I use a few PowerShell scripts that end up triggering Service Management Automation (SMA) runbooks. Each time you want to use PowerShell to do that, you end up creating a one-time use SMA schedule. These one-time schedules are eventually cleaned up by SMA but they can clutter your view pretty well if you have a lot of them.

Luckily, there’s an easy way to use PowerShell to list SMA schedules that aren’t one-time use. We just want a list of all the SMA schedules that are repeating. You need the SMA PowerShell tools for this.

Get-SmaSchedule -WebServiceEndpoint https://SMA-Management-Server | ? { $_.NextRun } | ft

We’re going to get all the SMA schedules on our SMA implementation and get the ones where there is a NextRun value. The question mark is an alias for the Where-Object command and so we’re looking for schedules where $_.NextRun is true (has a value, isn’t null). I like formatting the output as a table for easier reading.

If a schedule has a NextRun attribute, it’s safe to say that it’s going to run sometime in the future and is not a one-time use schedule that’s already done it’s job.
