get-stat cpu.usage.min

[rt7500]

I have a need to gather performance data from my clusters.

I can gather cpu.usagemhz.average & mem.usage.average just fine.

What I can not do is gather the cpu.usage.min ,cpu.usage.max , mem.usage.min & mem.usage.max for the clusters.

In the VI-Tookit Cmdlet Reference is shows the "cpu.usage.min" in the detailed descriptions. So I assume this is possible.

Can anyone provide me a sample of how to gather these min/max metrics?

The min/max metrics require at least Statistics Level 3.

Do you have at least one of the four historical intervals set with at least level 3 ?

If yes, you can get the min/max metrics for that specific interval with the Get-Stat cmdlet.

That's the issue. I was thinking since I can see this data in the VIC that I could pull it with the VI-Tookit.

In which interval can you see min/max metrics in the VIC ?

Real-time (which is not a historical interval and has all metrics), Past Day, Past Week, Past Month or Past Year ?

[rt7500]

In the performance tab for the cluster there is a Maximum/Minimum heading.

Ok, I understand.

We were talking about 2 different things here.

1) there are metrics that have a min or max extension. For example cpu.usage.min.

This returns the actual minimim or maximum value the cpu usage reached during the interval.

2) for a specific metric (cpu.usagemhz.average in your screenshot) you can list the minimum and maximum value the average metric had over a series of values.

This is something you could do by piping the Get-Stat results (of cpu.usagemhz.average) to the Measure-Object cmdlet and ask for the -Minimum and -Maximum values of the series.

Do you see the difference ?
