Hi Guys,

My glances failed to start. When I type "glances", nothing happens. BUT when I type the first Ctrl+C command, the glances open in my terminal.

The keys ESC ou "q" haven't any effect.

If I type Ctrl+c for the second time, glances screen dont close, but glances screen is refreshed.

If I want to close glances screen, I need to press Ctrl+c twice quickly.

The debug log shows error in docker. But FreeBSD does not use docker.

Do you have an idea?

Environment:

OS: FreeBSD 13.1 p1

@devnull-hub-lab can you please run Glances in debug mode (-d) and paste/bin us the log file ?

Any other FreeBSD users with the same behavor ?

Aug 14 '22 08:08 nicolargo

@nicolargo , thanks for your reply.

When I run $ glance -d, in my terminal, nothing happens. (The same occurs without -d). I wait 3 minutes, and nothing: glance

But debug log is generated: https://pastebin.com/SyDRgjdT

When I hit Ctrl+c, glance started on my terminal. Debug log is generated: https://pastebin.com/tBQ2Lu6w

If I hit Ctrl+c again, glances isn't stopped, but refreshed. Debug log: https://pastebin.com/PfhwNkS3

Hi @nicolargo

Some news! I trace system calls during glance execution.

The last system call was: __sysctl("hw.ncpu",2,0x8210b4884,0x8210b4878,0x0,0) = 0 (0x0) __sysctlbyname("dev.cpu.0.temperature",21,0x8210b4a6c,0x8210b4a58,0x0,0) ERR#2 'No such file or directory' __sysctlbyname("dev.cpu.1.temperature",21,0x8210b4a6c,0x8210b4a58,0x0,0) ERR#2 'No such file or directory'

I thought it was a problem with the temperature sensors. So, I disabled sensors plugin:

$ glances --disable-plugin sensors

And Glances runs perfectly fine! :)

The sensors are the cause of the problems. But why? Tomorrow I will do more tests.

Aug 15 '22 23:08 devnull-hub-lab

@nicolargo

I found it. It is related to FreeBSD blackhole. But I cant identify relation between blackhole and sensors. My blackhole settings: net.inet.tcp.blackhole=2 net.inet.udp.blackhole=1

I found other issue (#1202) in 2017, with the same problem, possible related to PSUtil. Maybe can you insert another workaround, like commit 6300af0 ?

What is the best option?

Aug 16 '22 02:08 devnull-hub-lab

@devnull-hub-lab as a workaround, ou can disable the sensor plugin with the --disable-plugins sensors option.

Sep 11 '22 15:09 nicolargo

Hey guys! I have the same issue I've been fighting already a long time. FreeBSD 12.3 I also have following in my sysctl:

net.inet.tcp.blackhole=2
net.inet.udp.blackhole=1

I can confirm glances --disable-plugin sensors indeed fixes the issue.

@nicolargo probably it's good to mention this behavior somewhere in wiki, so people aware what's going on

Thanks guys!
