The file was what?

This was a mistake in my mail mail. I had written about cpuinfo_cur_freq and deleted (not complete bacause my tablet has not showed it) this part after i have readed the mail again and found the missing "profile0" in Matthias path.

I had added the infos to the bug and wait for comments before i change it again...

I think this need more investigation.

This was triggered by https://git.ipfire.org/?p=ipfire-2.x.git;a=commitdiff;h=37458540bf727df09989 c10d640ad13c1a989029

I thought some cpu graphs on my "Duo Box" could be helpful and installed 'cpufrequtils'.

But after adding the above commit to '/etc/init.d/collectd' and restarting 'collectd' => no graphs appeared.

Reason: The needed directory '/sys/devices/system/cpu/cpufreq/policy0/' doesn't exist on my machine, so the 'LoadPlugin' was always commented and deactivated.

Instead there are '/sys/devices/system/cpu/cpu0' and '/sys/devices/system/cpu/cpu1'.

So I tested this the hard way.

After commenting the if-statement, everything is working, CPU graphs appear and show reasonable values:

... # Enable cpufreq plugin if cpufreq found #if [ ! -e /sys/devices/system/cpu/cpufreq/policy0/*_cur_freq ]; then # sed -i -e "s|^LoadPlugin cpufreq|#LoadPlugin cpufreq|g" /etc/collectd.conf #else sed -i -e "s|^#LoadPlugin cpufreq|LoadPlugin cpufreq|g" /etc/collectd.conf #fi ...

Changed this to:

... if [ ! -e /sys/devices/system/cpu/cpu0/cpufreq/*_cur_freq ]; then ..

But this gave me an error:

/etc/init.d/collectd: line 95: [: /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq: binary operator expected

I changed the line to:

... if [ ! -e /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq ]; then ...

And now it is running as expected.

Would this be ok for other machines? Bug or feature - can anyone confirm?

Best, Matthias

P.S.: I didn't forget the Telko - I was still at work. Too bad...
