdata

Provides statistics information from Dovecot server.

Statistics are taken from dovecot socket by executing `EXPORT global` command.
More information about dovecot stats can be found on [project wiki page.](http://wiki2.dovecot.org/Statistics)

Module isn't compatible with new statistic api (v2.3), but you are still able to use the module with Dovecot v2.3
by following [upgrading steps.](https://wiki2.dovecot.org/Upgrading/2.3).

**Requirement:**
Dovecot UNIX socket with R/W permissions for user `netdata` or Dovecot with configured TCP/IP socket.

Module gives information with following charts:

1.  **sessions**

-   active sessions

2.  **logins**

-   logins

3.  **commands** - number of IMAP commands

-   commands

4.  **Faults**

-   minor
    -   major

5.  **Context Switches**

-   volountary
    -   involountary

6.  **disk** in bytes/s

-   read
    -   write

7.  **bytes** in bytes/s

-   read
    -   write

8.  **number of syscalls** in syscalls/s

-   read
    -   write

9.  **lookups** - number of lookups per second

-   path
    -   attr

10. **hits** - number of cache hits

-   hits

11. **attempts** - authorization attempts

-   success
    -   failure

12. **cache** - cached authorization hits

-   hit
    -   miss

## Configuration

Edit the `python.d/dovecot.conf` configuration file using `edit-config` from the your agent's [config
directory](/docs/step-by-step/step-04.md#find-your-netdataconf-file), which is typically at `/etc/netdata`.

```bash
cd /etc/netdata   # Replace this path with your Netdata config directory, if different, if different
sudo ./edit-config python.d/dovecot.conf
```

Sample:

```yaml
localtcpip:
  name     : 'local'
  host     : '127.0.0.1'
  port     : 24242

localsocket:
  name     : 'local'
  socket   : '/var/run/dovecot/stats'
```

If no configuration is given, module will attempt to connect to dovecot using unix socket localized in `/var/run/dovecot/stats`
