Further, depencies are producing some backwards behavior. In the following example starting redis server is triggering the start of my resque worker, even though the dependency tree is the reverse. IMO, starting redis-server should trigger nothing after it starts since it's resque_worker_1 that depends on redis-server.
Here's my conf, followed by a status and tailing monit.log. Starting with all servies turned off. # cat /etc/monit/monit.conf set httpd port 2812 and use the address localhost allow 127.0.0.1 check process redis-server with pidfile /var/run/redis.pid start program = "/etc/init.d/redis-server start" with timeout 30 seconds stop program = "/etc/init.d/redis-server stop" check process resque_worker_1 with pidfile /u/apps/stocks/shared/pids/resque_worker_1.pid start program = "/bin/sh -c 'cd /u/apps/stocks/current ; bundle exec rake environment resque:work RAILS_ENV=production QUEUE=daily_memoizer,high,medium VERBOSE=1 PIDFILE=/u/apps/stocks/shared/pids/resque_worker_1.pid >> log/resque_worker_1.log 2>&1 &'" as uid blue and gid blue with timeout 45 seconds stop program = "/bin/sh -c 'cd /u/apps/stocks/shared/pids/ ; sudo kill -QUIT $(cat resque_worker_1.pid) || true'" as uid jsharpe as gid jsharpe with timeout 120 seconds if totalmem is greater than 200 MB for 5 cycles then restart depends on redis-server group resque # monit status The Monit daemon 5.3.2 uptime: 8m Process 'resque_worker_1' status Not monitored monitoring status Not monitored data collected Mon, 15 Jul 2013 22:43:20 Process 'redis-server' status Not monitored monitoring status Not monitored data collected Mon, 15 Jul 2013 22:43:20 System 'system_stocks-app' status Not monitored monitoring status Not monitored data collected Mon, 15 Jul 2013 22:43:20 # monit start redis-server /var/log/monit.log [EDT Jul 15 22:45:26] info : 'redis-server' start on user request [EDT Jul 15 22:45:26] info : monit daemon at 2898 awakened [EDT Jul 15 22:45:26] info : Awakened by User defined signal 1 [EDT Jul 15 22:45:26] info : 'redis-server' start: /etc/init.d/redis-server [EDT Jul 15 22:45:26] error : monit: Error reading pid from file '/var/run/redis.pid' [EDT Jul 15 22:45:26] info : 'resque_worker_1' start: /bin/sh [EDT Jul 15 22:45:46] info : 'redis-server' start action done # monit status | egrep 'System|Process|status' Process 'resque_worker_1' status Running monitoring status Monitored Process 'redis-server' status Running monitoring status Monitored System 'system_stocks-app' status Not monitored monitoring status Not monitored
