Answer 1

Hi SirilJoseph-5276, first of all if this is a critical business issue, you can reach out to Azure Support to explain the situation and request an exception to the one-week restriction.

While you cannot immediately change the table plan due to the one-week restriction, you can work around the limitation by creating a new table, using a different workspace, or leveraging Azure Synapse Analytics for advanced analysis. If the issue is critical, contact Azure Support for assistance.

In Azure Log Analytics, the table plan (Basic vs. Analytics) can only be changed once per week to prevent frequent switching, which could impact performance and resource allocation. Since the last update was yesterday, you will need to wait until the one-week cooldown period is over before you can change the table plan again.

However, if this is a critical issue and you need to mitigate the impact immediately, here are some alternative approaches you can consider

Create a New Table with the Desired Plan

If the data in the current table is not extremely time-sensitive, you can create a new table with the Analytics plan and start sending data to it.

Update your data ingestion pipelines or queries to point to the new table.

This avoids the one-week restriction but requires adjustments in your workflows.

Use a Different Log Analytics Workspace

If you have access to another Log Analytics workspace, you can create a table with the Analytics plan in that workspace.

Redirect your data ingestion to the new workspace temporarily until the one-week cooldown period is over.

Optimize Queries and Data Ingestion

If the issue is related to performance or cost, consider optimizing your queries or reducing unnecessary data ingestion.

Use features like data sampling, filtering, or aggregation to reduce the load on the Basic plan table.

Leverage Azure Synapse Analytics

If you are using Azure Synapse Analytics, you can export the data from Log Analytics to Synapse for further analysis.

Use Synapse's integration with Log Analytics to query and process the data in a more performant environment.

if you need Export Data to Azure Synapse set up a Data Export Rule in Log Analytics to export the table data to an Azure Storage Account (e.g., Blob Storage or Data Lake).Use Synapse Pipelines to ingest the data from the storage account into Synapse. Query and Analyze the data in Synapse using SQL or Spark pools.
