web access for a particular host group

一直在想怎么样让nagios分组,某些用户只能看到一部分数据.
其实nagios的cgi.cfg配置文件里面写得很清楚.

# GLOBAL HOST/SERVICE VIEW ACCESS
# These two options are comma-delimited lists of all usernames that
# can view information for all hosts and services that are being
# monitored.  By default, users can only view information
# for hosts or services that they are contacts for (unless you
# you choose to not use authorization). You may use an asterisk (*)
# to authorize any user who has authenticated to the web server.
