Partly. :)
We have a different scenario here: We use grafana with the archiver
datasource plugin
(https://github.com/sasaki77/archiverappliance-datasource/) to build
dashboards from archiver data. We would like to display some kind of
additional information to show if the data is actually valid. So the first
idea was to use .STAT for this (which is not available by default). Is
there any other way to access this information via the plugin?

The IOC gets its data via network using streamdevice, so the reason for an
error would rather be a timeout or communication error which would
probably not show up in available fields like HIHI,HIGH,LOW,LOLO.
