Can Graylog store and analyze system metrics like RAM or CPU usage?

Hey @jerrac, welcome!

Are you looking for something like this?

We have developed a custom process which captures and send this information to Graylog, per the monitoring guidelines @jan prescribesin his very helpful blog post on the topic. There were a few gotchas for setting it up but it’s mostly straightforward. We also alert off of this data, and we can extend it to other servers if we desire.

I can describe what we did if it seems like what you’re looking for. It’s all entirely in-house developed but it wasn’t complicated.
