gearman_gtop's Issues

Filter by Wildcard / Regex

There are times when I want to filter by a wildcard / regex, currently attempting to filter by either returns the following error:

$ gearman_gtop -sort=2 '-filterInclude=ekm.+Order' '-filterExclude=fail,stale'

-q quiet (by default?)

gearman_top has a -q option for hiding inactive queues (no workers or jobs). This is useful, as while scrolling is big +, not having to is usually more useful for development.
