ViPR SRM Report showing Storage Group Used Capacity Delta between two days.

Hello LCS

Iam not sure if this answers your question, but if you modify the Time Management on the the Used Capacity Column , you can get multiple columns generated that can show Used Capacity for each day . For Eg the settings in the Image below will generate Used Capacity each day of the week.

Also if you have used math.Delta formula to calculate the the Delta values and if you are on a version prior to SRM 4.1 then a small change needs to be made on the formula code.

• Go into administration mode (click the gear icon) -> Modules -> Formula Editor
• Choose File -> Open Source -> Math -> Delta,java
  • Look for “ (getElapsedTime(context) * 1000), “
  • Add a “ L” behind the 1000 as shown below:
    • (getElapsedTime(context) * 1000L),
• Once you have added the “ L “, Choose File -> Save -> Save source and reload formula -> ok

I did modify one of my reports to show the Delta Values, below is the attached defenition.

Hi Vaishak,

Thank you for your response.  I had already used the Time Management in my report to provide two columns for Used Capacity (GB) , one column for each of the last two days.  I believe you can see it in the jpeg I included in my original question.

The time management I used was as indicated below.

We are on SRM v4.0.1 - does this formula modification still apply?

I am trying to attach my report xml but cannot, nor can I download your report. xml.   Not sure what the issue is there.

Hello LCS

I did realize later that you had used time management on your report, I did not take a closer look at the image initially.

If you are on v 4.0.1 then the formula modification will apply. From what I heard this fix is implemented in the next release (v 4.1) .

My report definition file would not have been approved my moderators by the time you checked, please try again, there should be a download option if you click on the link below.

To upload a file you will have to use the create option at the top, and then insert a hyperlink to that document.

Thanks

Vaishak,

I was able to download and import the report you provided.   I am wondering why the Delta for the last day does not equal the difference between the Wednesday and Thursday.  That is really the value I am looking for.

The goal is to identify the SG that is growing the fasted from a capacity used perspective.

Thanks

This is great Vaishak thanks.  It will give a the foundation to track other short term capacity usage changes.

What is the significance of adding the "L" in the formula?

Hello LCS,

Glad that it works for you, the significance of adding an L to the 1000 is to tell the function that it is a Long value and not an Int value so that it can take larger numbers.

Hi - bumping an old thread, but i need this report and the link to download the xml is dead.

Is there any chance you could provide a new link?

Thanks!
