Logging is a feature that virtually every application must have. No matter what technology you choose to build on, you need to monitor the health and operation of your applications. This gets more and more difficult as applications scale and you need to look across different files, folders, and even servers to locate the information you need. While you can use built-in features to write Python logs from the application itself, you should centralize these logs in a tool like the ELK stack.

Today Sysdig announced the availability of IBM Cloud’s new IBM Cloud service monitoring solution. The new capability – an extension of IBM Cloud Monitoring with Sysdig – provides pre-defined service metrics and dashboards for IBM public cloud services.

Greetings! This is Eldin and Ronald reporting in from the Solutions Engineering team at Grafana Labs. You’ve probably seen some previous posts from our colleagues Christine and Aengus or maybe some of the fantastic Loki videos that Ward has put up on YouTube. This week, Ronald and I will walk through how to leverage Prometheus and Loki as data sources to create a simple but awesome Grafana dashboard that enables quick searches of logs.

DHH just coined the term “Citadel,” which finally gives us an excellent way to reference how we approach tech at AppSignal. We said, “Hey, this is us! Our thing has a name now”. In addition to the Majestic Monolith, someone should write up the pattern of The Citadel: A single Majestic Monolith captures the majority mass of the app, with a few auxiliary outpost apps for highly specialized and divergent needs.

Elixir describes itself as "a dynamic, functional programming language designed for building scalable and maintainable applications." Although it's a relative newcomer, Elixir is built on top of the functional programming language Erlang. Elixir is capable of using any Erlang library, and is ideal for use cases such as web development and distributed and low-latency systems. The power, dynamism, and feature-rich toolset of Elixir have made it somewhat of a "cult classic" among programmers.

TLS (and the previously used SSL) protocols make the web go round. They are fundamental when establishing a link between two computers, creating a very special mathematical relationship signified by the all-encompassing gesture of friendship: the handshake. So fundamental, in fact, that we probably take them for granted when we shouldn’t. The user relies on TLS encryption every day to protect data and the integrity of a session.
