How to send Application Insights logs to a custom table with Auxiliary pricing tier in Log Analytics

Hello mrcode,

For your question below are the answers

1.I’ve read the documentation on how to create a custom table with the Auxiliary pricing tier - but how do I send my Application Insights logs to this custom table instead of AppTraces?

Since Application Insights typically sends logs to the built- in AppTraces table, you will need to use the Logs Ingestion API to send your logs directly to the custom table you have created with the Auxiliary plan. This involves:

• Creating a custom table with the Auxiliary plan.
• Setting up a data collection rule and using the Logs Ingestion API to send your logs to the custom table. The custom table must have the right schema set up before you can ingest data into it. You can find detailed steps regarding the ingestion API, refer the documentation.

2. Is it possible to change the pricing tier of the AppTraces table to Auxiliary? Or do I need to create a new table with the same structure?

Unfortunately, you cannot change the pricing tier of the AppTraces table to Auxiliary. The Auxiliary plan is only supported on custom tables created via the API, and you cannot switch existing built-in tables to this plan. You'd need to create a new custom table with your desired schema and the Auxiliary pricing tier.
