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 0000000..7086686 --- /dev/null +++ b/collectors/python.d.plugin/logind/logind.chart.py @@ -0,0 +1,85 @@ +# -*- coding: utf-8 -*- +# Description: logind netdata python.d module +# Author: Austin S.
