On Dec. 18, 2023, we unintentionally introduced some new features and two minor breaking changes in the Grafana 10.2.3 patch release. These changes were originally intended for Grafana 10.3, which we plan to release later this month, but these commits were merged into the 10.2.3 release branch early due to a mistake in our release process. Because Grafana 10.2.3 introduces more changes than expected in a typical patch release, there’s a risk of more bugs than expected.

For this week’s installment of “The concise guide to Loki,” I’d like to focus on an interesting topic in Grafana Loki’s history: ingesting out-of-order logs. Those who’ve been with the project a while may remember a time when Loki would reject any logs that were older than a log line it had already received. It was certainly a nice simplification to Loki’s internals, but it was also a big inconvenience for a lot of real world use cases.

When monitoring sensor data, such as data from a weather station, a home security system, or a home automation assistant, it’s useful to have an alerting system in place, as well. By setting up alerts for sensor data, you can automatically receive notifications when any significant event occurs — whether that’s someone arriving at your front door or a thunderstorm rolling in.

Grafana Alerting helps you identify issues almost immediately after they occur — and you don’t have to constantly check your system to get the insights you need. Instead, Grafana Alerting sends alert notifications to reach you wherever you are, whether that’s in a Slack channel or in a messaging app like Telegram. Telegram is a viable option for receiving alerts, especially when you want personal or individual notifications rather than those sent to a team.

Thanks for joining me for Part 3 of “The concise guide to Grafana Loki,” a series of blog posts that takes a closer look at best practices for various aspects of using the log aggregation system. Today’s post is my holiday present for all the folks out there running Loki who would like to get the most query performance they can out of their cluster.

As the number of Grafana users grows each year, so does the variety of reasons people are using Grafana dashboards. During 2023, members of the our community — both inside and outside of the company — shared some of their incredible professional and personal projects, including how Grafana has allowed them to successfully launch a rocket, cut back on carbon emissions, and even help balance a national power grid.
