DPA 5.8: Setting a graph's axis and data values?
I've written a simple report in DPA to show data rates for TSM migrations over a period of time. The table form of the report easily comes out to what I want:
| Day | Sub Name | Storage Pool | Status | Rate (GB) |
|---|---|---|---|---|
| 03/05/2013 | TSMPRA03 | archivepool | success | 2.814 |
| 03/06/2013 | TSMPRA03 | archivepool | success | 2.887 |
| 03/05/2013 | TSMPRA03 | backuppool | success | 4.494 |
| 03/6/02013 | TSMPRA03 | backuppool | success | 5.536 |
However, when I try to convert this to a line chart, DPA doesn't group my data by date, sub name, storage pool, and success as I intend; I get distinct lines of data for each line of data in the table. Furthermore, the legend for each line of data includes the start-time of a migration backup, even though those were dropped with jobs were aggregated by a "Group By" operator.
The Report User Guide is maddenly terse about how line graphs are defined and manipulated.
How can I influence how the line graph groups data?
Thanks,
Nick

Hi Nick,
The way the line graph works is that the X axis is plotted using the timestamps associated with the data. I do not believe there is a way to choose what field you want to use for the timestamp. I believe this is what is causing the issue, as you want to use the date field, however it is not possible.
Thanks

Rats.
OK, time to fall back to exporting tables of data and using a tool with better graphing options, I guess -- and hope that DPA 6 somehow loosens up in this area.

Hi Nick,
Could you attach the report defintion to the thread? I would like to see if it can be written differently so that the line chart will work as you desire.
Thanks

Added to the original post.
Non-TSM shops (in other words, most of you!) will want to change the "TSM Migration" source to something else,but the logic should be similar. It's an attempt to compute daily data transfer rates, which almost certainly could be used with backup job detail records just as well, for example.

Hi Nick,
Unfortunately it does not seem possible to use a line graph, due to my earlier explanation.
I will raise an enhancement for this so that it can be considered for future versions.
Thanks

At this point, I'm not opening new incidents against 5.8; I'm telling myself all will be wonderful once we get DPA 6 installed. I will, of course, open cases against points that prove otherwise.
