Can we get a reference to the azure WAF logs highlighting the event max size we can expect ?

Question

Hi Team, We are working on Azure WAF connector. We are doing product setup for application gateway and Azure front door with WAF attached and sending that logs to event hub using diagnostic settings. We require information or reference link what event max size we can expect for logs for azure waf. And also what expected volume of data to be ingested from Azure WAF?

Hi @Akash Bankar

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

Azure WAF logs do not have a fixed maximum size limit per log entry. The official documentation does not specify an explicit maximum size for individual log events. Additionally, there is no expected volume of data to be ingested from Azure WAF, as it depends on factors such as traffic volume and configuration.

Application gateway:

Front Door: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits#azure-front-door-standard-and-premium-service-limits

If you have any further queries, do let us know.

Thanks,
