Robots do not failover to another hub when their primary hub is down

Issue/Introduction

We are in the process of testing a inplace OS upgrade on our Secondary hubs and noticed that some robots are not failing over to another hub when the hub is down.

Also noticed that these robots are not collecting metrics when they do not failover to another hub

How can we configure robots to failover to another hub?

Environment

Any UIM version

Resolution

1. Create a robot superpack with settings to failover to a specific hub 

See Simple UIM superpackage

Example of .cfx file

<controller> overwrite
   secondary_domain = uimdomain
   secondary_hub = primaryhub
   secondary_hubrobotname = myprimaryhub
   secondary_hubip = #.#.#.#
   secondary_hubport = 48002
</controller>

2. Deploy the superpack to a few robots for testing

3. Stopped the Nimsoft Robot Watcher service on the secondary hub

4. Waited and confirmed that robots temporarily failed over to the secondary hub

5. Start the Nimsoft Robot Watcher service on the primary and confirmed that robots moved back to the Primary

6. Deploy the superpack to all robots

7. Proceed with OS upgrade on Primary hub
