I’ve been running an old version of LibreNMS happily for many years but have decided to retire this server and move on to the latest greatest.
The new one is up and running fine. I started with a couple (2) Mikrotik routers from old system (disabled each on old system). Configured SNMPv3 and polled with the new Librenms install. Devices were detected fine and polling continues fine, except this latest version does not retrieve temperature and voltage data. I don’t really care that voltages are not there but the temps are important to me at least.
I looked into the rrd files for each device on the old server and the on the new server and find there are missing the sensor rrd’s. I would expect that they would be there after initial device discovery but apparently not.
This is old version.

On the old version the RRDtool runs this. (excluding the graph formatting and print)
DEF:sensor=/opt/librenms/rrd/random_name.sn.mynetname.net/sensor-temperature-mikrotik-0.rrd:sensor:AVERAGE DEF:sensor_max=/opt/librenms/rrd/random_name.sn.mynetname.net/sensor-temperature-mikrotik-0.rrd:sensor:MAX DEF:sensor_min=/opt/librenms/rrd/random_name.sn.mynetname.net/sensor-temperature-mikrotik-0.rrd:sensor:MIN CDEF:sensorwarm=sensor_max,48,GT,sensor,UNKN,IF CDEF:sensorcold=sensor_min,20,LT,sensor,UNKN,IF CDEF:sensor_diff=sensor_max,sensor_min,- AREA:sensor_min AREA:sensor_diff#c5c5c5::STACK LINE1.5:sensor#cc0000:'Temperature 0
Is there anything I can do to remedy the missing temperature RRDs?
thanks
