In my previous #OneIdentity Active Roles blog, you learned how to forward #Active #Roles logs to a central #syslog_ng server to parse and store the logs. In this blog, I’ll show you how to:

- Work with parsed Active Roles logs.
- Store #logs to various document stores.
- Prepare long-term storage.
- Send #alerts for some critical events.

Even if this blog about commercial software, the name-value pairs concept is the same in the #opensource syslog-ng.

Mastering #LogManagement in #Kubernetes is pivotal for achieving enhanced observability and maintaining system reliability in a microservices architecture. Kubernetes, with its distributed nature, high log volumes, and dynamic environment, presents unique challenges. However, with the right strategies, these challenges can be transformed into opportunities to gain deeper insights.

In this #InfoQ article, Prithvish Kovelamudi dives into the challenges, strategies & best practices for seamless log management in your Kubernetes environment.

Three weeks from now I'll be in Nürnberg for the @opensuse conference. I'll give a talk about why central #logging is important:

events.opensuse.org/conference

Most of my talk will apply to any #LogManagement sw, but of course my config examples will come from syslog-ng 😉

openSUSE EventsWhy to log centrally?Why is central logging so important? Convenience, availability and security. Convenience, as you have a single place to check instead of many. Availability, as you can check log messages, even if the sending host is unavailable. Security, as logs leave hosts as soon as they are produced, so an attacker has no chance to modify them. Developers, operators, and security have a single view of the whole network and can easily correlate events from multiple hosts. Often, the various tools to analyze log messages provide you with their own agents to forward logs to SIEM or other analytics tools. However, this is inefficient for several reasons. Most importantly, it is a waste of computing resources. You install multiple applications to do the same job: forwarding log messages. And these messages then travel through your network multiple times. So, what you should do instead is build a dedicated log management layer for central log collection. This ensures that log messages are collected only once. Using the OpenTelemetry protocol, logs, traces and metrics can be collected together, simplifying the architecture of collecting data about your infrastructure even further. From this talk, you can learn how to implement central logging using syslog-ng and how OpenTelemetry changes logging. Syslog-ng in openSUSE Tumbleweed already supports the OpenTelemetry protocol.
