Public Preview: New Azure Monitor Auxiliary Logs Plan

Azure Monitor Logs is a solution for collecting, analyzing, and acting on telemetry data generated by Azure and non-Azure resources and applications. With Azure Monitor Logs you can collect, manage data models and costs, and consume different types of data.

Today, Azure Monitor Logs introduces a new plan in our multi-tier strategy for optimal consumption and cost optimization: Auxiliary Logs. Auxiliary Logs are for verbose logs and are designed to be inexpensive, while providing you with a set of capabilities to manage and consume your data.

Azure Monitor’s multi-tier strategy now supports three plans - Analytics, Basic and the new Auxiliary plan - and allows you to store all your logs in one place and retain different data types for as long or as little as you need, with a cost-effective pricing model.

With Auxiliary Logs you can:

• Optimize cost by ingesting low value or verbose logs to Auxiliary table. 
• Retain the data for up to 12 years at a low cost.  
• Use queries to access the last 30 days of your data, or search for older data using search jobs.
• Use summary rules (Preview) to aggregate data and ingest the results into a table with an Analytics plan for use in dashboards, alerts, or to run complex analysis on the aggregated data.

Visit the Azure Monitor pricing page for billing details. During the initial preview period, billing on Auxiliary Logs (ingestion, long-term retention, query, and search job) is not yet enabled. Details on the billing start date will be announced on Azure Updates, and for current users of the feature, advanced notice will be given before billing starts.

Auxiliary Logs plan is currently in public preview and is subject to some limitations, including regionality availability, as listed in our documentation.
