FreeBSD 11.2 - updating temp for Thermal zone on VM

[daniejstriata]

The FreeBSD server I get the errors below on is a VM, so thermal issues should not be a problem.

• gotop version (gotop -V): 3.5.2
• The output of uname -a: FreeBSD grbl-ffpf.global.test.lan 11.3-RELEASE-p7 FreeBSD 11.3-RELEASE-p7 #0: Tue Mar 17 08:32:23 UTC 2020 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
• Terminal emulator (e.g. iTerm or gnome terminal): GNOME Terminal
• Any relevenat hardware info:
• tmux version if using tmux: not installed

There are a number of FreeBSD issues cropping up. I'm investigating these this weekend. In particular, sensors are causing issues, as reported in cjbassi#190 . There's also a very old, inherited sensor issue #14.

Replicated.

FreeBSD VMs (e.g., QEMU, etc) don't expose thermals, so the log error message is correct: there are no thermal sensors. This can be confirmed by running this command on your VM:

sysctl -a | grep temperature

The sensors gotop is looking for on FreeBSD include dev.cpu.0.temperature, so you can also verify that your VM does not expose this with:

sysctl -a | grep dev.cpu.0

If you do find thermal sensors on a VM, please reply back with a list of them.

Despite the error being valid, it was annoying to have it in the logs, so I've committed changes to make gotop a bit smarter about testing for, reporting about, and limiting repeated logging about missing sensors in FreeBSD VMs.

@daniejstriata are you able to confirm this fix?
