Grafana Explore makes correlating metrics and logs easy. Prometheus queries are automatically transformed into Loki queries . And we will be extending this feature in Grafana 8.0 to support smooth logs correlation not only from Prometheus, but also from Graphite metrics. Prometheus and Loki have almost the same query syntax, so transforming between them is very natural. However, Graphite syntax for queries is different, and in order to map it to Loki, some extra setup is required.

For many years, it has been possible to scale Cortex clusters to hundreds of replicas. The relatively simple Dynamo-style replication relies on quorum consistency for reads and writes. But as such, more than a single replica failure can lead to an outage for all tenants. Shuffle sharding solves that issue by automatically picking a random “replica set” for each tenant, allowing you to isolate tenants and reduce the chance of an outage.

Whether it’s during an incident to find the root cause of the problem or during development to troubleshoot what your code is doing, at some point you’ll have an issue that requires you to search for the proverbial needle in your haystack of logs. Loki’s main use case is to search logs within your system. The best way to do this is to use LogQL’s line filters. However, most operators are case sensitive.

Daniel is a Site Reliability Engineer at He’s especially interested in observability, distributed systems, and open source. During his free time, he helps maintain Grafana Tempo, an easy-to-use, high-scale distributed tracing backend. Distributed tracing is a way to track the path of requests through the application. It’s especially useful when you’re working on a microservice architecture.

We built Grafana Enterprise Metrics (GEM) to empower centralized observability teams to provide a multi-tenanted, horizontally scalable Prometheus-as-a-Service experience for their end users. The GEM plugin for Grafana is a key piece of realizing this vision. It provides a point-and-click way for teams operating GEM to understand the state of their cluster and manage settings for each of the tenants within it.

I have been using Grafana for almost four years now, and in that time it has become my go-to tool for my application observability needs. Especially now that Grafana allows you to also view logs and traces, you can easily have all three pillars of observability surfaced through Grafana. As a result, when I started working on the Elixir PromEx library, having Grafana be the end target for the metrics dashboards made perfect sense.

Since we launched Grafana Enterprise Metrics (GEM), our self-hosted Prometheus service, last year, we’ve seen customers run it at great scale. We have clusters with more than 100 million metrics, and GEM’s new scalable compactor can handle an estimated 650 million active series. Still, we wanted to run performance tests that would more definitively show GEM’s horizontal scalability and allow us to get more accurate TCO estimates.

A trip to the DMV — and a realization that there had to be a better, more modern way for the system to work — sparked the idea for PayIt, a secure cloud service provider for digital government that launched in 2013. The company’s mission is to help state, local, and government agencies reach their constituents better and more effectively, shifting the reliance from in-office payments to digital ones.

The Grafana Agent team is happy to announce that Grafana Agent 0.14.0-rc2 includes improved Windows support. Up until now, running Grafana Agent — our tool for gathering metrics, logs, and traces — in Windows was difficult and not well supported for Windows best practices. In short, it was not a good Windows citizen. In the new release candidate, we’re making changes to improve the experience, based on feedback from GitHub issues, customer contacts, and our own experience.

When Grafana Labs CEO and co-founder Raj Dutt announced to the team that the company would be relicensing our core open source projects from Apache 2.0 to AGPLv3, he opened the floor for discussion and encouraged anyone who had further questions to reach out. We believe in honesty and transparency, so we collected hard questions from Grafanistas, and Raj answered them for this public Q&A. The time felt right. As I’ve said publicly before, I’ve been thinking about this topic for years.

Correlation between metrics, logs, and traces should be as effortless as possible. This helps you make better decisions and actions. The Grafana Labs open-source observability stack enables powerful correlations between your metrics, log, and traces. The key here is to have consistent metadata across the three pillars of observability. Let me demo you how this works in this video.

At Grafana Labs, we believe you should unify your data, not your database. We want to help you with your observability, not own it But what if you have multiple teams using multiple open source and commercial solutions? Not a problem. To give an example, here is a quick demo of Splunk, Elastic, and Loki logs combined into one UI in #Grafana This is more than a dashboard; it's a composite panel with transformations of all three sources Your teams should be able to use best-of-breed technologies rather than being locked into one

Loki doesn't index your logs, and that is a very different approach than popular full-text search engines like Elasticsearch or Solr That sounds like a huge constraint. How can you do powerful searches if you don't index the log lines? After this video, you now know how to use Loki's "filter" capability for forensic troubleshooting. Happy searching!

Grafana Loki v2.0 is here. It's an exciting feature-packed release. Loki's slogan - Prometheus, but for logs - is more true than ever before. In today's video, we'll take a quick look at my favorite top 3 features. Loki dashboard animation created by Dave Schmid

Get a sneak preview of a future version of Grafana Loki that enables you to generate ad-hoc metrics from your log data. This video features a Loki-based web analytics dashboard, which uses the access logs of the popular open-source web server NGINX. Every panel on this dashboard uses ad-hoc metrics created with Loki, well, besides the Log panel obviously. Would this be useful for your use-case? Let us know in the comments.

In this webinar, Marcus will show you how to get started using Grafana. He’ll walk you through the Grafana user interface while showing how to set up monitoring for a web service that uses Prometheus and Loki to store metrics and logs. You’ll learn how to connect, explore, and correlate data in Grafana to gain valuable insights into your application. This webinar requires no previous experience with Grafana.

Presenters will take and answer questions after the presentations in our #grafanaconline channel in our public slack:

Grafana provides a powerful and elegant way to create, explore, and share dashboards and data with your team and the world. Grafana is most commonly used for visualizing time series data for Internet infrastructure and application analytics but many use it in other domains including industrial sensors, home automation, weather, and process control.

Grafana has a robust plugin architecture built for extensibility. Visualize data from more than 40 data sources, including commercial databases and web vendors, and add new graph panels with rich data visualization options. There is built in support for many of the most popular time series data sources. It works with Graphite, Elasticsearch, Cloudwatch, Prometheus, InfluxDB and more.

Grafana Labs is the company behind Grafana, the leading open source software for visualizing time series data. Grafana Labs helps users get the most out of Grafana, enabling them to take control of their unified monitoring and avoid vendor lock in and the spiraling costs of closed solutions.
