Hi there - is there any way to do predictive alerting in Prometheus? 

ie. send me an alert 3 days before my disk in use on a particular machine (or group of machines) will reach 90%. Basically looking for some way to do alerting based on what is likely to happen in the future based on some extrapolation.

Yes - an example of what you're looking for is outlined here.

Hi Conor - that seems to be an invalid URL in the hyperlink. Can you send the URL?

Thanks, this is exactly what i was looking for!! 

Is there any configure these alerts via the UI, or is code the only way to do it? Are there other functions for non-linear prediction/extrapolation for alerting or just predict_linear()? Sorry for the many questions, and thank you for the quick responses!

We only have configuration via the files.  Most users check these kinds of things into source control and/or deploy them with some kind of configuration management that pairs with the server deployment.

The only function we have is predict_linear() currently. We're open to additional functions, but there hasn't been a lot of interest.

Thank you! 

we haven't yet set up Prometheus as of yet, do you happen to have a screenshot of what context we would be shown after a this predict_linear() alert is fired?

Generally, Prometheus alerts are only so-so at providing context by themselves, because of how they work. For predictive alerts this is even worse, because it only provides info like "in 24h this disk will be 109% full".

Instead, you can create templated Grafana dashboards with the context you *want* to see and use annotation templates to construct a link to the dashboard for this instance/disk/cluster.
