+# Script for monitoring nginx Virtual host output traffic
+# 
+# Requierements: logtail awk
+# one unique access log file with $bytes_sent value for more accuracy
+# check http://wiki.nginx.org/NginxHttpLogModule
+#
+# Configuration Options (all options have defauts)
+# [nginx_vhost_traffic]
+#
+# Virtual host list
+# env.vhosts "example.com example.net example.org"
+# 
+# Log path
+# env.logdir = /var/log/nginx
+# env.flogfile = access.log 
+#
+# Position of the $bytes_sent in the access.log file
+# env.bparam 11
+#
+# Aggregate subdomains
+# ex: example.com will match www.example.com, webmail.example.com and *example.com 
+# BUG: will also match also www.bad-example.com
+# env.aggregate true #change to false to disable aggregation 
+#
+# To report bugs, improvements or get updates
