Storing time-series data, relational or non?

Question

I am creating a system which polls devices for data on varying metrics such as CPU utilisation, disk utilisation, temperature etc. at (probably) 5 minute intervals using SNM

Answer 1

This is a problem we've had to solve at ApiAxle. We wrote up a blog post on how we did it using Redis. It hasn't been out there for very long but it's proving to be effective.

I've also used RRDTool for another project which was excellent.
