hi,

yesterday i checked the cpu usage in reporting, its overload, i try, shutdown reboot, disable all the plugins, but still overload.

View attachment 1472

probably the cpu is overheating too, but i can't find one way for view.

what can be? how do i fix?

The attachment doesn't work.

Can you get into the console or GUI shell?

If so then type the following and look for the temp

Code:
sysctl -a | grep cpu


Also if you could do a better job of explaining all the indications you are having it would help.

thanks for helping..

i cant see the temps with this code, only basics informations of cpu.

started, when i watched a movie by CIFS, the movie lag.
i see the reporting and notes that value of cpu usage, because other times when i see the reporting, his match with usage in "display system processes"

EDIT:
i take another picture..
FNAS.jpg

now you can see the diference between normal and overload.

Try this one...
Code:
sysctl -a |egrep -E "cpu\.[0-9]+\.temp"


You are not very clear in describing your problem so I understand it. Assume I don't know what you are talking about and be very descriptive.

Other things which can cause a lag issue is if your hard drive is too full.

Hi, I'm a really noob user, but today reading the User Guide , i have found some explanations that maybe cause your problem. You coment that something related to a movie in a CIFS directory.

In the user guide, we can read things like this "If you will be using CIFS, use a fast CPU" or "Windows (CIFS) Shares: the Common Internet File System (CIFS) type of share is accessible by Windows, Mac OS X, Linux, and BSD computers, but it is slower than an NFS share due to the single-threaded design of Samba. It provides more configuration options than NFS and is a good choice on a network containing only Windows systems. However, it is a poor choice if the CPU on the FreeNAS® system is limited; if your CPU is maxed out, you need to upgrade the CPU or consider another type of share."

Maybe i'm wrong :|

ok, i agree with this, but is not this case.

why i use a several times, with movie full-hd, the problem wasnt a lag in the movie, was a overload, right now the cpu usage is in 60%, and i turn off all the services.

in this picture you can see the normal and the overload (begin yesterday)

A few seconds at 100% is NOT "overload". You do realize that CPUs are designed such that they should be able to run at 100% loading forever without the loading shortening their lifespan, right? If you are having heat issues the problem is with inadequate cooling.

If you sat at 100% loading for 99% of the day, THEN I might say you need a faster CPU. I've seen CPUs that, due to inadequate cooling, run at 160F 24x7. There is no fixing it(long story, but it was entirely self inflicted) and the whole intention was to run it to failure. The system came online in Feb 2009 and it is STILL running and hasn't been taken offline at all.

You had very short uptimes from the picture. Is it no surprise that loading will be very high for the first few mins the system boots up? It takes time to make sure everything is okay and begin to cache stuff to increase efficiency along with all of the background activities.

If your picture showed that for days on end the CPU was at 100% usage, then my recommendation is that you need a more powerful CPU.

But to be honest, this thread is almost a joke. There is no evidence by the OP that the CPU is "overloaded". Even a scrub can heavily load a CPU for hours(or days depending on the amount of data). My CPU sits at 100% usage for about 9.5 hours when I scrub my home server. I don't worry about it at all. If you have a temperature problem, then this is the wrong forum to solve your problem. You need more fans, a better CPU heatsink, or better heatsink compound.

in the graph are not just seconds are hours, see that it is selected by weekly. when I referred to "overload", not when the cpu is working above the maximum but, well above the normal. the cpu is a celeron D 3.06.
Good news everyone, back to normal, first I enabled services and then turned off the machine when religuei, returned a while later with processing high but normalized. following image, thanks to everyone who tried to help.

Those graphs show your CPU running normally and you had the system turned off for most of the day before each event. What happens if you just let the system run overnight, maybe it's running a scrub because you turned it off wrong and it's trying to fix the drives? Why you think you have an Overload condition is beyond be. I was thinking you had something actually stating the word "Overload" so I wanted to see the screen shot. I've seen my CPU up to 150% before (dual core so 100% for each core).

I would help you further but there seems to be a language barrier here, you don't understand the questions and are not conveying the problem very well. None of us are mind readers and you need to list out your system details including how the hard drives are configured, you did even mention which version of FreeNAS you were running. When you notice the CPU is running near the 100% mark, click on the "Display System Processes" to see what is running and it might help out.

I'm not trying to blow you off but no one can really help you if we don't have some basic knowledge of what you system looks like. For all we know you have 2GB RAM and a single hard drive, maybe you're running this in a virtual machine? I don't know so it's hard to help.

My advice, turn it on, leave it alone and let it do what it needs to do. Can you tell if the hard drives are being heavily accessed? That would be a good clue for us to help you out.

Cheers

now, he come back to normal. when i have the "problem", i disable all the services, and the usage of cpu still high, and when i see in "Display System Processes" have one or other using 1 % , 2 % only this. but now its ok.. thanks
