Hello,

does anyone know how to read the temperature of an Ubuntu device? Finding SNMP OIDs is almost impossible.
Specifically, it's about the Unifi Dream Machine. The temperature is to be read out here. SNMP is active and working.
Are there any other ways to generally determine the temperature under Linux using the KS Hostmon?

greetings

HDD temperature? motherboard? CPU?
Does your system supports some protocol like IPMI or HP iLO? I assume not..
May be lm-sensors package may help?

Hi Alex,

sorry for the vague statement,

I meant the system temperature of the UDM on which an Ubuntu is running as the operating system.



I test it once with net SNMP.
Thank you

Hi Alex,
I still have a question while monitoring the RAM usage, I get strange values as an answer.
3.7 GB of 3.98 GB are currently occupied.
With the OID "Total RAM Free: .1.3.6.1.4.1.2021.4.11.0" I get "116636". I think that's kilobytes. That would be 130 MB if converted by dividing 1024. But it should be 280 MB.
What should be set here in the "Tune up reply?"


greetings

Yes, it should be KB units. Counter usually returns the total amount of memory free or available for use on the host; value typically covers both real memory and swap space.
Results can be different - there are many versions of UNIX and Linux and some versions of net-snmp-libs works differently.

I would suggest to use Memory test instead of SNMP Get test

Hi Alex,

Many Thanks!! It can be so easy using the memory check!
Didn't even think of it ...

The return is now worth 13%. Should actually be 7% according to the ad. But it still works for us so far

Thank you and have a nice day

greetings
