Query large amount of data from Log Analytics

Hi all,

 

I am pretty new to the PowerBI topic and already ran in to some issues.

I am trying to query a quiet large amount of data from my Log Analytics Workspace - Unfortunatley I am reaching the log analytics API limitations of 64000000 bytes for a single query.

 

https://dev.loganalytics.io/documentation/Using-the-API/Limits

 

Therefore I wanted to create some kind of ForEach Loop to split my large query into smaller ones and append all the data to a new Table. 

For example: If I want to query the data for the past 3 days, I would like to modify the "TimeGenerated between(.....)" Kusto expression inside the loop to query the data blockwise for maybe 4 hours and afterwards append the data to the Table. The loop should run until I queried all the data for the 3 days.

 Now my questions, is this possible to do with PowerBI?

 

Thanks in advanced and best regards

Hi @Happy_Cloud 

 

Not quite understand your requirement, you might raise it to the support team for better advice:

https://powerbi.microsoft.com/en-us/support/ 

If you'd like to import the results of an Azure Monitor log query into a Power BI, you can refer to:

https://docs.microsoft.com/en-us/azure/azure-monitor/platform/powerbi 

But for the 64,000,000 bytes maximum enforced by the Log Analytics API, it's also applied in power bi. you can refer to the relevant thread:
