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' +``` + +### 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. + +--- diff --git a/collectors/python.d.plugin/logind/logind.chart.py b/collectors/python.d.plugin/logind/logind.chart.py new file mode 100644 index 000000000..bfc486c7f --- /dev/null +++ b/collectors/python.d.plugin/logind/logind.chart.py @@ -0,0 +1,79 @@ +# -*- coding: utf-8 -*- +# Description: logind netdata python.d module +# Author: Austin S.
