High Server Load - How To Check From Logs

View 14 Replies View RelatedHigh Server Load / High Swap / Lots Of Httpd
Feb 20, 2008I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)

Server High Load/high Mysql Usage
Jul 2, 2009I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
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
How To Check Which Mysql Databases Cause Server Load
Jul 30, 2007How can i check (using SSH) which databases/users cause server load to mysql ?
I've tried "mysqladmin proc stat" but it shows just the current. How can i get stats of the last 24 hours for example ?
I've also seen slow connections stats. What is the command to check more detailed report of the slow connections; which databases caused it etc', in the last 24 hours for example as well.

View 4 Replies View RelatedToo High Server Load, How To Handle
May 4, 2008if upgrading to that new server that I'll mention will probably solve my problems. Whatever help you can provide would be greatly appreciated. Below are the details:
In the GMT evenings and nights my current server gets so loaded that every page load takes 10 - 30 seconds. Even the pure html pages will be so slow to load. It seems that after a certain treshold it just suddenly becomes that much slower. Not much middleground there. I have high MaxClients and ServerLimit values now and the error log doesn't say that they are exceeded anymore but that didn't help enough.
I have a high traffic website that is using latest version of apache (2.2.x) with the prefork MPM and apache is optimized, PHP 5.2.5 and APC 3.0.15.
I get 160,000 - 210,000 pageloads per day. 32,000 - 45,000 visits per day.
Most of its pages are PHP but shouldn't be too CPU or databes intensive. Mysql isn't used and I mostly used sharedmem (php's shm functions) for databases. 2 semaphores are quite heavily used but that can't explain how a few more users would make the server serve pages so much slower.
Swap usage is practically 0 and CPU user % usage is like 1 - 2 % and CPU system % is also about the same even during peak times. However the Average Load or whatever that "top" reports is 6 - 9.
My current server scecs: 1 GB Ram, Pentium D 3 ghz, CentOS 5 32bit fully updated.
I load all pictures and even the stylesheet from a secondary server by using href="$secondaryserverIP..." in the html code, so the main server practically just serves the pages.
My new server will have apache with the worker MPM and latest versions of every software. Also its specs are: 2 GB of RAM, Intel Dual Core Xeon 2.40GHz, CentOS 5.1 32bit fully updated.
I have a sophisticated netstat based ddos script that is an improved version of DDoS Deflate and while some of these slowdowns seem to have been caused by attacks that it then was able to defend me from, most of them are not. I am even protected from users who constantly have 7+ connections to my site and if someone has a way too high number of connections, the script won't even check if it constantly has it and the script just bans that user outright. It probably is banning a bunch of innocent proxy users too but that is a small price to pay.

MySQL High Server Load
Dec 18, 2008MySQL the last few days seems to be constantly the most demanding process in top, which it never was before.

High Server Load And Slow Performance
Mar 11, 2009I am currently hosting my website on one server with the specs:
2.8ghz Dual Quad-Core processor + 8 gigs of ram + two 500 hard drives with a 50 mbps unmetered bandwidth package.
My current problem lies in high server loads and very slow server performance throughout the day.
I am considering migrating over to The Planet onto server with the specs:
3.0ghz Dual Quad-Core + 18 gigs of ram + two 50gb hard drives with 2TB of monthly bandwidth transfer.
In an attempt to have great bandwidth pricing and server performance, I plan on downgrading my current server with my current host to a lowe-end server and keeping it only to host my VIDEO and MUSIC files with the 50mbps unmetered package. The Planet will then host my database and all other web related files on their new server.
Is this a good idea as an attempt to save money in bandwidth costs and eliminating my server lag issues?
I was offered a setup of a separate web and database server at my current host but from what I have read, no one touches the performance and reliability The Planet has to offer.

High Server Load - Httpd Processes
Mar 23, 2008a topic long time ago that my server load is frequently high.
I'm talking about something like this
Server Load 158.86
Memory Used 28.2 %
Swap Used 99.57 %
[url]
The only way to solve this problem is to identify the load earlier and kill all httpd process. What I did was
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
On previous thread, I tried to update mysql & php and it works,
Right now again I am experiencing high server load again...
I'm very sure it's caused by httpd but I am still unable to find out the real cause of the problem and which account user is the culprit for causing this high load.
Can someone assist me by telling me where/how to begin with?
Incoming Spam & High Server Load
Dec 17, 2007I'm having problems with incoming spam on my dedicated server the load average of the server is around 80 or 100.2 I know it's incoming spam because when I check the exim process I see a lot of ips from russia, germany, taiwan then I block that ips with the /etc/apf/apf -d ip command and then the load of the server drops down to 7 or less, so the cuestion is how can I detect and block the spammers ips automatically on the server? I have spam assassin running and blocks the spam emails right, the real problem is the high load generated for spamd application and all the incoming connections of the spammers ips on the server.
Server specifications:
Cent OS 4
Control panel: directadmin
Dual-Core AMD Opteron(tm) Processor 2214 HE
1GB RAM
Exim 4.68
Apache 1.3.39
MySQL 5.0.37
vm-Pop3d 1.1.7f-DA-2
Which Command To See What Is Causing High Server Load.
May 18, 2007Which command do we type to see what is causing a high server load?
I've restarted the VPS numerous of times, and I wish to found out the problem
High Load On Apache/PHP Server - What Can I Twiddle
Sep 2, 2007I deal with a server that gets positivey slammed once a week for a few months per year. I'd tell you how many hits we got tonight, but I'm still waiting for AWSTATS to chew through the 2gb access_log file...
Tonight, I made some changes that SEEM to work, but I"mn not sure what the long-term effects could be. If we have any apache experts on the forums, I'd really like to bend your ear for a few to see what you know.
Obviously, with PHP, we're limited to prefork MPM.
First of all, I dropped Timeout from 300 to 120. That should be MORE than enough time to know that we've timed out. Then I dropped KeepAliveTimeout to 5 from 15.
Here's the radical one. Watching the process list and the load, it seemed that load spiked when the processes hit their end of useful life and respawned. Duh. This was happening every four seconds at the load we were under. MaxRequestsPerChild was set to 10,000. I upped this to 80,000 over a period of hours that we were under the load. I didn't see any significant memory leakage, but it's the change I'm worried about the most. I've seen Apache do some bad things when people allow this to go unlimited, and had always used the relatively low default as a guide.
Besides not loading a bunch of dynamic modules (also done, I usually do this so I'm not worried about it), what else can I do tuning-wise to keep load down? Please note that caching and load-balancing aren't acceptable solutions; I have one server to work with (for now) and the boss says no to caching because of how frequently our information updates. We also have extensive .htaccess files, so there's no LHTTPD in my future.
