Load Averages
May 21, 2009I understand how the load averages are calculated and what the numbers represent but what would be considered a high load average and at what point would the server need upgraded?

Load Averages
Jun 15, 2009That would be impossible as the LOAD as given in linux/unix has nothing to do with the cpu load of a server but the total of processes queued (waiting for their turn). If their main node has such a high queue count it should be fairly easy to see for them which process is causing that. No idea why some hosts keep sending their customers to fairytale land every time when it comes to linux load information. Anyways; Exim with that many processes doesnt sound to good either.
As for one VPS bringing down the main node; this is really not that strange as you keep in concideration that a VPS is still a node with many shared customers. Where some things can be regulated, like cpu cycles and memory, but if your node goes completely balistic on its disk IO it will bring a VPS-main node to its knees.
Server Load Averages
Mar 26, 2009I've never fully understood load averages, I've read articles about what it means but I still don't fully grasp what they are and their meaning.
For example, if I'm to understand correctly, if the amount of processors is greater than the load, then the server is not behind on processing. For example, if a server has a load average of 3.4 and is quad core, this would mean it's not 'under strain', correct?
I have a dedicated server, 2 3GHZ CPUs and the following load averages:
Quote:
Load Averages3.25 3.61 3.69
Does this equate to my server being strained, or handling fine?
Load Averages In Linux Are Confusing
Jan 26, 2008the Load averages in Linux I tend to find confusing, I've read that its the system load averaged over 1, 5 and 15 minutes but beyond that I never seem to find a clear cut answer as to what is considered a normal system load.
For instance I have a p4 D 3Ghz with 2gb ram and a single 250gb SATA HDD
the 15min average sits around 0.85 during the busiest time Is that good bad or indifferent?
The server hosts my sites and that of a few friends.
[url]shows what MRTG is outputting about the load averages.
It also says the CPU is 520% although I believe it multiplies it by 10? (i changed the title to say that) so its around 52%
Apache/High Load Averages
Sep 10, 2008been checking out this site for a while and finally decided to register because I have a problem. Also hope this is the correct forum for this topic, sorry if it isn't.
So I have a problem with Apache. One of the sites that I run/host has a moderately large vBulletin board, and Apache just seems to eat up the CPU. Load averages have shot up between 20-30 and I've seen it as high as 80. Apache and MySQL are optimized already, I'm using suPHP for security because there are other sites on this box.
The funny thing about this is that it only started happening about a week ago. After checking for rootkits and all that garbage, I reinstalled the OS just to be on the safe side. Everything comes back clean still. I also got fed up and hired Platinum Server Management for a month, to see if they could find a solution (and I've been interested in reselling their services, but that's not relevant). So far the only thing they can come up with is disable suPHP, which isn't an option. I do realize that suPHP is ~20-25 times slower than mod_php, but what totally baffles me is that it worked beforehand and started going all crazy like this. I did try running the site using an dso configuration, the load did drop, but nothing to be proud of.
This site, and the server overall hasn't had any increase in load, I've held off putting new accounts on it until I get this fixed.
In the meantime, I have said forums running on lighttpd, which lowered the load. (Also writing a tutorial on having lighty work with cPanel)
WHM Load Averages Display And MySQL Stats
Feb 17, 2008I have one server where cPanel WHM displays the load averages at the top right, but another server where it doesn't. How do I enable this? And what do the three different numbers shown (e.g. "Load Averages: 0.99 1.17 1.43") stand for?
way to get MySQL stats such as queries per day and things like that?
Website Extremely Slow To Load/doesn't Load (numtcpsock)
Dec 20, 2007I'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.
Load Testing :: Server Load Testers ( Commercial )?
May 6, 2008Anyone 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.
Some Sites Load Slow, Some Sites Load Fine, Server Load Is Fine
Aug 12, 2008I'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?
How To Check Load Via Ssh And Check Files Causing Load
Jul 1, 2009I 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
VPS Load
Mar 16, 2009I just got a futurehosting VPS recently and something is puzzling me. Is it normal that an idle CPanel virtuozzo VPS that has no sites on it should display "top" loads of between 1 and 4 regularly? I've been watching the load for a bit now and it keeps jumping between 0-4. When it goes 1 or above, the WHM panel becomes really slow, timing out... They seem to use a beast 8 core machine, so it would take some activity to cause even a 1 load..
I do not have much knowledge about VPS hosting, on a dedicated I would expect the loads to stay 0-0.2 at this point... Is the 1-4 load showing the result of heavy usage by other VPS users on the node? There is absolutely nothing that could cause a load in my vps as far as I see... Is this perfectly normal on any VPS?
CPU Load: 259.33/166.35/119.93
Jul 14, 2009You think this is funny? Not at all.
I'm on LON03 server and I recive yesterday from Future Hosting this advise about hight load.
I got then 1 month ago, and the solution was *JUST* to remove a phpBB website with 80+ users.
I do not believe that the VPS could get this kind of loads.
Funny is that the VPS was "monitored" by them at the same time. They say the load spikes out for times to times in a matter of seconds.
This load is taken from the Parallels Infrastructure Panel or even the Node Panel, not from the VSP itself. Even when I'm logged in.
I've been a client for 6 month, and 2 of the last 3 constantly getting CPU hight usage. Strange is, that I come from a 512mb/25gb PowerVPS server to a 1GB/30GB server, with the *SAME* sites.
Anyway, the prupose of this topic is to:
- check if anyone had this problem (problem is: beeing sure that this load is IMPOSSIBLE to be created from yout service)
- recommend a decent VPS provider besides Future Hosting and PowerVPS.

