Setting Rate Limits on the Omnissa Access Service

You can set limits on the number of login, launch, and WS-Fed requests that can be made per minute to the Omnissa Access service. When the limit is reached, subsequent requests are denied. Setting rate limits helps prevent overload of the system.

For example, if you set the rate limit for login requests to 100, the first 100 login requests per minute are accepted but requests 101-n are denied.

For an Omnissa Access cluster, the rate limit applies to each node in the cluster. For example, if you set the login request rate limit to 100 for a cluster that has NodeA, NodeB, and NodeC, NodeA can process 100 login requests per minute, NodeB can process 100 login requests per minute, and NodeC can process 100 login requests per minute. You cannot set separate login limits per node.

When the limit is reached and requests are denied, end users see the following error message:

No rate limits are set by default.

You set rate limits using a REST API. Use a REST client such as Postman to make the calls to the Omnissa Access service. The changes take effect in a few minutes.
