[fr0s7]

Sure, I'll gladly help.

 

[Viktor Jaep]

Sure, I'll gladly help.

Sorry for the delay @fr0s7 ... please download this debug version:

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/RTRMON/develop/rtrmon-debug.sh" -o "/jffs/scripts/rtrmon.sh" && chmod 755 "/jffs/scripts/rtrmon.sh"

Then just run it like normal:

rtrmon -monitor

Wait until the script finishes running when it hits that error, then please copy all the output from your screen and dump it here below, or send me a file, or just PM it to me. I'd really appreciate it!

 

[fr0s7]

Done, attached is the output file.

 

[Viktor Jaep]

Done, attached is the output file.

Thank you! I think it has something to do with your CPU temps... could you please run this and see what you get back?

cat /sys/class/thermal/thermal_zone0/temp | cut -c -2

 

[fr0s7]

cat: can't open '/sys/class/thermal/thermal_zone0/temp': No such file or directory

Got to /sys/class/thermal directory but it's empty, I guess the temps are reported elsewhere?

 

[Viktor Jaep]

cat: can't open '/sys/class/thermal/thermal_zone0/temp': No such file or directory

Got to /sys/class/thermal directory but it's empty, I guess the temps are reported elsewhere?

Could you please give this a try?

cat /proc/dmu/temperature

 

[fr0s7]

cat: can't open '/proc/dmu/temperature': No such file or directory

There's no dmu dir in /proc

 

[Viktor Jaep]

cat: can't open '/proc/dmu/temperature': No such file or directory

There's no dmu dir in /proc

Is there anything under /sys/class/thermal/thermal_zone1?

 

[dave14305]

cat: can't open '/proc/dmu/temperature': No such file or directory

There's no dmu dir in /proc

How about cat /sys/power/bpcm/cpu_temp

 

[fr0s7]

cat: can't open '/sys/class/thermal/thermal_zone1': No such file or directory

cat /sys/power/bpcm/cpu_temp
cpu_temp: 64.758 C

Nailed it.

Hi @fr0s7 ... What is the actual output when you run this command? Does it just show:

64.758

Or is there other info when you run that command? I need specifics please. Please paste all the output from your screen after running that command if you don't mind?

I think what he showed is exactly the one-line output.

Lol almost looks made-up!

OK @fr0s7 ... could you please give this patched version a shot, and see if this no longer produces errors, and gives you the correct temp readings?

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/RTRMON/develop/rtrmon.sh" -o "/jffs/scripts/rtrmon.sh" && chmod 755 "/jffs/scripts/rtrmon.sh"

 

[fr0s7]

Yes, this one works, checked different readings and all seems to match:

That's great news, thank you!

New BETA to test the waters and make sure is looking good... HUGE THANKS to both @ExtremeFiretop and @visortgw for their incredible team work on this! Both of these guys are amazing to work with!

What's new?
v2.2.4b - (Release date TBA)
- PATCH: HUGE HUGE THANKS to both @ExtremeFiretop and @visortgw for their help getting the wired/wireless client page (#7) working again. Apparently something had broken between a firmware release that seemed to be causing some incorrect reporting on this page. Both these guys stepped in, and were able to collaboratively knock it out of the park, and get this page to report things accurately again. RTRMON wouldn't be as awesome as it is without these two incredible gentlemen! Thank you!
- PATCH: Thanks to a CPU temperature issue report from @fr0s7, it was found that the normal methods of finding CPU temp readings were no longer working on the RT-BE92U. @dave14305 came to the rescue, and was able to find the correct file for a temp reading. Thank you both!
- PATCH: Some oversight on my part... after my efforts to optimize my code, I inadvertently left out an optimization that affects vpn/wg connections that are using private IPs, and was causing a 1min delay when RTRMON started up. I got this added back in, and is launching successfully again. Thanks to @visortgw for the report!
- PATCH: Changed the date/time to include the offset alongside the timezone. This is to give more visibility for those who aren't assigned a standard timezone name, and in some cases would fall back to using "GMT". Thanks to @Tarek Yag for reporting this, and for @EmeraldDeer providing a deep dive into the date command options.
- PATCH: Various spacing tweaks to ensure alignment of required data elements. That's right. I blame the OCD.

Significant Screenshots:

TZ offset now being shown. Also, please go check out the fixed wired/wireless network connections on page 7!
