No graphics or data are displayed in performance charts.
When data is missing for a performance chart, the chart appears empty and you see the message No data available.
The causes for missing data in performance charts that are described herein are based on the assumption that the default rollup configuration for the vCenter Server system has not changed. The causes include but are not limited to the following scenarios:
Metrics introduced in ESXi 5.0 are not available for hosts running earlier versions.
Data is deleted when you remove or add objects to vCenter Server.
Performance charts data for inventory objects that were moved to a new site by VMware vCenter Site Recovery Manager is deleted from the old site and not copied to the new site.
Performance charts data is deleted when you use VMware vMotion across vCenter Server instances.
Real-time statistics are not available for disconnected hosts or powered off virtual machines.
Real-time statistics are collected on hosts and aggregated every 5 minutes. After six data points are collected for approximately 30 minutes, they are rolled up to the vCenter Server database to create the 1 Day statistics. 1 Day statistics might not be available for 30 minutes after the current time, depending on when the sample period began.
The 1 Day statistics are rolled up to create one data point every 30 minutes. If a delay occurs in the rollup operation, the 1 Week statistics might not be available for 1 hour after the current time. It takes 30 minutes for the 1 Week collection interval, plus 30 minutes for the 1 Day collection interval.
The 1 Week statistics are rolled up to create one data point every two hours. If a delay occurs in the rollup operations, the 1 Month statistics might not be available for 3 hours. It takes 2 hours for the 1 Month collection interval, plus 1 hour for the 1 Week collection interval.
The 1 Month statistics are rolled up to create one data point every day. If a delay occurs in the rollup operations, the statistics might not be available for 1 day and 3 hours. It takes 1 day for the past year collection interval, plus 3 hours for the past month collection interval. During this time, the charts are empty.
