Getting close!
One general miss is "who is this for?" - I think you need to be a little more specific in your intended audience - that might cut a few things out or let you condense some areas.

A few changes then should be good to go.
Editorial and example updates to the Prometheus + Valkey blog post: - improved punctuation and sentence clarity, clarified redis_exporter compatibility wording - bumped the docker-compose image to valkey/valkey:9-alpine - removed the embedded YouTube walkthrough video.

factual Valkey coverage.

line, including the paragraphs identified by the grep check and the joined
sentences in the final paragraph. Preserve all wording, links, formatting, and
paragraph structure; change line breaks only.

| If you can't see your Valkey database or cache, it will continue to keep serving requests while its fragmentation goes unnoticed and memory creeps toward the `maxmemory` ceiling, or replicas lag behind and the first sign of trouble is often a latency spike somewhere downstream, long after the root cause started. | ||

Fix the subject–verb agreement.
Putting Valkey and Prometheus provides has an incorrect verb form. Use Putting Valkey and Prometheus together provides or Using Valkey and Prometheus together provides.

Reflows markdown in content/blog/2026-08-30-monitoring-valkey-with-prometheus/index.md for improved readability and consistency. Made minor wording clarifications (Prometheus uses local storage by default; Alertmanager is optional), expand explanatory notes (redis_exporter namespace), and tighten phrasing across BetterDB, redis_exporter, and examples.

The minimal scrape configuration targets redis-exporter:9121, but the local walkthrough defines the Compose service as redis_exporter. Docker Compose service discovery uses the service name, so a reader who combines this snippet with the documented stack will have Prometheus scrape a hostname that does not match the exporter service. Use redis_exporter:9121 here, or explain that deployments using this snippet must name their service redis-exporter.
