Histograms are one of my favorite topics in the Prometheus universe. Last November, I delivered a talk at PromCon EU 2019 that was titled Prometheus Histograms – Past, Present, and Future. Only the part about the past had to be cut due to time constraints. But I made a promise to resurrect my talk about the history of histograms and I kept my word. In February, I premiered the Secret History of Prometheus Histograms at FOSDEM 2020.

Hello again! We are Eldin and Christine – or, as our lovely editor has dubbed us, Regis and Kelly – jumping back in for another post. This week, to highlight the big tent and community theme, we are going to write about how our Datadog plugin allows you to “see it all in one place.” Datadog is a popular monitoring and analytics platform that allows you to easily install an agent so you can get started with collecting metrics right away.

The COVID-19 pandemic has forced many companies to require employees to work from home. It’s a new normal for many, but at Grafana Labs our team has always recruited and operated with a remote-first culture in mind. To help everyone transition to a home office environment, we launched a new WFH series in which Grafana team members have been sharing their best advice for staying productive at home – yes, even if you have kids around.

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.

We’re happy to announce that Cortex v1.0 has been released! The horizontally scalable, durable, and fast Prometheus implementation is now generally available for production use. At Grafana Labs, we’ve been using Cortex in production for almost three years, including to power the Prometheus backend for the Grafana Cloud managed logging and metrics platform.

It has been a little over 2 months since 1.3.0 was released. We started prepping for the 1.4.0 release several weeks ago; however, when I was writing this very blog post for the release, we discovered some confusing stats from the new statistics objects (which we’ll talk about in a bit). After sorting that out, we played the usual game of, “Wait, don’t release yet!

As everyone knows, the Grafana project began with a goal to make the dashboarding experience better for everyone, and to make it easy to create beautiful and useful dashboards like this one. But as Andrej Ocenas, a full stack developer at Grafana Labs, said in a recent FOSDEM 2020 presentation, the company has bigger ambitions for Grafana than just being a beautiful dashboarding application. What Grafana Labs is really aiming to do now is make Grafana into a full observability platform.

Have you heard about using the hash ring in Loki and Cortex? Here is a short version: In Cortex and Loki, the ring is a space divided by tokens into smaller segments. Each segment belongs to a single “ingester” (component in Cortex and Loki that receives data) and is used to shard series/logs across multiple ingesters. In addition to the tokens, each ingester also has an entry with its ID, address, and the latest heartbeat timestamp updated periodically.
