Almost 15 years ago, Balabit had a campaign, stating that #syslog_ng could process 650k messages a second. Now I am happy to present 7 #million #EPS (events per second). Timing the announcement to April 1 is not a coincidence :-) #AprilFoolsDay

Nobody responded to my related posts for years, so 4.11 will be the last release to have it

Terrace party anyone? 😉 First day in the office this year, and I got this wonderful view when arrived.

I am back after a long #vacation. If you need an urgent response from me about #syslog_ng or anything, send it now (again). Or we can discuss it #IRL on our terrace 🥶

My last working day this year. I wish you a Merry Christmas and a happy new year using my all time favorite greeting card :-)
I'll be back with #syslog_ng news and blogs next year.
