+Check deb-lastactivity
+======================
+
+Overview
+--------
+
+Checks the timespan since the last package manager activity, for example due to an apt install/update.
+
+
+Fact Sheet
+----------
+
+.. csv-table::
+    :widths: 30, 70
+    
+    "Check Plugin Download",                "https://github.com/Linuxfabrik/monitoring-plugins/tree/main/check-plugins/deb-lastactivity"
+    "Check Interval Recommendation",        "Once a day"
+    "Can be called without parameters",     "Yes"
+    "Compiled for",                         "Linux"
+
+
+Help
+----
+
+.. code-block:: text
+
+    usage: deb-lastactivity [-h] [-V] [-c CRIT] [-w WARN]
+
+    Checks the timespan since the last package manager activity, for example due
+    to an apt install/update.
+
+    options:
+      -h, --help            show this help message and exit
+      -V, --version         show program's version number and exit
+      -c CRIT, --critical CRIT
+                            Set the critical threshold (in days). Default: 365
+      -w WARN, --warning WARN
+                            Set the warning threshold (in days). Default: 90
+
+
+Usage Examples
+--------------
+
+.. code-block:: bash
+
+    ./deb-lastactivity --warning 90 --critical 365
+    
+Output:
+
+.. code-block:: text
+
+    Last package manager activity is 5M 2W ago [WARNING] (thresholds 90D/365D).
+
+
+States
+------
+
+* WARN or CRIT if last activity is above a given threshold.
