billing and limit the log size

[CyrilChu]

If we use pay-as-you-go billing model, how to calculate the cost under 1GB? Would Microsoft charge cost when the log size under 1GB? Also, can we limit the log size received? For example. if the total log size hit the daily 100GB threshold, can we stop reviewing log from the collector?

Billing is actually logged by Bytes used. So if you send 10 Bytes of billable data, that would be billed as a proportion of the per GB listed on the pricing site https://azure.microsoft.com/en-us/pricing/details/monitor/
e.g. if you think 1GB/day == $2.30 and you only send 0.5GB, you will be charged $1.15 etc...

You can set a billing cap https://docs.microsoft.com/en-us/azure/azure-monitor/logs/manage-cost-storage#manage-your-maximum-da...
