Memory Page Scan

Does dynaTrace provide any Memory Page Scan information? If so, where can I find it?

Hi Anoh,

The measure is called 'Page Faults Per Second' and that is how the data is collected. Since this chart is looking at averages rather than raw data it will show decimal values. This describers the data the measure collects rather than how it is shown, so it is not a misnomer.

Kind regards, Hannah

Hi Anoh,

There is not measure for memory page scan rate (I assume the rate is what you are interested) but we do track the number of page faults for a host as indicator of memory problems.

What's the use case where you would require that metric (assuming my interpretation of you needing the rate is correct)?

Best Regards,
Roman

Hello Roman,

Yes, I am interested in the memory page scan rate. The memory of two hosts are being used heavily and we would like to pinpoint exactly the rate that may help us find the source of the issue.

Hello Roman,

What are the values of the page faults on the chart? In order words, what does scale X1 mean? I see values of 0.21 and 0.23 and it does say much about what I am looking at.

You are charting the average values for the measure, so 0.21 means that you had that many page faults on average for the resolution of you chart (depends on the timeframe - could be 1min or 15min).

Best, Roman

Roman,

Is "Page Faults Per Second" a misnomer since one can change the resolution of the chart (i.e., 1min or 15min)?
