Requests	(deprecated) Available Storage "Available Storage"will be removed from Azure Monitor at the end of September 2023. Cosmos DB collection storage size is now unlimited. The only restriction is that the storage size for each logical partition key is 20GB. You can enable PartitionKeyStatistics in Diagnostic Log to know the storage consumption for top partition keys. For more info about Cosmos DB storage quota, please check this doc /azure/cosmos-db/concepts-limits.
