Why "#syslog_ng can do 7 million EPS" was announced on #AprilFoolsDay? It is a completely valid result. However, it was measured not in a #production, but in a #laboratory environment.

So, it's an absolutely stunning result, just impossible in production.

My new toy: April 1 syslog-ng performance tests

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 :-) While the 650k EPS measurement was true, it was misleading. This value was measured right after syslog-ng 3.2 introduced multi-threading, in lab environment, under optimal circumstances, using synthetic log messages. However, there was no fine print explaining this, just the statement that syslog-ng could process 650k EPS.

I have an aging, but fully functional #MacBook, which I bought for #syslog_ng testing. @homebrew no more fully supports old, #Intel-based Macs. This blog helps to compile the latest syslog-ng release on these old, but otherwise functional machines.

I love wearing #logowear: promotional t-shirts and other items, for products and projects I like. #syslog_ng, #IBM, #OneIdentity, @turris, @opensuse and many more. Yesterday I was at a #Solaris concert (not the operating system, but the #progrock band), and chose to wear something not IT-related. Imagine my surprise: other than some #music t-shirts, I have seen tons of IT-related clothing at this fantastic #concert 🙂

I'm investigating a regression that appeared after upgrading #OpenJDK in a setup where #syslog_ng communicates with a #Riemann server (a Java application).

My investigation led me to a C library (riemann-c-client, used by syslog-ng) that uses #GnuTLS to establish a mutually authenticated TLS connection to the Java service. The library provides a CLI utility that allows me to reproduce the problem, which suggests that the issue lies in this library rather than in syslog-ng itself.

@opensuse I also updated the @fedora #Rawhide package, and according to the syslog-ng page on #repology, it's already there: https://repology.org/project/syslog-ng/versions

However, Rawhide still had #syslog_ng 4.10.2, when I checked a few minutes ago...
