+              In order for the collector to work, you need to add the `netdata` user to the `varnish` user group, so that it can execute the `varnishstat` tool:
+              
+              ```
+              usermod -aG varnish netdata

+            * Global variables
+            * One or more JOBS that can define multiple different instances to monitor.
+            
+            The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
+            
+            Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
+            
+            Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.
