Orchestrator API Limit for 'Aruba url' was exceeded

By default, SolarWinds Hybrid Cloud Observability limits API requests for Aruba orchestrators to 250 requests per 5 seconds. SolarWinds Hybrid Cloud Observability does not send more requests than the limit by default. If the limit is exceeded, you will receive an Event and the Details widget on the Orchestrator Node Details page will inform you that the Aruba Polling limit was exceeded. See Resolution for tips on how to limit the requests.

Overview

An Aruba Orchestrator is limited to 250 requests per 5 seconds. By default, SolarWinds Hybrid Cloud Observability does not send more requests than the limit. If the limit is exceeded, you will receive an Event and the Details widget on the Orchestrator Node Details page will also inform you that the Aruba API polling limit was exceeded. See Resolution for tips on how to limit SolarWinds requests.

Cause

This issue occurs because the maximum number of allowed Aruba API requests was exceeded. Starting in Aruba Networking Central 2.5.8, Aruba allows one access token every 30 minutes.

Resolution

Please upgrade to SolarWinds Platform 2024.4.1 and above as additional enhancement were made to help prevent the Aruba API limit from being reached.  If you cannot turn off the additional sources of API requests, consider configuring additional limits to be enforced in SolarWinds Hybrid Cloud Observability.

 

Important!

  • SolarWinds is recommending to create a unique API key for the SolarWinds Platform.  Sharing API keys across different application will increase the chances for the rate limit setting by Aruba.  If the same API key is utilized by different applications within 30 mins, this will cause SolarWinds polling to fail due to the lockout.

Configure additional limits

  1. Log in to the SolarWinds Platform Web Console using an account with administrative privileges.
  2. Copy /Admin/AdvancedConfiguration/Global.aspx and paste it into your browser address bar, after /Orion. See Access the Advanced Configuration settings in the Orion Web Console.
  3. Now in Advanced Configuration Settings, search for Orchestrators.Aruba.
  4. Adjust the responses caching to share responses to similar requests between polling jobs on your polling engine. Increase values for the following settings to reduce the number of requests sent to the API.
    • InventoryRequestsCacheTimeToLive: Time to live for inventory requests cache item. The default value is 5 minutes.
    • PollingRequestsCacheTimeToLive: Time to live for the polling requests cache item. The default value is -1 minute, which means that TimeToLive is equal to the polling interval of a poller that makes the request.
  5. Adjust the rate limits on the SolarWinds Platform side to control how many API calls the platform performs within a specific time. If appropriate, change the number of requests per second to a smaller number.
    • RequestMaxWait: Specifies the time the rate limiter waits for a free execution slot before the request fails. The default value is 1 minute, formatted as 00:01:00. If appropriate, decrease the wait time. To configure requests to fail when there is no free execution slot, enter 00:00:00.
    • RequestRetries: Specifies how many times a request is resent if it fails. The default value is 2.
    • RequestsLimit: Limits the number of requests to Aruba API per limitation period. By default, this is set to 250. The default value is half of the general Aruba Orchestrator requests limit to prevent possible overloading of the Aruba Orchestrator API. Reduce this setting to reduce the number of API requests.
    • RequestsLimitationPeriod: The limitation period. By default, this is set to 00:00:05 (five seconds). Make the limitation period longer to reduce the number of API requests.
