After the very successful first issue on Foreman and Graylog, the next one is on Puppet.
First speakers are announced including myself giving the talk “Let the Foreman pull your puppet’s strings”. Others are perhaps also well known in the community like Martin Alfke from example42, Tim (bastelfreak) Meusel who is part of Vox Pupuli and Kris Buytaert and some of his colleagues from inuits.
If you are interested, have a look at https://opensourcecamp.de.
If monitoring is also one topic you are interested, the Open Source Camp takes place right after the Open Source Monitoring Conference at the same venue.
I will update here when more details are published.
