Analyzing the distribution of elapsed time and other telemetry metrics
Telemetry data often includes numeric values that change over time. This is roughly the definition of an observability 'metric'. It is difficult to infer »
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 »
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 »
Data Replication in Seq Clusters
Now that we've seen how Seq clusters coordinate the leader and follower roles, let's look one layer further down the stack. Log »
What's new in seqcli?
It's been a while since we posted an update on Seq's hard-working command-line client, seqcli. The 2025.1 build has just been »

We spent the past 12 months making Seq HA-capable and able to scale work out across multiple nodes. This post is the first of three that »
Announcing Seq 2025.1
TL;DR: Seq 2025.1 is here! If you're upgrading machines in a disaster recovery (DR) configuration, take note of the requirements for this »
It's time to prepare for Seq Clustering!
Now in preview, Seq 2025.1 introduces high availability (HA), scale-out clustering in the Datacenter subscription tier. * Seq 2025.1 clusters continue ingesting data and serving »
