Greetings all,

 

I was testing out the EPICS Archiver Appliance, and I noticed that it does not accept channel filtered queries for archiving.

Here at LANSCE, we are very interested in archiving data on channels with filters similar to these (https://epics.anl.gov/base/R3-15/1-docs/filters.html) applied to them.

Just allowing the additional characters results in an error in the arch.log:

 

[PVNameDispatcherPVNameEvents 2] ERROR org.epics.archiverappliance.engine.pv.EPICS_V3_PV  - The meta get listener was not successful for EPICS_V3_PV TBGR001E01.NAME$

[Engine scheduler for misc tasks.] ERROR org.epics.archiverappliance.engine.metadata.MetaGet  - Cannot determine DBR type for pv TBGR001E01.{'dbnd':{'abs':1}}

 

I’m also not sure how to support filters that use a comma, as the archiver treats these as separate channels.

 

Does anyone have a recommendation for how to go about fixing this, and what else might need to be modified?

 

Sincerely,

Jonathan Quemuel
