We use unit tests running from our CI server as synthetic transactions and have business transactions that track them. If the CI server is having issues then we don't have measurements in the required time frames and charting doesn't display as expected.
I'm looking for a way to display a banner message on all open dashboards that there is an issue with the CI without having to add a dashlet individually to every dashboard. Is this doable?
edit(11/11): ps: I want to do this when in kiosk mode.
The best option would be to use heat field in chart dashlets.
Use some way to monitor your CI server using dynatrace either agent based or using some plugin monitors.
create an incident based on the monitor and select that incident in the heat field.
i have not provided the exact steps but i hope you got the idea.
