+To retrieve this information, the module must
+have enough permissions to scan the Varnish management directory and
+read files located in it. This directory is normally named
+\fB/var/lib/varnish/\fIHOSTNAME\fB/_.vsm_mgt\fR, where \fIHOSTNAME\fR
+stands for the server's hostname. Unless
+.BR snmpd (8)
+is run as root, special measures should be undertaken in order to
+grant access rights. For example, if the daemon runs as user
+\fBsnmp\fR, running the following two commands after starting
+\fBvarnishd\fR will do the trick:
