My gists about Observability

On day 3 of the hackathon, I compared Opus 4.8 and Sonnet 4.6 using the gcx tool and debug-with-grafana skill to diagnose a fault-injected failure in the OpenTelemetry demo.

Day 2 of the hackathon.

Day 1 of the OpenValue hackathon in Belgium.

Incident reports are often static and lack the detail needed for deep analysis.

An Application Observability Code Challenge with virtual threads.

The third and final day of the hackathon.

The second day of the hackathon was a mix of activities.

Together with my colleagues of OpenValue Utrecht we are having a hackathon at a nice place in the south of Belgium.

The first of the Application Observability Code Challenges step by step revealed.

The first of the Application Observability Code Challenges is now available.

Application Observability Code Challenges are a way to challenge yourself to improve the observability of a sample application.

Your local development of a Grafana plugin or dashboard may lack representative data.

The power of observability becomes visible when you combine signals and put it all together.

Updates from Checkly Based on my previous post I have been in contact with Checkly about two parts that were not working as expected.

Checkly This week I came across Checkly, a code-first synthetic monitoring solution that can do API checks and browser checks using PlayWright.

An announcement was made at GrafanaCON.

Grafana Scenes can enhance your experience with Grafana dashboards by bringing observability data together and guiding users to the right data.

Deep understanding of the actual behavior of a system is key for me.

One of the great things about OpenTelemetry is the standardisation of span attributes and resource attributes.

With Grafana Scenes it is possible to create more than just dashboards.

As shown in my previous post you can add Grafana Faro to get more information about users who visit a website, in my case my own blog.

If you use Hugo to create a blog or website, as I do, and you use GitHub Pages to host the blog, it’s hard to get observability signals in your usual observability stack.

I am passionate about Observability already for a long time.
