Performance Overview "Last Day" view fails to render within 24 hours of changing statistics intervals from 1 to 5 minutes.

Products

• VMware vCenter Server

Issue/Introduction

• The interval duration was left at 1 minute for more than 24 hours of vCenter server.
• The Performance Overview graph (Last Day view) fails to display data after the statistics interval duration was changed from 1 minute to 5 minutes.
  The statistics interval was modified via vSphere Client > vCenter Server > Configure > Settings > General > Statistics > Interval Duration (changed from 1 minute to 5 minutes).
  
• The performance graph stopped rendering data from the point of the configuration change onward.
  vSphere Client > Object (e.g., ESXi host) > Monitor > Performance > Overview > Period: Last Day.
  
• When exporting to CSV, the data shows a transition from 1-minute intervals to 5-minute intervals, with empty entries in between:
  
  exported.csv
  "yyyy-mm-ddT05:31:00.000Z",***,***
  "yyyy-mm-ddT05:32:00.000Z",***,*** <= (1-minute interval)
  "yyyy-mm-ddT05:33:00.000Z",,
  "yyyy-mm-ddT05:34:00.000Z",,
  "yyyy-mm-ddT05:35:00.000Z",***,***
  "yyyy-mm-ddT05:36:00.000Z",,
  "yyyy-mm-ddT05:37:00.000Z",,
  "yyyy-mm-ddT05:38:00.000Z",,
  "yyyy-mm-ddT05:39:00.000Z",,
  "yyyy-mm-ddT05:40:00.000Z",***,*** <= (Switched to 5-minute interval)
• Values recorded at 5-minute intervals can be checked by hovering the mouse over the display.

Environment

VMware vCenter Server 7.*
VMware vCenter Server 8.*

Resolution

This is expected behavior and the issue will resolve itself automatically once 24 hours have passed since the configuration change. At that point, the "Last Day" window will consist entirely of 5-minute interval data.

To view performance data before the 24-hour period has elapsed, use the advanced performance view with a custom interval (available 1 hour after the change):
vSphere Client > Object (e.g., ESXi host) > Monitor > Performance > Advanced > Chart Options > Custom Interval.
