Tenable.io: Concurrent Active Scan Limit
Tenable applies rate limiting and concurrency limiting to the Tenable.io API to ensure that all customers experience the same level of service. A new concurrency limit has been added for active scans. You can have a maximum of 400 active scans per Tenable.io container.
An HTTP response message with a 429 (Too Many Requests) status code is returned if you attempt to launch more than 400 scans. The response also includes a retry-after
header element that specifies the number of seconds to wait before retrying. For more information, see Concurrency Limiting and Rate Limiting.
This update applies to the following endpoints:
Endpoint | Change |
---|---|
POST /scans/{scan_id}/launch | A limit of 400 active scans per container has been added. |
Tip
To get the count of active scans in your container, use the Get scan count endpoint with the query parameter
active
set totrue
