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.
Multiple updates to content, removing Redis mentions, standardize coma paragraph mentions, update table to remove apple with oranges comparison. Signed-off-by: Dragos Andriciuc <andriciucdragos@protonmail.com>

A few changes then should be good to go.

||
| Each Prometheus server is standalone and runs independently, it relies only on: | ||
|
|
||
| - a local storage such as an HDD or SSD |

grammar nit: if you're using a colon (:) bullets are part of the sentence so bullets should end with either a , or a . (if it's the last bullet).
| - a local storage such as an HDD or SSD | ||
| - and [Alertmanager](https://prometheus.io/docs/alerting/latest/alertmanager/), which handles routing and deduplicating notifications | ||
|
|
||
| In Valkey's case there is a catch, Prometheus does not talk to Valkey natively. Valkey does not expose any metrics endpoint on its own however it does expose operational data through the [`INFO` command](https://valkey.io/commands/info/). |

Feels like this is a run on sentence? Either a comma or a period is needed.
|
|
||
| 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. | ||
|
|
||
| Putting Valkey behind Prometheus provides several advantages. |

'behind' strikes me as odd.. that makes me think of caching. Maybe something like "Valkey and Prometheus together"
|
|
||
| ### redis_exporter (Valkey-compatible) | ||
|
|
||
| [redis_exporter](https://github.com/oliver006/redis_exporter) is a long-standing, community-standard Prometheus exporter for Valkey metrics. It supports Valkey 7.x, 8.x, and 9.x. |

We should probably qualify this... "At time of writing, it supports..."
|
|
||
| services: | ||
| valkey: | ||
| image: valkey/valkey:8-alpine |
|
|
||
| The above is a complete, disposable local loop with Valkey, an exporter, Prometheus scraping it, and Grafana visualizing it. This is a hypothetical mirror of what you'd run in production, just without the TLS, ACLs, and persistence you'd want to layer on before shipping it anywhere real. | ||
|
|
||
| For a quick walkthrough, here's a one-minute video on exporting Valkey metrics to Prometheus with redis_exporter and BetterDB: |
