Title: CPU temperature alert
Post by: ddt3 on August 14, 2022, 02:31:22 pm

I have just bought new hardware to run OPNsense on. Because of what I have read on the internet. I woiuld like to keep a close eye on the  CPU temperature  of this mini-pc (https://www.amazon.com/Firewall-Appliance-OPNsense-Untangle-HUNSN/dp/B0B53P9P2Y?th=1).

I can of course have a look at the cpu temp in my OPNSense dashboard or at the graphs in Reporting. But I would rather have some kind of alert when the temperature rises above a certain value.
So therefor I would like to know:

• Can the CPU temperature(s) be retrieved using snmp?
  I did an SNMP walk but found nothing, the OIDs I found using google also did nothing.
• I could also use an alert in monit for CPU temperature
  I did find some description in the monit documentation so I created a script that returns the cpu temperature.and then found an example how to use that in monit.
  

  # set the trigger temperature
  check program CPU-Temp with path "/usr/local/etc/scripts/cputemp.sh"
      if status > 62 then alert

  
  But I can't figure out how to add that to monit using the OPNsense UI.

Thanks!
Feel a bit silly for not finding that but monit is running a  temperature check  now :-)
