NSG Flow Log time interval too short

Question

Hi experts,

May I ask if it is possible to change the log interval of NSG flow log?
From doc https://learn.microsoft.com/en-us/azure/network-watcher/network-watcher-nsg-flow-logging-overview#pricing
Logs are collected at 1-min interval through the Azure platform, which means the file will be updated every minutes.

However, the storage account is charged at transaction times. Although the price unit is writing operation per 10, 000, the price is still not low for NSG flow log if it is at 1-min interval.

For example, the amount of write operation for NSG flow log for single mac address per month will be 60 * 24 * 30 = 43,200.
May I ask if is possible to make the time interval become larger? For instance, 1-hour interval?

Or is there any way to connect the NSG team members?

Thanks, and Regards,
Shijun

Hi @Shijun Lv ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to know if there is a way to change the default 1-minute interval for NSG Flow logs.

As of now, we do not have an option to specify the interval at which the Platform collects and updates Flow logs.
