Can We Find Out Historically What Causes Cpu Load
May 8, 2007
I have a P4 2.4G dedicated which is very lightly loaded. I use the loadavg app from www.labradordata.ca to monitor historical cpu and ram usage. 5-minute cpu load averages don't go beyond 0.5 and the mean is more like 0.05 almost every day.
However just yesterday I discovered the cpu load went up to 38.0 at midnight for a couple of minutes. RAM usage looked normal. This is the 1st time ever that it has happened, and hasn't happened again since. Load has also returned to normal.
I've looked at the logs and from my limited experience, have not been able to find out what caused the spike. Is it possible to find out from the logs? Is there any (other) way to find out what caused the spike or we just can't?

My Server Is down nearly every day in the last three days
I think one of my clients is sending emails from his forum to his members.
How can I know who is he, And most important can I stop him from emailing his members?
Also,
How can I find out which account is making the biggest load on MySQL?

how can i do a search for all files (probs using regex) of files consisting purely of numbers?
for e.g. find:
53243.php
24353.php
24098.php
(always have 5 numbers).
seems one of my accounts has had some script run which generated a bunch of these in various subfolders, and the php file basically does a callback to www3.rssnews.ws and www3.xmldata.info, which seem to be some sort of spyware servers.

I've been having trouble with my VPS for a while now. In the QoS alerts page in Virtuozzo it seems to be a problem with numtcpsock and tcprcvbuf, mainly numtcpsock.
Copy these into the browser:
i18.photobucket.com/albums/b106/gnatfish/qosnumtcpsock2.jpg
And when i run cat /proc/user_beancounters:
i18.photobucket.com/albums/b106/gnatfish/beancounters2.jpg
This line is particularly scary:
numtcpsock 164 164 166 166 7321
What do i need to do, to get the website running again? It's only one site on the vps a proxy. So i thought a vps would be able to handle one proxy.

Anyone know of some good server load testers ( commercial )?
Im not looking for application based load testing, I need real web server load testing... need to see how much traffic this one site can take before it cries.

I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?

I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts

I can't seem to figure out why this is not working. I want to cd into a directory and only compress certain files. However, what I end up with is a file called ..tgz (I am not sure why it is adding that other dot).
Here is the command line:
find . -mmin +1 -exec tar czf {}.tgz {} ;

Someone posted some code similar to below, I made modifications or two after trying to detect PHP "nobody" users, after dumping a few printenv I found PHP exports PWD when calling an external program such sendmail. Basically the PWD will show the user directory that is coming from, which is enough to detect who is sending SPAM even as nobody! It's not 100% secure in that they could wipe /var/log/formmail but I don't imagine any spam will notice the logger, they presume any cPanel server (or other CP for that matter) is the same.
mv /usr/sbin/sendmail /usr/sbin/sendmail2
pico /usr/bin/sendmail (paste the below code into it)
chmod +x /usr/bin/sendmail
echo > /var/log/formmail
chmod 777 /var/log/formail
#!/usr/local/bin/perl
# use strict;
use Env;
my $date = `date`;
chomp $date;
open (INFO, ">>/var/log/formmail.log") || die "Failed to open file ::$!";
my $uid = $>;
my @info = getpwuid($uid);
if($REMOTE_ADDR) {
print INFO "$date - $REMOTE_ADDR ran $SCRIPT_NAME at $SERVER_NAME";
}
else {
print INFO "$date - $PWD - @info";
}
my $mailprog = '/usr/sbin/sendmail.real';
foreach (@ARGV) {
$arg="$arg" . " $_";
}
open (MAIL,"|$mailprog $arg") || die "cannot open $mailprog: $!";
while (<STDIN> ) {
print MAIL;
}
close (INFO);
close (MAIL);

I tried searching for it on google but couldn't find any server company offering VPS using Litespeed instead of Apache. Yes, I know that Apache could be optimized, but would like to try a VPS or dedicated server with Litespeed, just for testing and learning to use and troubleshoot Litespeed. Does anybody here know of a supplier? I would need less than 10 gigs, 250+ Ram as well as cPanel.

Here's my situation:
I run a site that does a lot of transfers AND uses a lot of CPU resources. I think I would like to get two different hosting plans to deal with these different patterns of usage, but where can I find a good host offering lots of bandwidth that is content to have it actually used? I've been with DreamHost for a while but they don't allow "data archiving" or whatever (and I have arguments against their claims but it's neither here nor there). So, really, where the heck can a guy find a good host offering plenty of space and bandwidth? Keep in mind I need pretty much no CPU power with such a plan; the web server can be stone cold stupid for all I care, as I can just get a VPS to run the CPU-intensive part of my site!

I was wondering how you guys go about finding a host?
Where do you do your research?
What forums do you use?
What else do you do in your process before finding a web host?
Do you subscribe to newsletters or web host magazines?

Weve got a server where the /var is setup at 7gb, which is now %100 full.
Weve deleted the common logs we always notice, but thats only gotten us down to %94.
Anyone have any ideas what we should be cleaning or a good script that might help?
seems 5.5gb of data is in /lib
What is safe to delete from /lib and why is it taking up so much space?

Assuming that one was to get a local office in a town, how would someone find building or area that had a high availbility of fiber nearby, but was not a datacenter? Are their fiber maps for each big city? Does anyone have fiber maps for Houston, Texas? I would be interested in seeing these maps if possible.

Just got alerted that my server is being used to send spam. Here is the information the datacenter gave me:
[information .....]
NOTE: I changed the real domain name and IP only.
Is there an expert who can help me decipher this? How do I find the culprit? My provider is threatening to shut me down and sink all my clients with the ship!
I am running the latest WHM and cpanel server, fyi.

I have a web blog that shows promise of growing pretty big soon! This is a vbulletin whith chatbox and arcade games. The forum is for gamers and game modification talk. I want to keep my features such as in forum mp3 player for streaming music. I host no files everything is linked from outside sources. Even photos are linked from photo hosts. I forsee about 20-30 members on at all time browsing and chatting in chatbox. Playing in the online arcade!
I have no idea how much bandwidth all this will use up. I do know that 20-40 gig of space should be quite enough but as always I want all I can get. As far as bandwidth I have no idea what all those features will eat up.
I have looked at fatcow.com and talked to them they said their unlimited is this 300gig space 3000 gig bandwidth and they do not keep up with msql databases. I looked on BBB and they have an A+ record if compared to hostgator they have unsatifatory! The only problem is they are yearly contract only. I do not trust this! I also have to let them re-bill me at end of year and this gives them access to my account. The payment options are check,paybal, or credit.

how to find out one provider if it is an overseller.
Disk storage size
Bandwidth
CPU/Memory
For CPU/Memory it is hard to say how to check, but we can check the allowed Disk storage size and Bandwidth.
The marketing price can be presumed $0.1/1GB for Bandwidth, and $1/1GB for Disk storage size.
If the assumed marking price is correct, we can use this standard to check one provider if it is overseller.
