Logic app recurrence is happening randomly and not at the set time.

Richard Duane Wolford Jr 221

Hi, we're using the start/stop VM2 capabilities to stop VMs and then start them back up. However, the timing isn't working. We modified the logic app for the sequenced start/stop to stop at 6PM on Saturday and start at 6:30PM. However, instead of starting at 6PM, it seems to start whenever it feels like it. It was about an hour late starting last week, nothing else was running. Has anyone seen this behavior before?

hey @Richard Duane Wolford Jr thanks for the question
Can you provide some more detail here... you're using the logic app (is this standard or consumption?) with a timer trigger (is that correct?) and the logic app has actions to start / stop one or more VMs (which action are you using for this exactly)?
Happy to help you work through it if I can understand a bit more detail :)

Hi, yes it's a standard logic app. If you create an automation account, from there you can deploy the start/stop VM2 service from the marketplace, which creates the apps, a function, couple other things. Then you edit the logic app to set the recurrence, and then you place tags on the VMs. When they are run manually or even at the completely wrong time (and it's not consistently off by, say, 10 minutes; it could be 10 minutes, 12, or an hour), they complete successfully so we know it's not the MS code causing the issue, something about the scheduling is not working correctly.

@Richard Duane Wolford Jr Thanks for reaching out. If you don't specify any other advanced scheduling options, such as specific times to run future recurrences, those recurrences are based on the last run time. As a result, the start times for those recurrences might drift due to factors such as latency during storage calls. The same is documented here.

Can you please set a start date and time for the recurrence and the specific times to run subsequent recurrences and confirm if it resolves the issue.
