New Revision: 338133
URL: https://svnweb.freebsd.org/changeset/base/338133
Log:
- Add CSV output to gstat via -C flag.
Add a -C option, similar to -B, that allows gstat to produce basic CSV output
with absolute timestamps (ISO 8601, nearly.) Multiple devices are handled by
way of a single-pivot CSV table with duplicated timestamps for each object
output.
