MC - Statistics Monitoring missing data

Products

• SG-S400

Issue/Introduction

Management Center Statistics Monitoring data can be randomly missing

Environment

Management Center 3.X

Cause

The issue is rare. It may happen that database partition is created on MC and gets a successful return status from the database, but for some unknown reason the partition is actually not present in the database.

Our code then incorrectly caches the partition's existence. 

Resolution

There are some code changes to make the service more resilient, with better retry mechanisms, and more reliable when trying to ensure the partitions in the database exist with the Management Center 4.1.2 version.
