+title: "Dovecot monitoring with Netdata"

+-->
+
+# 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**
+
+ - voluntary
+ - involuntary
+
+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 Netdata [config
+directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
+
+```bash
+cd /etc/netdata # Replace this path with your Netdata config directory, 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`

+# netdata python.d.plugin configuration for dovecot
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+# - global variables
+# - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+# name: myname # the JOB's name as it will appear at the
+# # dashboard (by default is the job_name)
+# # JOBs sharing a name are mutually exclusive
+# update_every: 1 # the JOB's data collection frequency
+# priority: 60000 # the JOB's order on the dashboard
+# penalty: yes # the JOB's penalty
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, dovecot also supports the following:
+#
+# socket: 'path/to/dovecot/stats'
+#
+# or
+# host: 'IP or HOSTNAME' # the host to connect to
+# port: PORT # the port to connect to
+#
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
