Azure Cost Management data refresh timelines:
- Initial: It can take up to 24 hours to see cost data in Azure Cost Management after setup. It can also take up to 10 days for Azure Cost Management to collect enough data to display sizing recommendations.
- Daily: From the 10th to the end of each month, Azure Cost Management should show your data up to date from the previous day after about UTC+3 the next day.
- Monthly: From the 1st to the 10th of each month, Azure Cost Management may only show your data through the end of the previous month.
- In General: Please wait 72 hours for data to propagate from Azure to Azure Cost Management before reporting a delay.
By default, Azure Cost Management processes the data for the previous day once the full data from previous day is available. So, the previous day's data will usually be available in Azure Cost Management by about UTC+3 each day, although some data (like tags) can take an addition 24 hours to reprocess after new data reaches Azure Cost Management.
Also, at the beginning of every month, when providers finalize their billing for the previous month, data for the current month is not available for collection by Azure Cost Management. It can take between 5 to 10 days at the start of each month for the previous month's data to become final in Azure Cost Management and for currents month data to be updated regularly again. During this time you may only see amortized costs from the previous month and other costs pushed via the API, but not see the daily billing. Once the data is available again, Azure Cost Management reprocess it retroactively, so that you will see the full month’s worth of data again starting sometime between the 5th and 10th of each month.
Please also note:
As soon as your Azure accounts are discovered by Azure Cost Management, cost data is immediately provided in cost based reports for both "activated" and "un-activated" accounts. However, in order for Azure Cost Management to provide usage and performance data as well as cost data, you need to register your Azure Resource Manager (ARM) credentials to activate the account following the instructions in the article at: https://support.cloudyn.com/hc/en-us/articles/212784085-Adding-Azure-Resource-Manager
In the event there is a longer than expected delay with data populating from Azure to Azure Cost Management, Azure data is still recorded in Azure and will be transferred into Azure Cost Management via the API along with the following day's data once the connection is restored.
