• Example 1 – Application observability: X-Ray tracing

  X-Ray tracing

  If you have an application which receives 2,000 incoming requests per hour and you’re using a 10% sampling rate, then your cost would be calculated as follows:

  Traces recorded

  Traces recorded per month = 2,000 requests per hour x 24 hours x 31 days x 10% = 148,800 traces

  Billable traces recorded per month = 148,800 traces – 100,000 traces in free tier = 48,800 traces

  Monthly traces recorded charges = 48,800 traces * €0.000005 = €0.24

  In addition, let’s assume you make 100 queries per day each scanning the last hour of data captured (200 traces) and retrieve the full trace data for 50 traces per query.

  Traces retrieved and scanned
  Traces scanned per month = 100 queries x 200 traces per hour x 31 days = 620,000 traces
  Traces retrieved per month = 100 queries x 50 traces per query x 31 days = 155,000 traces
  Total traces retrieved/scanned per month = 155,000 traces + 620,000 traces = 775,000 traces
  Billable traces retrieved/scanned per month = 775,000 traces – 1,000,000 traces in free tier = 0 traces
  Monthly traces retrieved and scanned charges = 0 traces * €0.0000005 = €0

  In addition, let’s assume you have enabled X-Ray insights on any or all X-Ray groups.

  X-Ray insights traces processed
  Traces recorded per month = 2,000 requests per hour x 24 hours x 31 days x 10% = 148,800 traces
  Monthly insights traces processed charges = 148,800 traces * €0.000001 = €0.15

  Your total cost per month for using X-Ray tracing equals €0.24+ €0.15 = €0.39.

  By default, X-Ray tracing is enabled at a 5% sampling rate when implementing application signals. This default tracing rate can optionally be adjusted higher or lower.

  If you monitor one application that receives 25,000 requests per minute (inbound service requests) and you are using the default 5% sampling rate, your tracing charges are as follows:

  Traces stored:

  Traces stored per month = 25,000 requests per minute 43,800 minutes per month 5% sample rate = 54,750,000 traces stored per month

  Billable traces stored = 54,750,000 traces stored – 100,000 traces in free tier = 54,650,000 traces stored per month

  Traces stored charges = 54,650,000 traces stored * €0.000005 = €273.25 per month

  In addition, let's assume you make 100 queries per day, with each query scanning the last hour of data capture compromising 75,000 traces and retrieve the full trace data for 50 traces per query.

  Traces retrieved and scanned:

  Traces scanned = 100 queries 75,000 traces per hour 31 days = 232,500,000 traces scanned per month

  Traces retrieved = 100 queries 50 traces per query 31 days = 155,000 traces retrieved per month

  Total traces retrieved and scanned = 155,000 traces + 232,500,000 traces = 232,655,000 traces retrieved/scanned per month

  Billable traces retrieved and scanned = 232,655,000 traces – 1,000,000 traces in free tier = 231,655,000 traces retrieved and scanned per month

  Traces retrieved and scanned charges = 231,655,000 traces * €0.0000005 = €115.82 per month

  Total charges for X-Ray tracing = €273.25 traces stored + €115.82 traces scanned/retrieved = €389.07 per month

  Total charges: €1,510.84 for application signals and SLOs + €389.07 for X-Ray traces = €1,899.91 per month

  In addition, you can use Synthetics. Refer to individual pricing examples for charges.
  

• Example 2 – Application observability: end user monitoring with Synthetics

  If you create five canaries that run once every five minutes, add alarms on five of the metrics generated by the canaries and store the data for one month, your monthly bill will be calculated as follows:

  5 canaries * 12 runs per hour * 24 hours per day * 31 days per month = 44,640 canary runs

  Monthly CloudWatch charges

  Canary run charges = 44,640 canary runs * €0.0012 per canary run = €53.57 per month
  5 alarms per month = 5 * €0.10 = €0.50 per month
  Total monthly CloudWatch charges = €53.57 + €0.50 = €54.07

  Monthly additional charges

  Each canary run also runs an AWS Lambda function, writes logs and results to CloudWatch Logs and the designated Amazon S3 bucket, and creates CloudWatch custom metrics. For details on AWS service pricing such as AWS Lambda, Amazon S3, CloudWatch Logs and CloudWatch Metrics see the pricing section of the relevant AWS service detail pages.

  Lambda charges = requests charges + duration charges
  = requests from 44,640 runs * €0.2 per 1,000,000 + duration of 20 seconds * 44,640 canary runs * 1 GB memory size * €0.000016667 per GB per sec
  = €0.01 + €14.88 = €14.89 per month

  CloudWatch logs charges = collection charges + storage charges
  = collection of 0.00015 GB per run * 44,640 runs * €0.5 per GB + storage of 0.00015 GB per run* 44,640 canary runs * €0.03 per GB per month
  = €3.35 + €0.20 = €3.55 per month

  S3 charges = put request charges + storage charges
  = put requests of 44,640 runs * €0.005 per 1,000 requests + storage of 0.001 GB per run * 44,640 canary runs * 1 month * €0.023 per GB per month
  = €0.22 + €1.03 = €1.25 per month

  CloudWatch Metrics charges = 3 CloudWatch Metrics (SuccessPercent, duration, failed) = 3 metrics x €0.30 per metric per month = €0.90 per month

  You can choose to configure additional metrics in your canary scripts: executeHttpStep() and executeStep() metrics and will be charged at customised CloudWatch Metrics rates.

  Additional monthly charges = €14.89 + €3.55 + €1.25 + €0.90 = €20.59 per month

  Total monthly charges = €54.07 + €20.59 = €74.66

• Example 3 – Application observability: CloudWatch

  If your application has 500,000 visits in a month, and you’re collecting CloudWatch events at 100% sampling for page load performance and errors with 20 data events – including one start event, one page view event and 10 performance events (three web vitals, one paint, one navigation, five resource loads) and eight errors per visit – your charges would be as follows:

  Total number of data events = 20 data events/visit * 500,000 visits = 10,000,000 data events
  Charges for 10,000,000 data events @ €1 per 100,000 data events = 10,000,000* €1/100,000 = €100

  Monthly CloudWatch data events charges = €100 per month
