Refreshing the dashboard more frequently than daily

As I understand it, but default, the dashboard db (snapshots?) is refreshed daily. Is it possible to have it refresh faster than that?

Are you talking specifically about the trend reports in the dashboard?
If so, then yes, the data in those snapshots are refreshed daily. There
is no way to change the schedule, although you can run the snapshots
manually if you have the appropriate permissions (JazzDWAdmins
repository permission) by going to the Reports web ui page and selecting
"Administer Data Warehouse".

After 1.0 we will be investigating ways to make the snapshot schedule
more configurable by the user.

Balaji suggested a way you can configure this today - go to the Admin
web UI and select "Advanced Properties". Find the Data Warehouse
component. You can select the "Task Delay" for any of these in seconds
-the default is 86400 (24 hours). Set it to anything you like. Two
caveats apply;

1. Be aware that some of these tasks can be intensive, and running them
more frequently could negatively impact the people who might be working
with the server at the time.

2. When the task delay is 86400, we have magic code to try to ensure
that the snapshot runs as close to midnight as possible. For any value
other than 86400, the *time* at which the task first runs is not
deterministic, only that subsequent runs will be after the specified
interval.

Hope this helps.

Also, in addition to being intensive, some require significant storage. So please avoid running the tasks like every hour :-)

Good point Rafik... the snapshots add data to the warehouse each time.
The effect that this will have on the size of your system will depend
greatly on things like the number of work items, the number of
permutations of {severity, priority, state}, etc.
