Monitoring an Amazon CloudSearch Domain with Amazon CloudWatch

Amazon CloudSearch automatically sends metrics to Amazon CloudWatch so that you can gather and analyze performance statistics. You can monitor these metrics by using the Amazon CloudSearch console, or by using the CloudWatch console, AWS CLI, or AWS SDKs. Each of your domain's search instances sends metrics to CloudWatch at one-minute intervals. The metrics are archived for two weeks; after that period, the data is discarded.

There is no charge for the Amazon CloudSearch metrics that are reported through CloudWatch. If you set alarms on the metrics, you will be billed at standard CloudWatch rates. You can use the metrics in all regions supported by Amazon CloudSearch.

Not all statistics, such as Average or Sum, are applicable for every metric. However, all of these values are available through the Amazon CloudSearch console, or by using the CloudWatch console, AWS CLI, or AWS SDKs for all metrics. In the following table, each metric has a list of Valid Statistics that is applicable to that metric.
