#logmanagement — Public Fediverse posts

Good news for those reading my #syslog_ng #openssl 4.0 blog at the original publication date: version 4.12 of syslog-ng is now available, and openssl 4.0 is supported without backporting patches:

When the CI/CD pipeline fails, everyone stops shipping and starts guessing.

Environment mismatches, expired credentials, flaky tests, infrastructure issues. The first error message is rarely the real root cause.

The fix isn't faster debugging. It's a repeatable investigation process: centralize logs from every pipeline stage, confirm scope, identify the failed step, isolate what changed.

We are removing #HDFS support from #syslog_ng, the last driver written in #Java. As a #scream test, I started to disable Java support in syslog-ng on @opensuse and @fedora. Let us know, if you use the Java destination with your own code!

Storing every log forever? That's not security — that's a storage bill.

Effective log retention means tiering your data: hot for active monitoring, warm for periodic audits, cold for long-term compliance.

The right strategy keeps the signal, cuts the noise, and scales without breaking your budget.

Although #OpenSSL 4.0 released just two weeks ago, the syslog-ng project has already received a #GitHub issue complaining that we do not support it. So, before we would allocate too much effort on it: what should we expect?

NIS2 is now in effect across the EU — and non-compliance carries fines up to €10M or 2% of global turnover.

Covered entities in energy, health, finance, transport, and more need to meet tight incident notification windows: 24 hours for early warning, 72 hours for a full notification, 30 days for the final report.

Centralized log management is the foundation that makes those timelines achievable. We've written up a practical guide covering access monitoring, network monitoring, data exfiltration detection, and post-incident reporting.

Modern IT environments produce massive volumes of log data.

Log correlation connects those events across systems to detect threats sooner, reduce alert fatigue, and speed root-cause analysis.

Learn how it works and best practices for implementing it.

Version 4.11 of #syslog_ng will feature a brand-new #Kafka source. While it is being tested and reviewed, we are working on reducing the number of open issues. What should be #fixed next in syslog-ng?

#LogManagement

⚡ 10x faster log processing
⏱️ Latency reduced from 30 seconds to under 3 seconds
📈 99.95% availability sustained during peak global events

Kaizen Gaming modernized log management across more than 600 microservices supporting the Betano platform. SRE and Platform Engineering teams gained real-time visibility, faster incident response, and predictable performance during major sporting events.

Led by Marinos Giamouridis and Miltiadis Tsatsakis, the Kaizen team combined high-throughput ingestion, Illuminate content, and Data Lake storage with Graylog Enterprise to reduce noise, improve signal quality, and control operational costs. The result is an observability platform built for scale, speed, and reliability across hybrid environments.

Is there anyone still using #HDFS? Not just with #syslog_ng, but at all. I'm curious, as the HDFS destination is the last #Java-based driver in syslog-ng.

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

The next #syslog_ng release will feature a brand new @ApacheKafka source. You can already test this if you do not mind building the syslog-ng package yourself. Luckily it's easy and does not require developer knowledge:
