Published: June 18, 2025 04:46
TL;DR: Seq 2025.2 is ready on datalust.co and as datalust/seq in your Docker container registry of choice. A number of improvements were in-flight during the recent Seq 2025.1 release, but came in too late for the final cut-off date. Today's release, Seq…

Telemetry data often includes numeric values that change over time. This is roughly the definition of an observability 'metric'. It is difficult to infer anything useful by looking at the values of a metric over time. People are good at detecting patterns…
Work Sharing in Seq Clusters

We've reviewed leader election and replication in Seq clusters. While these are tricky to get right, and involve nontrivial code, they're dwarfed in complexity by work sharing, which is the basis of Seq's scale-out functionality.Seq clusters ingest data at
Introducing Heatmaps

TL;DR: Heatmaps are a great way to visualize timing data over time.The canonical visualization of two dimensional data is the bar chart. The following screenshot shows a count of events at each logging level.To view these data by minute introduces a third…
Data Replication in Seq Clusters

Published: May 28, 2025 03:02
Now that we've seen how Seq clusters coordinate the leader and follower roles, let's look one layer further down the stack.Log events and traces reach the cluster nodes via HTTP, and internally these requests are routed to the leader node. Once they reach…
