Azure portal reports read and/or write limits, throttling API resources
Symptoms
  • Azure portal reports read and/or write limits, throttling API resources.
  • Error "HTTP status code 429 Too many requests” or error "StatusCode: 429" appear in the azure_had.elg file or the cloud_proxy.elg file.
  • Datacenter objects take longer than expected to be updated on the Security Gateway.
  • Rules containing datacenter objects are not being updated.
Cause

For each subscription and tenant, Azure limits read requests to 15,000 per hour and write requests to 1,200 per hour. When these limits are reached, throttling begins, resulting in the "HTTP status code 429 Too many requests" error.
