I am using AWS Opsworks and AWS uses an old version of monit (5.3.2) to monitor their agent. Obviously, when their opsworks-agent dies, monit restarts it. Recently, I wanted to monitor few processes of my own and required newer versions of monit to use the explicit "restart" command support. I upgraded monit to 5.13. Now, monit does not restart opsworks agent if it dies!
I tried looking for changelog of monit to see if something was changed between versions, but could not find them for all versions beyond 5.7. Can someone please take a look at opsworks config below and see what might be breaking? opsworks-config follows - check process opsworks-agent with pidfile "/var/lib/aws/opsworks/pid/opsworks-agent.pid" start program = "/etc/init.d/opsworks-agent start" stop program = "/etc/init.d/opsworks-agent stop" depends on opsworks-agent-master-running depends on opsworks-agent-statistic-daemons-log depends on opsworks-agent-process-command-daemons-log depends on opsworks-agent-keep-alive-daemons-log group opsworks check process opsworks-agent-master-running matching "opsworks-agent:\smaster" if not exist for 2 cycles then restart group opsworks # check run of statistic daemon check file opsworks-agent-statistic-daemons-log with path "/var/log/aws/opsworks/opsworks-agent.statistics.log" if timestamp > 2 minutes for 3 cycles then restart if does not exist for 3 cycles then restart group opsworks # check run of process command daemon check file opsworks-agent-process-command-daemons-log with path "/var/log/aws/opsworks/opsworks-agent.process_command.log" if timestamp > 2 minutes for 3 cycles then restart if does not exist for 3 cycles then restart group opsworks # check run of keep alive deamon check file opsworks-agent-keep-alive-daemons-log with path "/var/log/aws/opsworks/opsworks-agent.keep_alive.log" if timestamp > 2 minutes for 3 cycles then restart if does not exist for 3 cycles then restart group opsworks - end of file Monit logs say restart done, but opsworks doesn't run. If I downgrade to 5.3.2, it does magically run!
