Chef Server SD

[José Antonio Abraham Palomo]

Hi, I hope all people here be fine, in my current job we are working with chef server, and I want to develop that Service Discovery for prometheus, but before I want to ask the community if there is a PR or someone working on it.

Thanks regards.

For Chef users, people typically implement Chef search based templates and file_sd_configs.

IMO, there's no real point into adding Chef support directly into Prometheus. Chef searches are too slow/expensive to add directly to something that might send multiple queries every 30-60 seconds.

I think you have a reason, but the goal is to be able to easily use the ability to enumerate hosts as azure SD.

Metrics don't necessarily needs to scrape every 30 seconds, for default may be more time.

Do you know about a good practice for this?

As Ben said, write out file SD files, usually using chef-client, but you can also script something else up if you want to decouple the SD lifecycle from chef-client runs. The file SD is just JSON, so that's very easy to generate in Ruby/Chef.

Because Chef queries are so slow, and Prometheus SD runs on every scrape, you need to decouple them. The file SD mechanism already provides that.
