logz.io Releases Feature to Automatically Identify Patterns within Log Data
logz.io released a new feature to help identify recurring patterns within log data. This new feature, entitled Log Patterns, automatically analyzes millions of log messages in real-time to reduce the volume of logs and potentially reveal common trends. This feature is their third feature to provide automated interpretation and filtering of log messages under the label of AIOps.

Testing Complex Distributed Systems at FT.com: Sarah Wells Shares Lessons Learned
The complexity in complex distributed systems isn’t in the code, it’s between the services or functions. Testing implies balancing finding problems versus delivering value, said Sarah Wells at the European Testing Conference. Testers often have the best understanding of what the system does; they have a good hypothesis about what went wrong, and are able to validate it pretty quickly.

Building Observable Distributed Systems
Today's systems are more and more complex; microservices distributed over the network and scaling dynamically, resulting in many more ways of failure, ways we can't always predict. Investing in observability gives us the ability to ask questions to systems, things we never thought about before. Some of the tools that can be used for this are metrics, tracing, structured and correlated logging.

Microsoft Adds Application Insights Support for Azure Functions
Microsoft recently announced an initial preview of Application Insights support for Azure Functions. As a result of this integration between the two services, developers now get built-in instrumentation for their code and a portal to view trends in their code’s performance. Developers are also able to set monitoring thresholds which can be used to create alerts or a callout to external webhooks.

Five Ways to Not Mess Up Microservices in Production
Alex Zhitnitsky of Takipi has written about five ways to try to improve the chances of successful deployed of microservices into production. As we will see, they share many similarities with other independent efforts, perhaps leading us to agreement on top areas of concern, if not ways of solving these problems.

Log4j 2.6 Goes Garbage-Free
Log4j, the popular logging library for Java, will include a number of configuration options that allows it to run in a completely garbage-free manner. The release follows previous attempts to improve the performance of logging libraries, and has been positively received by the industry. Further changes to increase the number of scenarios in which log4j can run garbage-free are expected.
