VIP Authentication Hub - high latencies

Products

• VIP Authentication Hub

Issue/Introduction

We have AppDynamics agent, which collects various metrics from the services. Over and over one particular call shows high latencies: /admin/v1/AuthPolicies/download

A call to this endpoint takes from hundreds of milliseconds, all the way to 11 seconds. When drilling down in the high latency call, we see many queries to the MySQL database. None of these queries looks suspicious, however, together they add too much.

VIP Authentication Hub

Resolution

The observed slowness is by design by a batch process and does not impact the response times from AuthHub. The OPA policy agent makes a service call to Admin to refresh its policies every ten minutes. It is totally a backend process and have no impact on the performance of AuthHub.
