How to stop cost occurring by Log Analytics for Azure App Gateway?

Question

Hi there folks, we wish to save cost occurring via Lag Analytics, especially from the Application Gateway standpoint.

Here's the current configuration:

WAF v2 - Detection Mode

Diagnostics enabled to send logs to Analytics Workspace.

Will disabling the diagnostics alone stop incurring cost? Or do we also have to switch to the 'prevention' mode?

Thanks in advance,

Answer 1

Disabling or reducing the logging categories will stop the cost increasing, but I'd also suggest looking at the retention interval which you can set per table.
