Monit and BackgroundDB

Posted in Forums : Ask a Rails expert

Toby Hede Profile... about 1 month ago Authority 50 Posting Rating 32 Sign in to rate this post	I know that this is only vaguely a “Rails” question but it has me stumped. I am having trouble getting backgroundrb started through Monit. I end up with “Does not exist” as the Monit status. `1. check process backgroundrb 2. 3. with pidfile /var/www/apps/shared/pids/backgroundrb_12000.pid 4. 5. start program = "/usr/bin/ruby /var/www/apps/current/script/backgroundrb start -e production" 6. 7. stop program = "/usr/bin/ruby /var/www/apps/current/script/backgroundrb stop" 8. 9. if totalmem is greater than 80.0 MB for 4 cycles then restart 10. 11. if cpu is greater than 80% for 4 cycles then restart 12. 13. if 20 restarts within 20 cycles then timeout 14. 15. group app` I can start backgrounrb fine from the command line using: ”/usr/bin/ruby /var/www/apps/current/script/backgroundrb start -e production” Wondering why this may cause trouble when called by Monit. My mongrel_cluster config works fine and Monit is managing it.

Toby Hede Profile... about 1 month ago Authority 50 Posting Rating 32 Sign in to rate this post	Thanks for the response. I’ve checked the permissions and they are the same for the mongrel_cluster. My syslog looks like this: Mar 27 03:45:20 monit¹⁵⁴⁷⁷: ‘backgroundrb’ process is not running Mar 27 03:45:20 monit¹⁵⁴⁷⁷: ‘backgroundrb’ trying to restart Mar 27 03:45:20 monit¹⁵⁴⁷⁷: ‘backgroundrb’ start: /usr/bin/ruby Mar 27 03:48:20 monit¹⁵⁴⁷⁷: ‘backgroundrb’ process is not running Mar 27 03:48:20 monit¹⁵⁴⁷⁷: ‘backgroundrb’ trying to restart Mar 27 03:48:20 monit¹⁵⁴⁷⁷: ‘backgroundrb’ start: /usr/bin/ruby Don’t appear to be any errors. Just nothing …

Does the PID file get created? If you run the start command, exactly as it is in monit, from the command line, what happens?

Toby Hede Profile... about 1 month ago Authority 50 Posting Rating 32 Sign in to rate this post	Peter, thanks, that got it. It’s been working … there was just a backroundrb process that was open and stopping monit from managing it.
