Splunk has a predict command that can be used to predict a future value of a metric based on historical values. This is not a Machine Learning or an Artificial Intelligence functionality, but a plain-old-statistical analysis.
So if we have a single metric, based on historical results we can produce a nice prediction for the future (of definable span), but predicting multiple metrics in Splunk might not be as straightforward.
I started playing for Splunk Metrics rollups and but then tried to step out of the box and got a “Failed to apply rollup policy to index=’…’. Summary span=’7d’ cannot be cron scheduled” error.
