AWS polling

Table of contents
No headers

To poll resources and gather metrics, multiple AWS APIs — including CloudWatch, EC2, and EBS — make requests (also known as "calls") to cloud instances and volumes.

AWS provides 1 million free requests per calendar month for each account. If you exceed that limit, your AWS account will be charged for extra requests within the remaining time frame.

The amount of polling requests that occur depends on many factors, including:

  • Polling frequency.
  • The quantity of resources being polled.
  • The types of resources being polled.

For example, monitoring a single AWS EC2 instance with a 5-minute polling interval consumes approximately 60,000 requests per calendar month; an EBS volume with the same polling interval may use 100,000 requests per month. Instances managed as nodes, third-party products, and custom code also consume requests.

Here is an overview about how the Orion Platform works with AWS to poll for metrics:

  1. Multiple AWS APIs (including CloudWatch, EC2, and EBS) poll AWS cloud instances and volumes.
  2. The EC2 web service sends metric data to the Amazon CloudWatch monitoring service.
  3. The Orion Platform polls the Amazon CloudWatch service for standard AWS metrics, plus metrics such as memory, usage, and alerts.
  4. The Orion Platform saves metric data to the Orion SQL database.

To track the quantity of API requests, you can either:

  • Display the latest amount of consumed requests in the AWS Management Console , or
  • Display approximate usage in the Orion Web Console:
    1. On the Cloud Summary page, click Cloud Infrastructure Monitoring.
    2. On the Cloud Infrastructure Monitoring page, click Manage Cloud Accounts.
    3. On the Manage Cloud Accounts and select the check box for an AWS account.
    4. Click Edit Properties.
    5. On the Edit Properties page, switch to the API Polling Options tab and examine the Approximate Requests Used this Month value.
