The section below lists every limit that this version of awslimitchecker knows how to check, and its hard-coded default value (per AWS documentation).
Limits with a ✔ in the "Trusted Advisor" column are comfirmed as being updated by Trusted Advisor. Note that so long as the Service and Limit names used by Trusted Advisor (and returned in its API responses) exactly match those shown below, all limits listed in Trusted Advisor "Service Limit" checks should be automatically used by awslimitchecker. However, limits marked here with a ✔ were detected as being returned by Trusted Advisor as of the last release. Note that not all accounts can access Trusted Advisor, or can access all limits known by Trusted Advisor.
Limits with a ✔ in the "API" column can be retrieved directly from the corresponding Service API; this information should be the most accurate and up-to-date, as it is retrieved directly from the service that evaluates and enforces limits. Limits retrieved via service API take precedence over Trusted Advisor and default limits.

Note on On-Demand vs Reserved Instances: The EC2 limits for "Running On-Demand" EC2 Instances apply only to On-Demand instances, not Reserved Instances. If you list all EC2 instances that are running in the Console or API, you'll get back instances of all types (On-Demand, Reserved, etc.). The value that awslimitchecker reports for Running On-Demand Instances current usage will not match the number of instances you see in the Console or API.
