Hi,
This tool does not seem to be that popular. Maybe you can outline what
you have tried, what you intend to do and what doesn't work yet as expected?
This will increase chances that someone can help.
Note: The documented alert rule syntax is outdated. You will have to use
the modern, yaml-based syntax from the official docs for this to work
(promtool bundled with older Prometheus versions will also be able to
convert such rules).
Kind regards,
Christian
