Benchmark puppetDB

[shell heriyanto]

Dear All,

I know puppetDB its more faster than storeconfigs, but to replace storeconfigs with puppetDB into production server

Its need more explanation than some link from puppetlabs, need prove to my bos and team.

For testing i just have 1 puppetmaster and 1 and 2 puppet agent, how i can look different performance?

Its that any idea / or complex puppet stanza to benchmark / compare this with storeconfigs?

Regards,

Thanks

A catalog compile should show the difference in speed (especially one
with large number of resources). This is discussed in the Puppet DB
blog post. Also Deepak has great talk at Puppet Conf discussing why
PuppetDB is async (which isn't something quite as easy to benchmark
with just 2 agents):

Hi Nan,

Thank for your reply, yes that what im talking about, i can't prove just with link to puppet blog,

yes you right catalog compile should give our output, do you have some example of one

with large number of resources for my testing?

Thank for your help

Regards,

Hello Heriyanto,

Were you able to come up with something to solve your problem?  We don't currently have any sort of sample catalog that could be used to easily benchmark the performance difference in your environment, though your e-mail has prompted some internal discussion about how we could conceivably provide something like that in the future.

I suspect that if you simply time any agent run in your environment (for an agent with a non-trivial number of resources) against legacy storedconfigs, and then time it again with PuppetDB, you should notice some difference (because legacy storeconfigs must synchronously insert all of the catalog data into the database before the run completes).  You could also run your master with the "--debug" flag, which might provide you with some timing info for the various phases of the process.

However, the biggest benefits come when you have a master that is under some load from concurrent agent requests.  That might be a bit more tricky to simulate in your own environment if the blog posts and other data we've posted isn't sufficient, but we would be happy to try to help if you have questions!

Thanks

Chris

Hello Chris,

Thanks for your reply, i already solved this by use my production modules. But yes, its take some time to build half my of production enviroment. Thank for yours great work.
