Keith,
For Aggregate Space Summary report ,there are no graphs available. I mean,for some of the reports graphs are available ( for example under Monitoring if you choose capacity , then you will find Aggregate Capacity Graph), some reports are graph based, some are not. I would recommend to use the Aggregate Capacity Graph where you can see the trend between used vs total for each of the aggregates.
If you click the specific aggregate it will give more details of that aggregate and you can select the time period which you want to see the trend( say 1m or 3m period)
You can schedule the reports according to your convenience, click on the clock icon button on the extreme upper right hand side on the report page, once done it will take to schedule page and you can schedule the reports by clicking manage schedules after filling in the details.
>> You can even go to Oncommand UI dash board NMC and there click the reports section --> Detailed Reports-->Storage Capacity ( under this section you can choose the reports of interest and then schedule accordingly).
In simple logic the daily growth rate is calculated in the following way :
1) The fsMonInterval which is set for 15 minutes keeps polling the filer ( fsmon engine code will poll the filer every 15 min by defualt as configured ) and will have the data stored in the data base in cumulative way.
say for a particular time period in a day of 24 hrs, it will have the cutoff time to caluculate the growth rate percentage for that day based on the previous days growth rate.
The data from the previous days - the current cut off day / the whole ( previous days data rate change + current day data rate change)
Please let me know if you still have any concerns on the same, if you still need some further clarification ,I can set up WebEx and will walk through the reports/schedules .
