What is Prometheus Alertmanager?

Alertmanager is rebuilding its internals in the open, and 0.34 makes operators update their dashboards.

Alertmanager handles deduplication, grouping, silencing and routing of alerts from Prometheus. The 0.34.0 release adds templatable labels on alert routes, server-side state filters on the silences API, and splits authError and rateLimited out of the generic clientError reason on the notification failure metric — a change that breaks any dashboard or alert matching reason="clientError" for 401, 403 or 429 responses.

What is b3doc?

A small B-Cubed utility for turning R Markdown into publishable docs

b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.

Prometheus Alertmanager vs b3doc: editorial side-by-side

P2.5

Alertmanager is rebuilding its internals in the open, and 0.34 makes operators update their dashboards.

◆ Current state

Alertmanager handles deduplication, grouping, silencing and routing of alerts from Prometheus. The 0.34.0 release adds templatable labels on alert routes, server-side state filters on the silences API, and splits authError and rateLimited out of the generic clientError reason on the notification failure metric — a change that breaks any dashboard or alert matching reason="clientError" for 401, 403 or 429 responses.

◆ Where it's heading

The last three minor releases show a project willing to break its own surfaces to fix its structure. Version 0.33.0 replaced the global alert marker with per-aggregation-group markers, removed the alertmanager_marked_alerts metric, and moved several types out of public packages; 0.34.0 continues by making a metric label more precise at the cost of existing queries. The structured event recorder, introduced behind a feature flag in 0.33.0, keeps accumulating output types and detail, which is the clearest signal of intent here — Alertmanager is building a first-class record of its own routing decisions.

◆ Prediction

The event recorder is the thread most likely to advance next, given it has gained outputs and event detail in each of the last two releases and remains behind a feature flag. Expect it to stabilise before the flag comes off.

A small B-Cubed utility for turning R Markdown into publishable docs

◆ Current state

b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.

◆ Where it's heading

The direction is toward predictability over flexibility. The replace argument arrived in 0.2.0 generalising the earlier logo-specific behaviour, then 0.3.0 pulled regex support back out of it because escape characters and over-broad matches caused unintended edits. That is a maintainer choosing a narrower tool that fails obviously over a general one that fails quietly — a reasonable trade for a package that rewrites files in place.

◆ Prediction

Expect continued small releases driven by the documentation pipeline's needs, with output-quality defaults and front-matter handling the likely subjects rather than new functions.
