Core 199 - collectd - cpufreq-plugin floods syslog

Core 199 - collectd - cpufreq-plugin floods syslog

[Matthias Fischer]

Hi,

just in case that this happens to somebody else:

Some days ago I made a fresh install of Core 199 with a new machine and
rather old cpu (i7-2700). Runs fine and has more power than the old Duo
box. Fits my needs.

But I couldn't disable HT in BIOS - 'htop' finds eight CPUs. Should be
no problem - but it is.

The problem came with the 'cpufreq'-plugin, my logs were flooded with
warnings:
"cpufreq plugin: Reading
"/sys/devices/system/cpu/cpu4[5,6,7]/cpufreq/scaling_cur_freq" failed."

Because of the deactivation, 'scaling_cur_freq' was empty, there were
complains about CPU 4-7 (the deactivated ones) and in no time my log was
filled with about 10000 'collectd'-entries.

My solution was to change the loglevel of the 'Plugin syslog' in
'collectd.conf' from 'info' to 'err'.

Can anyone confirm this behaviour?

Best
Matthias

Matthias,

I always get your emails to the list, followed by a second message that your emails aren’t appearing on the list. I’m guessing the issue is that you are not receiving a copy of your own e-mails?

Either way, it always seems to be working properly to me.

2cd try:
For reasons unknown to me, my Mails no longer appear on the list, even
though I can send them there without any errors.

Therefore: next attempt - plus CC to MT [Hi Michael... ;-) ]
