Hi All, An update on this thread..
Based upon some real world testing, I've updated the Passenger wiki to give some performance and with memory consumption (one of the main reasons for switching to Passenger right?): http://reductivelabs.com/trac/puppet/wiki/UsingPassenger Let me know if you have any comments, suggestions. ------ Suggested Tweaks Based upon my (Larry Ludwig) testing of passenger/puppetmasterd I recommend adjusting these options in your apache configuration. PassengerPoolIdleTime - Set to 5 min or less. The shorting this option allows for puppetmasterd to get refreshed at some interval. This option is also somewhat dependent upon the amount of puppetd nodes connecting and at what interval. PassengerMaxPoolSize - to 15% more instances than what's needed. This will allow idle puppetmasterd to get recycled. The net effect is less memory will be used, not more. PassengerUseGlobalQueue on - Since communication with the puppetmaster from puppetd is a long process (more than 20 seconds in most cases) and will allow for processes to get recycled better PassengerHighPerformance on - The features Passenger offers with this feature disabled are not needed with Puppet. No different than with traditional web servers, once your service starts using swap performance degradation will occur. So be mindful of your memory/swap usage on your Puppetmaster. To monitor the age of your puppetmasterd processes within Passenger, run passenger-status the output you should be concerned with is: ... ----------- Domains ----------- /etc/puppet/puppetmasterd: PID: 7355 Sessions: 0 Processed: 5747 Uptime: 1h 3m 30s PID: 9950 Sessions: 0 Processed: 2941 Uptime: 27m 27s PID: 7117 Sessions: 0 Processed: 7208 Uptime: 1h 8m 33s PID: 7575 Sessions: 0 Processed: 6307 Uptime: 57m 19s PID: 9653 Sessions: 0 Processed: 2525 Uptime: 37m 31s My personal preference is I like Passenger recycling puppetmasterd every few hours to ensure memory/garbage collection from Ruby is not a factor. -L -- Larry Ludwig Reductive Labs --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