what is the acceptable average load?
cos for mine, i see most the time is less than 1, but at times, for no particular reason that i know of, it can go up to between 5~10
I/O Load
Aug 29, 2007Due to high IO load server is going crash once a day.
I have optimized the MySQL, Upgraded the kernel but still it's same. The SWAP seems normal.
Now probably it is due to high traffic of http or emails. How should I diagnose and fix it? I am in big trouble.

Load Balancing
Jun 21, 2007I want to have a fail over for my server. I was told that load balancing is the way to go.
Could anyone give me some instructions of what I would require. My primary server contains Cpanel.
Load Balancing ...
Apr 8, 2008the loads on my server is VERY HIGH and it needs to be upgraded fast.
I really have no clue as what to do... and i do not know any expert other than you people here - to help me out and put me on the right track.
i was thinking of
1) Getting a server with better CPU and more RAM
2) Load Balancing
However I know nothing of load balancing (other than how to spell it correctly )
1) Which of the above two options should i choose?
2) what are the extra costs in load balancing?
3) what should i know about load balancing before deciding?
4) How does load balancing work? I know there are two server - like one for database and one as webserver... but how does this work together?
5) what config should i be looking at in the two servers?
I'll stop here else i can go on and on and on...
I am giving the details of my server and service below, in case you guys need it.
Load Balancing / HA
Sep 18, 2007We host a large number of small websites and are looking for high-availability and the ability to do maintenance on our application servers, so I'm looking for a load balancing solution. At this point, I'm considering Zeus ZXTM LB software, the Coyote Point e350si, and potentially an F5 1500 LTM.
The F5 solution is a total budget buster, and the Coyote Point UI is rough around the edges, but I've used them and they are reliable. Zeus looks like a winner with a great UI, but I haven't heard much about their reliability.
Bandwidth requirements are low at this point, so this is mostly about reliability and ease of configuration of a moderately complex set of services.
Any opinions on these vendors, or alternates I should consider?
CPU Load Balancing
Oct 23, 2007I run a GSP (Game Server Provider) and i just baught 2 new octi xeon servers(Intel 5320)
i am having a problem with the load balancing, it dosen't balance de cpu usage on all cores but only on one, and it gets at about 80-85% and 3%CPU usage on the other one.
Load Balancing?
Jun 18, 2007I was currious as to some suggestions you guys may have for setting up a load balanced website...
I would preffer it to be software based and free as I am just using this for some testing purposes.
Load Balancing Over WAN?
Jul 11, 2008I'm looking at load balancing a group of servers located at different data centers.
How feasible is this? Which options/solutions should I take a look at?
I would like to route using some sort of IP tunneling or similar so that the user doesn't see ww1.domain.com etc.
I will be distributing the load of the static/dynamic web pages, no database clustering.
I would prefer something a bit more intuitive than round robin. Perhaps directing incoming traffic based on existing server load etc.
Most of the load balancing solutions I've looked at assume all your servers are on the same local network.
Load Balancers?
Aug 19, 2007I'm just curious, how many around here use load balancers in front of their webservers, and what kind of traffic do you push with them? (What kind of load balancer as well) Any other specifics would be nice as well.
Also, do you have failover for your load bal?
Load Balancers?
Oct 19, 2007Hi. Can you please tell me how hardware load balancers work? I mean. What would i have to do to load a balance a site of mine?
Also what type of price range would i be looking at and what to look out for.
Load Balancers
Oct 22, 2006I'm really curious what makes the high end load balancer better than the low end ones.

High VPS Load
Jun 24, 2009My VPS holds about 80 domains and low-use accounts.
Every night, from around 1.30am, the load suddenly skyrockets and will usually be around 5 to 10 for a few hours. Occasionally it'll spike to 30+ for a few minutes.
I had some antispam software running, and a couple of other packages (mail queues, mail manage etc), so I disabled all of that and removed all the crontab entries etc.
It's not really made any difference.
I can see the load stats going back 8 hours, as part of the ASSP spam package (I've just left the ASSP server load cron running just so I can continue monitoring it!)
Can the apparent load on my VPS be caused by other VPS's on the same node?? So in reality, my load is fine but is being affected by other people's VPS's?
I hope that makes sense. I'm 99% sure that my VPS is 'clean' (in so far as cron entries)
I'm asking the question because I took a second VPS on the same node and that one too has high loads overnight when there's nothing running on it (ie, no add-on software, no Cpanel accounts added)
