Cosmos DB usage spike tonight

We have a Cosmos DB instance and saw a large and unusual spike in data usage tonight. After the spike, the data usage went back to a level significantly higher than before. How can I find out whether this was due to Azure doing something or whether we somehow triggered this ourselves (this seems unlikely with what I know of our backend).

Hi @matthijshakfoortrotra-4757,

Thanks for using Microsoft Q&A !!
Can you please look at other metrics like if the inserts have increased or larger replaces are happening as data size can automatically increase to accommodate increase.
I would also suggest to please create a support ticket so that an engineer could look into your environment to better understand spike's cause. In case you have any limitation to create a support case please let me know.

Thanks
Saurabh
