+# Systemd-Logind monitoring with Netdata
+
+Monitors active sessions, users, and seats tracked by `systemd-logind` or `elogind`.
+
+It provides the following charts:
+
+1. **Sessions** Tracks the total number of sessions.
+
+ - Graphical: Local graphical sessions (running X11, or Wayland, or something else).
+ - Console: Local console sessions.
+ - Remote: Remote sessions.
+
+2. **Users** Tracks total number of unique user logins of each type.
+
+ - Graphical
+ - Console
+ - Remote
+
+3. **Seats** Total number of seats in use.
+
+ - Seats
+
+## Enable the collector
+
+The `logind` collector is disabled by default. To enable it, use `edit-config` from the Netdata [config
+directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`, to edit the `python.d.conf` file.
+
+```bash
+cd /etc/netdata # Replace this path with your Netdata config directory, if different
+sudo ./edit-config python.d.conf
+```
+
+Change the value of the `logind` setting to `yes`. Save the file and restart the Netdata Agent with `sudo systemctl
+restart netdata`, or the appropriate method for your system, to finish enabling the `logind` collector.
+
+## Configuration
+
+This module needs no configuration. Just make sure the `netdata` user
+can run the `loginctl` command and get a session list without having to
+specify a path.
+
+This will work with any command that can output data in the _exact_
+same format as `loginctl list-sessions --no-legend`. If you have some
+other command you want to use that outputs data in this format, you can
+specify it using the `command` key like so:
+
+```yaml
+command: '/path/to/other/command'
+```
+
+Edit the `python.d/logind.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/logind.conf
+```
+
+## Notes
+
+- This module's ability to track logins is dependent on what PAM services
+ are configured to register sessions with logind. In particular, for
+ most systems, it will only track TTY logins, local desktop logins,
+ and logins through remote shell connections.
+
+- The users chart counts _usernames_ not UID's. This is potentially
+ important in configurations where multiple users have the same UID.
+
+- The users chart counts any given user name up to once for _each_ type
+ of login. So if the same user has a graphical and a console login on a
+ system, they will show up once in the graphical count, and once in the
+ console count.
+
+- Because the data collection process is rather expensive, this plugin
+ is currently disabled by default, and needs to be explicitly enabled in
+ `/etc/netdata/python.d.conf` before it will run.

+# netdata python.d.plugin configuration for logind
+#
+# 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
