BIRT-Trend Timestamp values of SCM Snapshots FILE_ADDITION_C
Hi,
I would like to create a line type chart to show the evolution of number of files added to a particular component during last week. Although I am able to create that graph all FILE_ADDITION_COUNT values are just for the last day I updated all snapshot data in the datawarehouse but it does not store history of previous values. It seems that the datawerehouse only stores values for last update and older values in tables taken in previous days are deleted. Is this true? Is there any way to create this reports accessing to other data? Thanks, ana |

Hi, problem was that all changes performed during the same day (although I updated the datawarehouse several times during the day) are stored with the same hour 1.00 AM. But history of changes are stored. Thanks, of files added to a particular component during last week. |

I understand that aggregating SCM data can consume a lot of resources and should be done only when users are not working. But my main concern is that the timestamp values (or additional column data related with month, day...) should represent the real values when change sets were created or delivered to streams in RTC. Otherwise the reports may not represent real values if snapshots are not taken frequently (i.e, although change sets may have been delivered February 22 if the snapshots do not run during February 21 the report looks like if I had not delivered anything to the stream that day but it was delivered). I.e, a report that shows the amount of change sets delivered to each streams are critical for continuous integration metrics and although I am able to create it with BIRT the values depend if I create or not snapshots each day. Thanks again, Ana |

Collecting this data would be much different than the data that we're currently collecting (which basically relies on taking a point-in-time look at the stream and doing a delta from the previous collection). So basically, this isn't possible with any of the collection code we have. In 3.0, we're working on a set of REST API that may make it easier to collect this data, and a more extensible data warehouse. At that point it might be possible to do this. james RTC Reports Team Lead |
