+# collectd-systemd
+
+collectd-systemd is a collectd plugin to read some basic stats from
+systemd.  Currently, it reads how many units are in each state
+(inactive/activating/active/reloading/deactivating/failed), how many
+jobs have ever been installed, how many jobs are currently queued, and
+how many jobs have failed.
+
+# Dependencies
+
+ - systemd (obviously)
+ - collectd (obviously), compiled with Python support
+ - python (2 or 3; whichever version collectd was compiled with)
+ - python-dbus
+
+# Installation
+
+The standard GNU process (`./configure --prefix=/usr && make && sudo make install`),
+but instead of running `./configure`, just edit `config.mk` to taste.
+
+To enable it, add `Include "/usr/share/collectd/systemd.conf"` (or
+similar, based on your configured file paths) to your `collectd.conf`.

 # This should be both valid Python 2 and 3, as the collectd Python
 # plugin can be either Python 2 or 3 (decided at compile time).
 #
 # Oddly, the Arch 'collectd' package chose Python 2, despite using
 # Python 3 as the default system Python.  I assume they have a good
 # reason for it, though I can't find it discussed anywhere.
