如果响应时间超过2秒，我想用monit来重新加载pm2 node.js站点。
这是我的监控configuration/etc/monit/monitrc ：
check process pm2 with pidfile "/root/.pm2/pids/siteName9000.pid" start program = "/usr/local/bin/pm2 start ~/pathToNodeApp/9000/app.js --name siteName9000" stop program = "/usr/local/bin/pm2 stop siteName9000" if failed port 9000 protocol HTTP request / with timeout 2 seconds then restart
然后在控制台中运行：
# monit restart pm2
然后在控制台中运行：
# monit -d 10 -c /etc/monit/monitrc
每10秒进行一次这个检查。
然后在监视/var/log/monit.log我看到：
[MSK May 18 06:57:05] info : 'pm2' restart on user request [MSK May 18 06:57:05] info : monit daemon with PID 22480 awakened [MSK May 18 06:57:05] info : Awakened by User defined signal 1 [MSK May 18 06:57:05] info : 'pm2' trying to restart [MSK May 18 06:57:05] info : 'pm2' start: /usr/local/bin/pm2 [MSK May 18 06:57:36] error : 'pm2' failed to start [MSK May 18 06:57:36] info : 'pm2' restart action done [MSK May 18 06:58:27] info : Awakened by User defined signal 1 [MSK May 18 06:58:27] error : 'pm2' process is not running [MSK May 18 06:58:27] info : 'pm2' trying to restart [MSK May 18 06:58:27] info : 'pm2' start: /usr/local/bin/pm2 [MSK May 18 06:58:27] info : monit daemon with PID 22480 awakened [MSK May 18 06:58:58] error : 'pm2' failed to start [MSK May 18 07:00:58] error : 'pm2' process is not running [MSK May 18 07:00:58] info : 'pm2' trying to restart [MSK May 18 07:00:58] info : 'pm2' start: /usr/local/bin/pm2
所以我的监控configuration不工作。
