Amazon CloudWatch pricing

Paid tier

Pricing examples

• Example 1 - EC2 Detailed Monitoring

  If your application runs on 10 Amazon EC2 instances 24x7 for a 30-day month, and you published 5 custom metrics every 5 minutes via the PutMetricData API, your charges would be as follows:

  Total number of metrics = 5 metrics per instance * 10 instances = 50 metrics
  Monthly CloudWatch Metrics Charges @$0.30 per custom metric = 50 * $0.30 = $15

  Total number of minutes in the month = 60 * 24 * 30 = 42,300 minutes
  Total Number of API requests = 10 instances * (42,300 minutes/5 minutes) = 84,600 requests
  First 1,000,000 API requests = $0

  Monthly CloudWatch charges = $15 + $0 = $15 per month
  

• Example 2 - Custom metrics

  If your application runs on 51,000 Amazon EC2 instances 24x7 for a 30-day month, and you published 5 custom metrics via the PutMetricData API, your charges would be as follows:

  Total number of metrics = 5 metrics per instance * 51,000 instances = 255,000 metrics
  First 10,000 custom metrics @$0.30 per metric = 10,000 * $0.30 = $3,000
  10,001 to 250,000 custom metrics @$0.10 per metric = 240,000 * $0.10 = $24,000
  250,001 to 255,000 custom metrics @0.05 per metric = 5000 * $0.05 = $250
  Monthly CloudWatch custom metrics charges = $3000 + $24000 + $250 = $27,250 per month

  Total number of API requests = 51,000 instances * (43,200 minutes/5 minutes) = 440,640,000 requests
  First 1,000,000 API requests = $0
  1,000,001 to 440,640,000 API requests = 439,640,000/1,000 * $0.01 = $4,396.40

  Monthly CloudWatch charges = $27,250 + $4,396.40 = $31,646.40 per month

• Example 3 - Monitoring with logs

  If you are monitoring HTTP 2xx, 3xx & 4xx response codes using web application access logs 24x7 for one 30-day month, by sending 1GB per day of ingested log data, monitoring for HTTP responses, and archiving the data for one month, your charges would be as follows:

  Monthly Ingested Log Charges
  Total log data ingested = 1GB * 30 days = 30GB
  0 to 5GB = $0
  5 to 30GB = $0.50 * 25 = $12.50

  Monthly Monitoring Charges
  3 CloudWatch Metrics @$0 = 3 * $0 = $0

  Monthly Archived Log Charges (assume log data compresses to 6GB)
  0 to 5GB = $0
  5GB to 6GB = $0.03 * 1 = $0.03

  Monthly CloudWatch Charges = $12.50 + $0 + $0.03 = $12.53

• Example 4 - Monitoring VPC flow logs

  If you are monitoring VPCs that send 72TB of ingested VPC flow logs per month and archiving the data for one month, your charges would be as follows:

  Monthly Log Ingestion Charges
  0 to 10TB @$0.50 per GB = 10 * 1,024 * $0.50 = $5,120.00
  10TB to 30TB @$0.25 per GB = 20 * 1,024 * $0.25 = $5,120.00
  30TB to 50TB @$0.10 per GB = 20 * 1,024 * $0.10 = $2,048.00
  50TB to 72TB @$0.05 per GB = 22 * 1024 * $0.05 = $1,126.40
  Total Ingestion Charges = $5,120 + $5,120 + $2,048 + $1126.40 = $13,414.40
  

  Monthly Log Archival Charges (Assume log data compresses to 30TB)
  30TB @ $0.033 per GB = 30 * 1024 * 0.033 = $1,013.76

  Monthly CloudWatch Charges = $13,414.40 + $1,013.76 = $14,428.16

• Example 5 - Alarming with Anomaly Detection

  If you enable Amazon CloudWatch Anomaly Detection on 10 metrics per month and only want to alarm on 5 of those metrics, you will create 5 anomaly detection alarms. Anomaly Detection is available with standard resolution alarms only. Your monthly bill is calculated as follows:

  Total number of anomaly detection alarms = 5
  Alarms are billed based on the number of metrics per alarm. For every anomaly detection alarm, there are three standard resolution metrics per alarm. One is the actual metric being evaluated, the second is the upper bound of expected behavior, and the third is the lower bound of the expected behavior.

  One anomaly detection alarm = $0.10 * 3 standard resolution metrics per alarm = $0.30 per month
  Five anomaly detection alarms = $0.30 per anomaly detection alarm * 5 alarms = $1.50 per month

  Monthly CloudWatch charges = $1.50 per month
