My gists about Observability

Observability enthusiast and Grafana Champion, always looking for ways to improve software with better observability and what new insights can be gained. Delivering reliable software is always my priority. Combining existing tools often results in new ways to get an even better view. I work for OpenValue as a software & observability engineer and SRE.

    • Your local development of a Grafana plugin or dashboard may lack representative data. Connecting to production data sources may be impossible, but there are other ways to connect. Read more to find out how to use Grafana as a proxy to access the data.

    • The power of observability becomes visible when you combine signals and put it all together. Checks performed by Checkly can provide a piece of the puzzle that gives you a better view of what is happening. It would be really nice if you could combine the data from Checkly in the same Grafana dashboards as your other observability data. This post describes how to bring it together and how to add Grafana annotations to your dashboard based on Checkly results.

    • Updates from Checkly Based on my previous post I have been in contact with Checkly about two parts that were not working as expected. I have some updates on these topics today. Sending traces from Checkly to Tempo In the previous post I mentioned that the traces in my Grafana environment showed root span not yet received. The root span was not available. This requires Checkly to send these spans to my environment as well.

    • Checkly This week I came across Checkly, a code-first synthetic monitoring solution that can do API checks and browser checks using PlayWright. It would have saved me a lot of time if this had been around 8 years ago. At that time I was working on a project where we were doing some external checks with a vendor like Checkly, but it was all manual configuration in a web interface. And internally we had a checker tool running that did all sorts of internal checks, both HTTP checks and database checks.

    • An announcement was made at GrafanaCON. Alloy is introduced in the family of Grafana tools. Alloy is an open source distribution of the OpenTelemetry Collector, but is will also replace Promtail. In the Observability Toolkit I use both Promtail and OpenTelemetry Collector, so it makes sense to merge them. In this blog post I will replace Promtail with Alloy. In another post I will see how replacing of OpenTelemetry Collector with Alloy will look like.

    • Grafana Scenes can enhance your experience with Grafana dashboards by bringing observability data together and guiding users to the right data. Combining metrics, traces and logs helps to understand the actual behavior of a system. That is the goal of observability. If a dashboard or an app created with scenes does not give the right insights, then still the explore feature of Grafana is available to dive into all data available searching for the unknown-unknown.

    • Deep understanding of the actual behavior of a system is key for me. I like to know all the details because it helps me to see the whole picture. I am visually oriented, so tools like Grafana really help me in these situations. Observability is a topic that has come up in the last few years, but I have actually been doing this for years. But the good thing is that it is more standardized now.

    • One of the great things about OpenTelemetry is the standardisation of span attributes and resource attributes. An example of this is deployment.environment. Attribute Type Description Examples Requirement Level deployment.environment string Name of the deployment environment (aka deployment tier). staging; production Recommended Source: https://opentelemetry.io/docs/specs/semconv/resource/deployment-environment/ With Grafana Faro you can configure the environment, as I explained in my blog post about the setup of Grafana Faro. This adds environment to the setup. In my technical deep dive blog post I explained that the data is sent as logs and as traces.

    • With Grafana Scenes it is possible to create more than just dashboards. There are options to create dashboards that guide the user. Deep dives with drill down pages can help to analyse problems. And with a feature like time range comparison it is even possible to use a feature that is not available with normal dashboards. But how do you start developing with Grafana Scenes? One trend is to develop remotely, rather than on your local machine.

    • 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. This is how that setup looks like: But what kind of data is available now? Data sent by the browser The libraries from the Web SDK collect technical details about the browser interaction. The goal is not to track users, but to collect all sorts of technical data to see if there are problems with the web pages and what the perceived performance is for the users.
