# group server # # ## Check a file's timestamp. In this example, we test if a file is older ## than 15 minutes and assume something is wrong if its not updated. Also, ## if the file size exceed a given limit, execute a script # # check file database with path /data/mydatabase.db # if failed permission 700 then alert # if failed uid data then alert # if failed gid data then alert # if timestamp > 15 minutes then alert # if size > 100 MB then exec "/my/cleanup/script" as uid dba and gid dba # # ## Check directory permission, uid and gid. An event is triggered if the ## directory does not belong to the user with uid 0 and gid 0. In addition, ## the permissions have to match the octal description of 755 (see chmod(1)). # # check directory bin with path /bin # if failed permission 755 then unmonitor # if failed uid 0 then unmonitor # if failed gid 0 then unmonitor # # ## Check a remote host availability by issuing a ping test and check the ## content of a response from a web server. Up to three pings are sent and ## connection to a port and an application level network check is performed. # # check host myserver with address 192.168.1.1 # if failed ping then alert # if failed port 3306 protocol mysql with timeout 15 seconds then alert # if failed port 80 protocol http # and request /some/path with content = "a string" # then alert # # ## Check a network link status (up/down), link capacity changes, saturation ## and bandwidth usage. # # check network public with interface eth0 # if failed link then alert # if changed link then alert # if saturation > 90% then alert # if download > 10 MB/s then alert # if total upload > 1 GB in last hour then alert # # ## Check custom program status output. # # check program myscript with path /usr/local/bin/myscript.sh # if status != 0 then alert # # ############################################################################### ## Includes ############################################################################### ## ## It is possible to include additional configuration parts from other files or ## directories. # # include /etc/monit.d/* # # 导入其他单项服务的监控配置 # Include all files from /etc/monit.d/ include /etc/monit.d/*

· 通知周期设置

　
Monit默认情况下如果一个服务失败只发送一个通知： 　　alert foo@bar
　
如果您希望在服务保持处于失败状态时每十个周期通知一次，您可以使用： 　　alert foo@bar with reminder on 10 cycles
　
同样，如果您想在每个失败的周期获得通知，您可以使用： 　　alert foo@bar with reminder on 1 cycle

要禁止某些用户和服务的警报，可以在服务检查的局部配置里添加语句： 　　noalert mail-address

· 服务检测周期设置

可以使用every语句修改服务检查计划。 1.轮询周期倍数 EVERY [number] CYCLES 2.Cron-style EVERY [cron] # [cron] # * * * * * # 分 时 日 月 周 3.与Cron-style相反（do-not-check） NOT EVERY [cron] 示例： 示例1：每两个周期检查一次 check process nginx with pidfile /var/run/nginx.pid every 2 cycles 示例2：在上午8点到下午7点之间检查每个工作日 check program checkOracleDatabase with path /var/monit/programs/checkoracle.pl every "* 8-19 * * 1-5" 示例3：在星期日0AM到3AM之间不要在备份窗口中运行检查，否则运行具有常规轮询周期频率的检查。 check process mysqld with pidfile /var/run/mysqld.pid not every "* 0-3 * * 0" 注意不要使用特定的分钟，因为Monit可能不会在那分钟运行。
