All About Structured Metadata in Loki (Loki Community Call August 2025)

Tue, 12 Aug 2025 19:56:32 -0700

In this video, Jay Clifford and I talk to Senior Software Engineer Salva Corts Sánchez from the Loki team about structured metadata in Loki. We discuss what it is, why you might want to use it, and also how to query it. Structured metadata is especially useful if you’re instrumenting your system with OpenTelemetry, so we also touch on that.

The Road to Loki 4.0 (Loki Community Call June 2025)

Tue, 24 Jun 2025 13:56:45 +0200

In this video, my colleague Jay Clifford and I interview Ed Welch, Principal Engineer on the Loki team at Grafana Labs, about the upcoming Loki 4.0 release. We talk about some pretty big features that make this next release almost an entire rewrite of Loki, including:

A shift towards columnar storage, using a new storage format called “DataObject”
A new Kafka/WarpStream architecture that decouples the read and write paths
A new Loki Query Engine that decouples the query language from the rest of the system, allowing for more options in, for example, allowing for SQL queries against Loki in the future

Meta-monitoring Loki (Loki Community Call May 2025)

Mon, 12 May 2025 17:59:48 +0100

In this Loki Community Call, we talk about the need for meta-monitoring Loki: why Loki needs to be monitored, what to watch out for, and how to do it. We talk about different ways to get information from Loki that allow you to make it reliable, consistent, and performant, including a Helm chart to deploy a meta-monitoring stack on Kubernetes. We discuss the Loki mixin for Grafana and how to use it to visualize data about Loki. On the call are Jay Clifford, Nicole van der Hoeven, and Dylan Guedes from Grafana Labs.

All about OTel and Logging on Kubernetes with Loki (Loki Community Call April 2025)

Fri, 25 Apr 2025 17:57:58 +0100

In this pre-recorded Loki Community Call, we talk all about OTel and logging on Kubernetes with Cyril Tovena, Ward Bekker, Jay Clifford, and Nicole van der Hoeven at KubeCon EU 2025 in London. We discuss when why you should switch to OTel and why you shouldn’t, what OTLP is exactly, and best practices for ingesting data through an OTLP endpoint.

Do's and Don'ts of Scaling Loki Cache (Loki Community Call March 2025)

Tue, 25 Mar 2025 17:56:00 +0100

In this Loki community call, Poyzan (Staff Engineer on the Loki team) returns this time with Paul Rogers (Staff Engineer on the Loki team) to talk all about Loki cache! This topic was heavily discussed in our “How to run Loki at scale on Kubernetes” call. Some of the topics we will cover:

Types of cache and cache tiering
Best practices for scaling your cache
Understanding failure scenarios with Loki cache and how to detect them

Best Practices for Recording and Alerting (Loki Community Call February 2025)

Wed, 26 Feb 2025 17:54:15 +0100

In this Loki Community Call, we talk about the best practices for recording and alerting rules with Loki Staff Engineer George Robinson and Senior Developer Advocates Jay Clifford and Nicole van der Hoeven. Ever wondered what’s the difference between the Ruler and Alertmanager? 🤔 Curious about the different modes the Ruler can run in when querying Loki? Want to avoid the most common pitfalls when setting up alerting and recording rules? We cover all of these, including optimizing rule performance to structure alerts effectively.

How to Run Loki at Scale on Kubernetes (Loki Community Call January 2025)

Thu, 23 Jan 2025 17:51:00 +0100

Happy New Year from the Loki Engineering team. To kick off 2025, Nicole and Jay will be joined by Poyzan Taneli from the Loki Engineering team to discuss how to run Loki at scale on Kubernetes. If you are currently running Loki in microservices mode or preparing to do so, we will be discussing best practices for scaling its components to meet the demands of production use cases.

How many Ingesters vs Queriers do I need?
What is the minimum cost of running Loki as a production cluster?
What is the average node size for running Loki? How do I monitor my Loki deployment?

Grafana Loki Query Best Practices with LogQL (Loki Community Call December 2024)

Thu, 05 Dec 2024 17:48:49 +0100

In this December’s Loki Community Call, Cyril Tovena, Senior Principal Engineer and LogQL guru walks us through a Grafana Loki query tutorial with LogQL, the Log Query Language used for Loki. He talks about the key “Dos and Don’ts” of LogQL, offering practical tips to help you write better queries, boost performance, and sidestep common mistakes.

Whether you’re tuning up your current setup or just diving into LogQL, Cyril’s got you covered. Bring your questions, connect with the Loki community, and pick up insights that’ll make your log-querying life easier. See you there!

Make sure you leave your questions here.

Cyril is joined by Senior Developer Advocates Jay Clifford and Nicole van der Hoeven.

All About Logs Drilldown (Loki Community Call October 2024)

Thu, 03 Oct 2024 17:45:33 +0100

In this Community Call, Senior Software Engineer Trevor Whitney talks to us all about Drilldown Logs for Grafana Loki, an open-source app for visualizing logs from Loki in Grafana without needing to learn and write LogQL queries. He is joined by Senior Developer Advocates Nicole van der Hoeven and Jay Clifford.

Bloom Filter Changes for Grafana Loki (Loki Community Call September 2024)

Thu, 05 Sep 2024 17:41:18 +0100

In this Community Call, Senior Software Engineer Christian Haudum talks to us about bloom filter changes for Grafana Loki, including the deprecation of the bloom compactor and a pivot towards creating bloom filters for structured metadata. Bloom filters are a probabilistic data structure that we’re using to improve query performance in Loki.

Community Calls are monthly meetings that are open to everyone interested in the development of Loki. They are an opportunity for software engineers working on Loki to discuss new features as well as for open-source users of Loki to ask questions.
