linux – 当受监视的进程失败时,如何让monit执行多个操作？

我有一个我想用monit监控的自定义服务.当进程失败时,我想将日志复制到共享文件系统并重新启动该服务.像下面这样的东西,但我不确定是什么.任何提示将不胜感激.

check process pipeline with pidfile /var/run/pipeline.pid
   start program = "/sbin/start pipeline"
   stop  program = "/sbin/stop pipeline"
   if 10 restarts within 10 cycles then timeout
   # Not sure what to write next
   if <service has Failed> 
      restart and 
      exec "/bin/bash -c 'cp /var/log/upstart/pipeline.log /nfs/logs/`hostname`.`date +'%m-%d-%Y_%H.%M.%s'`.log'"

解决方法

我会写一个包含所需事件动作的小bash脚本.从Monit调用该脚本.

它更清洁,更模块化,行为更可预测.同样的想法适用于cron工作.

例如,从Monit examples page开始,您是否愿意支持这一点：

check directory httpd_core with path /var/crash/core if changed
timestamp then exec “/bin/bash -c ‘if [ /bin/cat
/tmp/monit_httpd_core.tmp | head -1 != /bin/ls
/var/crash/core/core.httpd* | tail -1 ]; then /usr/bin/gdb -x
/etc/gdb.batch /usr/sbin/httpd /bin/ls /var/crash/core/core.httpd* |
tail -1 | tee /tmp/monit_httpd_core.tmp | mail -s httpd_crash
[e-mail] [e-mail]; fi'”

或这个：

check directory httpd_core with path /var/crash/core   if changed
timestamp then exec script.sh

其中script.sh包含所有的丑陋.
