 Azure Cosmos DB helps provide insights into your application’s performance using the Azure Monitor API.  Azure Monitor for Azure Cosmos DB provides metrics view to monitor your Cassandra API Account and create dashboards.

 ## Availability
 The availability shows the percentage of successful requests over the total requests per hour. Monitor service availability for a specified Cassandra API account.

 ## Latency
 These charts below show the read and write latency observed by your Cassandra API account in the region where your account is operating. You can visualize latency across regions for a geo-replicated account. This metric doesn't represent the end-to-end request latency. Use diagnostic log for cases where you experience high latency for query operations.
 
 The server side latency(Avg) by region also displays a sudden latency spike on the server. It can help a customer differentiate between a client side latency spike and a server-side latency spike.

 Is your application experiencing any throttling? The chart below shows the total number of requests failed with a 429-response code. 
 Exceeding provisioned throughput could be one of the reasons. Enable [Server Side Retry](./prevent-rate-limiting-errors.md) when your application experiences high throttling due to higher consumption of request units than what is allocated.

 The system view helps show metadata requests count by primary partition. It also helps identify throttled requests. The management operation shows the account activities such as creation, deletion, key, network and replication settings. Request volume per status code over a time period.

 The Total Request Units metric displays the requests unit   usage based on operation types. 
 
 These operations can be analyzed within a given time interval, defined keyspace or table.

 The Normalized RU Consumption metric is a metric between 0% to 100% that is used to help measure the utilization of provisioned throughput on a database or container. The metric can also be used to view the utilization of individual partition key ranges on a database or container. One of the main factors of a scalable application is having a good cardinality of partition keys.
 The chart below shows if your application’s high RU consumption is because of hot partition.
