my question is , does mikrotik device get temperature information to prtg ??
and if it get to prtg , how it work?
Yes, you can get temperature, voltage, and so on via SNMP.
Just obtain the correct OID with:
[admin@xxxxxx Router] > /system health pr oid
active-fan: .1.3.6.1.4.1.14988.1.1.3.9.0
voltage: .1.3.6.1.4.1.14988.1.1.3.8.0
temperature: .1.3.6.1.4.1.14988.1.1.3.10.0
processor-temperature: .1.3.6.1.4.1.14988.1.1.3.11.0
current: .1.3.6.1.4.1.14988.1.1.3.13.0
fan-speed: .1.3.6.1.4.1.14988.1.1.3.17.0
fan-speed2: .1.3.6.1.4.1.14988.1.1.3.18.0
power-consumption: .1.3.6.1.4.1.14988.1.1.3.12.0
psu1-state: .1.3.6.1.4.1.14988.1.1.3.15.0
psu2-state: .1.3.6.1.4.1.14988.1.1.3.16.0
and put into PRTG custom SNMP sensor.
