Issue/Introduction

The nutanix probe periodically disconnects.  Loglevel=5 for the probe fills the logs with normal keep alive signals making troubleshooting difficult.

Loglevel=3 logs allow for logs to cover longer periods of time and show the following:

Aug 22 18:23:31:447 [Connection tester - 3, nutanix_monitor] Failed to connect to 10.108.100.37

Cause

Connections normally are ok and work fine.  The probe is configured to send monitoring queries through load balancing. Some of these requests fail causing the error observed in the log.

Environment

Release : 9.2.0

Component : UIM - NUTANIX

Resolution

Configure the probe to connect directly to the Prism Central server instead of going through any load balancers.
