On Python versions that perform validation of this line it fails because
of a square bracket mismatch. This is due to the single quotes being
parsed first. Fix by changing the outer string to double quotes.
OM labels() was called with an array which is then incorrectly interpreted
as a single label. Unpack it to list of arguments. While at it, make error
reporting a bit more robust.
- Allow no-value user attributes which are automatically assigned "true"
when specified.
- Make "top" attribute string "true" instead of bool true for consistency.
Testing for existence is always enough for value-less attributes.
- Don't drop leading "_" from user attribute names when storing in dicts.
Dropping makes things more confusing.
- Add "_om_skip" to scx_layered fields which don't jive well with OM.
scxstats_to_openmetrics.py is updated accordignly and no longer generates
warnings on those fields.
- Examples and README updated accordingly.
This is a generic tool to pipe from scx_stats to OpenMetrics. This is a
barebone implmentation and the current output may not match what scx_layered
was outputting before. Will be updated later.
