Enable tracing for one individual Analysis
On a highly loaded system with thousands of analysis i have one analysis that is misbehaving, missing executions but no skipped count, etc. Currently tracing enables tracing for ALL analysis creating an ocean of logging to plough through for that one event every few days.
As an AF administrator i would like to turn on Tracing for one or more individual analysis to investigate rare issues that happen over time, without logging ALL analysis evaluations as 99.9999% runs fine.

Not for this item yet. I did for another client, so i'm quite up-to-date with the release notes.
We are planning an upgraden soon though.
Based on your description, it is possible that you may have run into a bug that we fixed in AF 2018 SP2. Have you contacted tech support on this?
In response to Stephen Kwan, "AF 2018 SP2 will have programmatic acces..."
In this case it's not a problem that i have lagging issues, skipped count is 0 on an evaluationcount of >1B. However i have missed Evaluations as i am missing data points that preview/backfill does reproduce and i can't find the reason why. The parameters don't tell me why one specific analysis fails once every thousand evaluations or so and that's where one would need tracing.
AF 2018 SP2 will have programmatic access to PI Analysis Service run time status. With a bit of development work, you'd be able to build a dashboard for your analyses based on parameters such as lag. Hopefully that would help you NOT have to look at trace logs.

This is a great suggestion and will making analytics support much more better.
