Meinberg LANTIME Devices: Non-GPS Refclock State (NG MIB)
This check monitors the refclock state of Meinberg LANTIME clocks supporting
the new MBG-LANTIME-NG-MIB. It is only applied to non-gps (i.e. radio
frequency) refclocks, since the gps refclocks have their own subcheck.
The check handles the reported state of the refclock and provides additional information
about its state, like the field strength and the corellation.
When the refclock state is "not available" CRIT is raised and a WARN state is issued
if the refclock state is "not synchronized".
The index number of the refclock.
One service is created for each non-gps refclock.
