👏 A big thank you to Seq for coming on board as a Silver Sponsor for DDD Brisbane 2025!

Community events like DDD Brisbane wouldn’t be possible without the support of sponsors who believe in building and strengthening the local developer community.

Seq Forwarder has moved!

Seq's own handy little store-and-forward ingestion proxy has been rewritten as the `seqcli forwarder` command group:

github.com/datalust/seq...

The original Seq Forwarder repository has been archived, but past releases will remain available there.

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 anything useful by looking at the values of a...

A peek into the delicate machinery that adapts a running Seq node to its role in the cluster: blog.datalust.co/leader-elect...

The components responsible for tracking node state and orchestrating transitions. A consensus module interacts with the external cluster state database, feeding triggers into the node state machine. Simultaneously, a clock component fires triggers in the state machine too. The state machine sends commands to a command queue, which is observed by a command queue monitor. The command dispatcher pulls commands from the queue, and orchestrates the storage engine and application components.

The Seq Events screen, showing the command palette dialog as an overlay. The dialog comprises a search box and a list of matching commands. The search box has been filled with the word "signal", and the command list shows matches including "Add to Signal", "Clear All", "Exclude", "Save", and "Signals", each with help text. Beside the matching command names are the shortcut key sequences for each command, for example Add to Signal is Ctrl Space, A.
