We believe the Grafana-based approach requires the measurements being displayed to all be in a common archive.  Is this the case, and if so is there now a lesser value in local archiving on the measurement point?

 

The only value in archiving locally is if people want to be able to see that system’s measurements and don’t have access to a central archive they can query as they see fit.  I’m pretty sure Grafana is capable of joining queries from multiple data sources, but pulling data from a whole fleet of small archives for each query isn’t very efficient.

 

If we wish to have a recurring test archived to two separate archives, can this be done without running the test twice? In particular, if the host’s tests are scheduled via a separate psconfig run to generate tests for each archive, what’s the optimal way to do this to avoid repeated (duplicated) tests?

 

Yep, easy:   Run one task and specify as many archives as you need.  This feature is part of the pScheduler task specification and is supported by pSConfig as well.
