Hi again,
grafana-wtf version 0.12.0 has just been released. The program is now also available as a container image, which might make its installation more effortless, see also How to run grafana-wtf from container image.
Please note that regarding your feature request How to find unused data sources?, the corresponding subcommand has been renamed to explore datasources.
Example
# Display all data sources and the dashboards using them, as well as unused data sources.
grafana-wtf explore datasources --format=yaml
# Display names of unused datasources as a flat list.
grafana-wtf explore datasources --format=json | jq -r '.unused[].datasource.name'
New features
Other than this, two other subcommands have been added, namely info and explore dashboards. I will be happy receive any feedback or requests about improvements to them.
With kind regards,
Andreas.
