nagios流量监控的三种方法
[*]-bash-3.2# /usr/local/nagios/libexec/check_traffic.sh -V 1 -C nagios -H localhost -I 2 -w 12,30 -c 15,35 -M -b

3.使用nagios自带的check_mrtgtraf来监控流量，前提是系统上面已经安装了mrtg了。让nagios来读取mrtg的流量日志数据，check_mrtgtraf -h
Options:
-h, --help
Print detailed help screen
-V, --version
Print version information
-F, --filename=STRING
File to read log from
-e, --expires=INTEGER
Minutes after which log expires
-a, --aggregation=(AVG|MAX)
Test average or maximum
-w, --warning
Warning threshold pair ,
-c, --critical
Critical threshold pair ,
define command{
command_name traffic_average
command_line /usr/lib/nagios/plugins/check_mrtgtraf '$ARG1$' 10 AVG '$ARG2$' '$ARG
3$' '$ARG4$' '$ARG5$'
}
值得注意的是这里的-F参数后面的日志文件是mrtg获取的日志数据的文件名
