Yes, we have the 'pmc' (PTP managment client) for that.  You can query
the local node via UDS or the entire network via normal PTP managment
messages.  The program has both interactive and command line modes.

Some of the queries are:

CURRENT_DATA_SET           for offsetFromMaster and meanPathDelay
PARENT_DATA_SET            find out the GM identity
TIME_PROPERTIES_DATA_SET   find out whether time is globally traceable
PORT_DATA_SET              knowing the portState can be useful, SLAVE and MASTER

You can make a really simple monitoring application using 'watch'
together with 'pmc'.

Cheers,
Richard
