 Local commands:
 ===============

ping <mon.id>           Send simple presence/life test to a mon
                        <mon.id> may be 'mon.*' for all mons
daemon {type.id|path} <cmd>
                        Same as --admin-daemon, but auto-find admin socket
daemonperf {type.id | path} [stat-pats] [priority] [<interval>] [<count>]
daemonperf {type.id | path} list|ls [stat-pats] [priority]
                        Get selected perf stats from daemon/admin socket
                        Optional shell-glob comma-delim match string stat-pats
                        Optional selection priority (can abbreviate name):
                         critical, interesting, useful, noninteresting, debug
                        List shows a table of all available stats
                        Run <count> times (default forever),
                         once per <interval> seconds (default 1)
