Balance - Sampling interval and data analysis

habas — Thu, 05 Jun 2025 05:55:44 GMT

Hi All,

I was wondering how balance is collecting and analyzing the performance counters. I didn’t see it documented anywhere, and I think it’s vital to know in order to understand that data displayed. Those were the first questions displayed by customers as well when presenting the utility.

1. What is the sample interval? Based on graphs shown by it, it seems the interval is once a round hour. Is that correct?

2. Is the data displayed simply a point-of-time picture of the performance at the sample time, an average since the last sample, or any other calculation?

Thanks.

Balance collects performance statistics every 15 minutes, and runs performance analysis at the top of the hour. Device discovery is at the bottom of the hour, except for vCenter discovery, which is dynamic (event based)

2. Is the data displayed simply a point-of-time picture of the performance at the sample time, an average since the last sample, or any other calculation?

The Performance Index and performance charts are based on the hourly analysis, some of the charts allow you to display the raw data instead.

Some more details are in this KB article.

What is the difference between Raw Data, Moving Average, and Daily Trend on various graphs in OnCommand Balance?
