Wrong Error-Message when Meinberg NTP-Servers changes Stratum Level

When a Meinberg NTP-Server (in our case a Lantime M300 with the latest Release 6.24.028 from April 2021) changes the refernce time and/or stratum status this is recorded as "Hardware changed" in the logfile. Which is misleading.

The attached Screenshot shows a Server "spamming" the logfile with these messages.

The "Hardware change" just means that the reference time when in Stratum 2 mode changes from time to time from .12 to .15 (whoever has the most stable time that the NTP-Daemon chooses). The "Hardware change" to "GPS" just means that the server is back to Stratum 1 mode ...

The Meinberg itself does not record the changes in reference time - but the change in Stratum-level :

2021-04-26 09:22:28 UTC: LANTIME -> NTP Sync To GPS
2021-04-26 09:22:28 UTC: LANTIME -> NTP stratum changed from 2 to 1
2021-04-26 09:15:00 UTC: LANTIME -> CLK1 Sync

It seems that observium does not record the change of the CLK1 status nor the stratum-change but gets this strange information from snmp.

It's maybe a cosmetic bug - but it still might be something you can have a look to.
