Operator Console login and dashboards very slow after applying Secure Hub

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

I have applied the Secure Hub (aka Secure Bus) to my DX UIM environment and now logging in to Operator Console is very slow.

Additionally, loading dashboards is also very slow and sometimes they do not finish loading.

Environment

DX UIM - any version with Secure Hub (e.g. 9.34S/23.4.2S) applied

Cause

thread performance on controller

Resolution

In the robot.cfg on the primary hub, in the main <controller> section, add the following two parameters to increase the available threads for handling inbound and outbound controller requests.

This only applies to the "S" version of the robot (secure bus) and will have no impact on the "normal" robot.

proxy_wq_inbound_max_threads = 20

proxy_wq_outbound_max_threads = 20
