问题
We use Cosmo DB as "MongoDB" , We have a database that is only 45MB in size, less than 10,000 documents across all collections.
We run light queries and writes each day, less than 3000 requests/day, also we run “MongoDB Dump” each night to dump the entire database to local server for backup, as said, the downloaded file is only around 45 MB, so I presume it is not too big.
In Feb 2018, we received a bill which is around £3,500 which is surprisingly ridiculous. it looks like we were being charged by number of requests which we knew but for whatever reason, for a 45MB database, we would not use that much!
I've also included 2 images that shows the usage in the last 7 days. From the metrics, it shows lots of requests made by "Others" which is still unknown; it shows very light in reads/writes.
Am I being overcharged by Azure?
回答1:
The pricing of Azure Cosmos DB is based on the provisioned RUs in your collections.
For Mongo accounts, the "Other" operations are any operation different from Insert/Update/Delete/Query/Count.
To see the details, please go to the Monitor service and select the Metrics (preview).
Then you will need to select your database account, then "Mongo Requests" as the metric, and then finally add a group by "CommandName":
You should be able to see the individual commands there.
