 By action, we mean all shell command line. For example, if you want to execute the foo.py script if the last 5 minutes load are critical then add the action line to the Glances configuration file:
 
-  [load]
-  critical=5.0
-  critical_action=python /path/to/foo.py
+.. code-block::
+
+    [load]
+    critical=5.0
+    critical_action=python /path/to/foo.py
 
 All the stats are available in the command line through the use of the {{mustache}} syntax. Another example to create a log file containing used vs total disk space if a space trigger warning is reached:
 
-  [fs]
-  warning=70
-  warning_action=echo {{mnt_point}} {{used}}/{{size}} > /tmp/fs.alert
+.. code-block::
+
+    [fs]
+    warning=70
+    warning_action=echo {{mnt_point}} {{used}}/{{size}} > /tmp/fs.alert
 
 *Note*: You can use all the stats for the current plugin (see https://github.com/nicolargo/glances/wiki/The-Glances-2.x-API-How-to for the stats list)
