Meinberg LANTIME Devices: 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 GPS refclocks. Other
refclocks have their own subcheck.
The check handles the reported state of the refclock and provides additional information
about its state, like the number of satellites.
When the refclock state is "not available" CRIT is raised and a WARN state is issued
if the refclock state is "not synchronized".
If the number of good satellites drops below 3 and the device substate indicates that
a satellite connection is necessary, a CRIT state is raised. If the substate indicates
that no satellite connection is necessary no information about satellites is shown.
Substates that require a satellite connection are "GPS sync", "GPS tracking",
"GPS antenna disconnected", "GPS warm boot", "GPS cold boot",
"GPS antenna short circuit" and "MRS GPS sync".
The index number of the refclock.
One service is created for eachr GPS refclock.
