- Line 10: Update the first Prometheus ecosystem link so its visible label
matches its kube-prometheus repository destination: rename the label to
kube-prometheus, while leaving the other exporter links and surrounding text
unchanged.
- Line 10: Update the redis_exporter link in the introductory paragraph to use
its canonical HTTPS repository URL instead of the relative path, while leaving
the surrounding text and other links unchanged.
- Line 53: Update the closing sentence to hyphenate “open-source” when it
modifies “ecosystem,” preserving the rest of the sentence unchanged.
- Line 39: Update the “From BetterDB” text so the entire name is wrapped in bold
markup, removing the stray unformatted leading character while preserving the
surrounding wording.
- Line 4: Update the post’s frontmatter description to avoid characterizing both
exporters as fully open; remove “open” or explicitly distinguish redis_exporter
from BetterDB’s open-core model while preserving the monitoring scope.
- Around line 44-45: Keep betterdb_cluster_slot_keys,
betterdb_cluster_slot_reads_total, and betterdb_cluster_slot_writes_total
together within a single bullet, removing the dangling conjunction caused by the
split.

Keep the slot metrics in one bullet.
The bullet at line 44 ends with and, but line 45 starts a second bullet. This creates a dangling conjunction and splits one metric list into two items. Keep all three metric names in one bullet.

- link ACL LOG to the documentation.

- can we link these other things?
- I like that we're calling out what is OSS and not, but I'm less sure if we should enumerate the features of the not OSS. Perhaps we can just say "Additional features are require a commercial agreement for production use" and just link a page for BetterDB?

I think it makes sense to publish the shallow dive (this blog post) before the deep dive. I think we should leave 60-61 out until Monitoring Valkey with Prometheus is published.

Feels tacked on. Could we put the video nearer to the top. Perhaps after the first heading?

Agreed, I added the video at the beginning and a thumbnail so it doesn't look empty. I hope is okey now!

Do we want to add more details on the why and how?
Why do you need to be able to observe Valkey metrics in docker/k8s deployments?
How do you install and configure each redis_exporter and BetterDB?
Otherwise this blog feels only about What you can do with each.

Okay. I've read this one and #637 and I think we should position this one as the leader then @Andriciuc as the follow up. So, we'll publish this one then one week later, we'll publish the deep dive.
@edithturn: please add a teaser line to yours. Something like "Stay tuned for the upcoming deep dive on metrics and monitoring." @Andriciuc once this one is published, change that line a teaser that directly links yours.

Adds a short blog post covering how to get Valkey metrics into Prometheus using two exporters:
redis_exporteras a per-pod sidecar, andBetterDBfor cluster-wide and per-slot statistics.The post is an entry point rather than a deep dive; it covers what each exporter gives you, for example, PromQL for both, version requirements for the Valkey-specific metrics, and a note on BetterDB's open core licensing.
