¥ 0.0622 per 1,000 GetMetricStatistics, PutMetricData or ListMetrics API requests

¥ 0.0651 per 1,000 metrics requested using GetMetricData API*

*The price for requesting one metric using GetMetricData API is ¥ 0.0000651 and you can request up to five statistics for the same metric in a single GetMetricData API without additional charges.

CloudWatch Metric Streams pricing is based on the number of metric updates. A metric update includes four default statistics; Minimum, Maximum, Sample Count and Sum. Each additional five statistics requested for a specific metric, are billed as an additional metric update. You will also incur additional Amazon Kinesis Data Firehose charges for data ingestion --- for details see the Kinesis Data Firehose pricing page. You may also incur additional charges depending on your use case and final Kinesis Data Firehose destination. For example: (1) when sending data to a HTTP endpoint or cross-region, data transfer out from CloudWatch Metric Streams is priced equivalent to the "Data Transfer OUT from Amazon EC2 to Internet" and "Data Transfer OUT from Amazon EC2 To" tables on the EC2 pricing page, and (2) when making additional format conversions within Kinesis Data Firehose, such as configuring your Firehose delivery stream to convert the incoming data into Apache Parquet.

Metric Streams Pricing: ¥ 0.01953 per 1,000 metric updates using Metric Streams

Amazon CloudWatch cross-account observability, an addition to CloudWatch’s unified observability capability, introduces two account categories: Monitoring account and source account. For details, see the Amazon CloudWatch cross-account observability documentation.

Amazon CloudWatch cross-account observability comes with no extra cost for logs and metrics. CloudWatch delivers the first trace copy stored in the first monitoring account with no extra cost. Any trace copies sent to additional monitoring accounts are billed to the source accounts for the traces recorded based on Amazon X-Ray pricing. Standard CloudWatch rates apply for the features used in monitoring accounts, such as CloudWatch Dashboards, Alarms, Logs Insights queries or Metric Streams.

Data Transfer OUT from CloudWatch Logs is priced equivalent to the “Data Transfer OUT from Amazon EC2 To” and “Data Transfer OUT from Amazon EC2 to Internet” tables on the EC2 Pricing Page.

* There is no Data Transfer IN charge for any of CloudWatch.

Vended logs are logs that are natively published by Amazon Web Services services on behalf of the customer. VPC Flow logs is the first Vended log type that will benefit from this tiered model. However, more Amazon Web Services Service log types will be added to Vended Log type in the future.

Container Insights introduces enhanced observability for Amazon EKS that enables to opt-in at cluster level to collect container level EKS performance metrics, Kube-state metrics, and EKS control plane metrics out-of-the box, using a new, observation based tiered pricing model. An observation corresponds to a data point ingested at a single timestamp and unifies the existing two price dimensions of metric storage and logs ingestion into one.

In Container Insights with enhanced observability, you will be charged based on the number of observations across your container environment where the total number of observations ingested is dependent on your container set-up including the number of container components. At a typical set-up your average distribution for observations will be

Container Insights metrics are ingested in structured performance logs format and extracted into CloudWatch as Custom Metrics

CloudWatch metrics

CloudWatch metrics are aggregated by pod, service, and namespace using their name. Increasing the count of running instances will not impact the count of CloudWatch metrics generated. All CloudWatch metrics are prorated on an hourly basis and charged by custom metric pricing. There is a predefined number of metrics reported for every cluster, node, pod, and service

CloudWatch Logs

For Kubernetes, there is an average logs size ingested for every cluster, node, namespace, pod, container and service. 

The cost of logs ingested will vary based on names used for your cluster, container, pod, service, instance names, labels, etc and charged by custom logs ingestion pricing.

Container Insights introduces enhanced observability for Amazon ECS which enables you to opt-in at the cluster level or account level to collect task and container-level ECS performance metrics out-of-the box. All Container Insights metrics are ingested in Embedded Metric Format (EMF) leading to 3 billing dimensions: Logs Ingestion, Logs Storage and Metrics Storage. Container Insights with enhanced observability for ECS is priced per metric, per month, prorated by the hour, and unifies the two price dimensions of metric storage and logs ingestion into one. Logs storage is charged separately. Container logs also continue to be billed per standard CloudWatch logs storage and logs ingestion pricing.

CloudWatch Database Insights consolidates database metrics, SQL query analytics, and logs for Amazon Aurora and RDS databases into a unified experience in CloudWatch. Pricing is based on the amount of compute resources used by the monitored databases. For provisioned instances, you are charged hourly based on the average number of vCPUs used per instance. For Amazon Aurora Serverless v2 databases, you are charged hourly based on the average number of Aurora Capacity Units (ACUs) monitored per instance.

Database logs continue to be billed separately based on standard CloudWatch Logs storage and ingestion pricing.

Example 11 - Alarming with composite alarms

Composite alarms can combine any type of CloudWatch alarm. Metric alarms are billed based on the number of metrics per alarm, while composite alarms are billed per alarm unit. One composite alarm costs ￥3.480 per month, regardless of the number of metric alarms it combines.

If you create one composite alarm that combines four standard resolution metric alarms, your monthly bill is calculated as follows:

Four standard resolution alarms = ￥0.622 per alarm metric * 4 = ￥2.488 per month

One composite alarm = ￥3.480 per month

Monthly CloudWatch charges = ￥2.488 + ￥3.480 = ￥5.968 per month
 

If you monitor 1 Lambda function that is invoked 1M times per month, your costs would be as follows:

CloudWatch metrics
There is a predefined number of metrics reported for every function. Every function reports 8 metrics. CloudWatch metrics are aggregated by function using their name. All CloudWatch metrics are prorated on an hourly basis. If your function is invoked less than once per hour, your function will only be billed for the hours that it is invoked.

There are no minimum fees or mandatory service usage. If the function is not invoked, you do not pay.

Monthly number of CloudWatch metrics per function
= 8 metrics * 1 function
= 8 CloudWatch metrics

Monthly CloudWatch metrics costs = ¥ 2.0000 per metric for first 10,000 metrics * 8 metrics = ¥ 16.0000

Once you exceed 10,000 total metrics in your account then volume pricing tiers will apply. See metrics pricing for details.

CloudWatch Logs
A single log event is generated for each function invoke. The size of each log event is approximately 1.1 KB.

Monthly GB of CloudWatch Logs ingested = (1.1 KB/1024/1024) GB * 1,000,000 invokes per month = 1.05 GB per month 

Monthly ingested logs costs = ¥ 6.2280 per GB of ingested logs * 1.05 GB of performance events as CloudWatch Logs = ¥ 6.5390 per month

Monthly CloudWatch costs = ¥ 16.0000 + ¥ 6.5390 = ¥ 22.5394 per month.

Monthly ingested logs costs = ¥ 6.92 per GB of ingested logs * 1.05 GB of performance events as CloudWatch Logs = ¥ 7.2660 per month

Monthly CloudWatch costs = ¥ 16.0000 + ¥ 7.2660 = ¥ 23.2660 per month.
