Q&A redis slow log

[kcj3054]

Question

I also want to check the redis slow log using vector. It's something like redis-vector-kafka-prometheus. In fluentbit, there are plugins that check the redis slow log, but I don't think they appear in vector. Am I just not finding it? Or is it not there?

Vector 0.60.0 does not have a built-in Redis slow-log collector. The redis source consumes Redis lists or Pub/Sub channels; it does not run SLOWLOG GET.

A workaround is an external collector that polls SLOWLOG GET and emits JSON events for Vector to ingest, for example through the exec source. The collector should track entry IDs per Redis instance to avoid emitting the same entries on every poll.

Those events can then go to Kafka. To expose them to Prometheus, first derive metrics such as a slow-command counter or duration histogram from the log events.

If you’d like native support, please open a feature request describing your use case and the logs or metrics you’d like to collect.

Please don't hesitate to followup in this thread if you have further questions.
