Are members in your organization running any sort of analysis (e.g. geocoding, analysis tools in the map viewer, etc.)? See the link below for a list of all ArcGIS Online functionality that uses credits:
Additionally, can you share screenshots of the Status tab of your ArcGIS Online organization so I can get an idea of how much it fluctuates?
Hi, thank you for your response.
No one is doing any sort of analysis on ArcOnline. 100% of our credits go toward storage. I do have a screenshot attached to the original question. Do you want more than that? I wasn't sure what to include. It looks like we fluctuate between 5 and 10 credits at times.
Sorry, I didn't see the screen shot!
So I definitely see fluctuation but from day-to-day, it looks like the fluctuation is less than 5 credits in every case besides the last day.
In the Status page of your organization, you can view credit usage by individual items. I would go through and see if you can find a service that seems to be fluctuating and monitor the credit usage and edit history for the next few days to see if you see anything unusual.
