• -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
  
• /usr/local/nagios/libexec/check_traffic.sh: line 449: bc: command not found
  
• /usr/local/nagios/libexec/check_traffic.sh: line 454: bc: command not found
  
• /usr/local/nagios/libexec/check_traffic.sh: line 457: bc: command not found
  
• /usr/local/nagios/libexec/check_traffic.sh: line 458: bc: command not found
  
• /usr/local/nagios/libexec/check_traffic.sh: line 461: [: too many arguments
  
• /usr/local/nagios/libexec/check_traffic.sh: line 576: bc: command not found
  
• /usr/local/nagios/libexec/check_traffic.sh: line 577: bc: command not found
  
• Unknown - Can not found data in the history data file. Please to check the file /var/tmp/check_traffic_localhost_2.hist_dat_root__32 ,or use use verbose mode and check the debug file
  

　　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
