How to change retention duration for Azure Application Insights?

Question

At the moment most of the data retained for 90 days by default. I was wondering if there way to change this setting to 30-40 days. I know that I can export them to keep the data longer but what I'm looking for is mainly keep the data for shorter duration for the upcoming regulations.

Answer 1

Sometimes the only answer is a no. In this case, you can't. From the docs:

Raw data points (that is, items that you can query in Analytics and inspect in Search) are kept for up to 90 days. If you need to keep data longer than that, you can use continuous export to copy it to a storage account. Aggregated data (that is, counts, averages and other statistical data that you see in Metric Explorer) are retained at a grain of 1 minute for 90 days.

I remember that a long time ago the pricing tier dictated the maximum retention period but it is now fixed to 90 days for all plans.

Update

The default retention for Application Insights resources is 90 days. Different retention periods can be selected for each Application Insights resource. The full set of available retention periods is 30, 60, 90, 120, 180, 270, 365, 550 or 730 days.

Note: If you need to keep data longer than 730 days, you can use Continuous Export to copy it to a storage account during data ingestion.

To change the retention, from your Application Insights resource, go to the Usage and Estimated Costs page and select the Data Retention option:
