Hi Doug, The times for agent runs typically do not correspond to any Puppet related tuning. The places that the agent comes into contact with the master during a puppet run, once they have received the catalog is file serving, filebucketing changed files and sending a report. Metrics to look for are how long does it take your puppet master to compile a catalog and are any of your agents timing out when requesting catalogs. Try checking out last_run_summary.yaml for figuring out which resources take the most time during the agent run. Typically I see poorly configured name servers and requests outside of the network as ways in which the agent will take longer to run. This thread might also help. https://ask.puppet.com/question/3/where-can-i-find-information-about-sizing-for-puppet-servers/ Best regards, -g -- Garrett Honeycutt @learnpuppet Puppet Training with LearnPuppet.com Mobile: +1.206.414.8658 -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
