what tools are available for Fedora 4 that allow an admin to set limits on how much memory and cpu usage clients can use. I have plesk 8 but I can't seem to find anything related to it in there, and I set up webmin as well,
View 2 RepliesHow can I limit my dedicated server's resources ? For example, one of reseller provider's limits :
Quote:
Resellers may not use more than 2% CPU daily, 3% memory daily, run more than 10 simultaneous processes per user, allow any process to run for longer than 30 seconds CPU time, run any process that consumes more than 20% of available CPU at any time, or run any process that consumes more than 16 MB of memory. Databases are limited to 16 max user connections with a max query time of 8 seconds. Cron jobs must not execute more than once every 15 minutes and will be niced to 15 or greater.
From where or how can I configure these limits?
I just got a new server Dual E5520 with 6GB RAM, SAS 15k rpm raid10. It's running well. However, the memory usage is just around 2.5GB, even when I have more traffic. Here is the kernel info

Any idea that we can put more content into memory?

If I have a two sites that, combined, get about 125,000 page views monthly (that comes out to about 4,000 page views daily). The sites are powered by Wordpress, and it is being used as a CMS, it's not a blog. There are a number of plug-ins in use, on each site, about 10 or so. Each site also has a vBulletin forum in use, although there are rarely more than 10 concurrent connections, if even that many (total of 400 members, only 150 of which are active -- combined stats for both sites).
Currently the PHP memory limit is set to 16M. I'm wondering how high it could or SHOULD go? Granted, I would not want to ask for more than what is available. Would the site speed improve if it was upped to say 128M? Let's pretend that I have a 512MB VPS SLM (no burst). It would have Linux+Apache+Plesk.
Is that enough of a VPS? Would I need to go to 640MB, 768MB, or even 1GB of RAM? Budget is an issue, so "yeah sure, go larger" is not an easy decision. It's also stupid to buy what's not actually needed. Maybe 256MB-384MB would be good enough?
Now then, what if I wanted to use this on a Windows IIS6 system instead? Let's say that I decided to add an ASP.NET wiki or blog to one of the sites. Clearly, that would demand more RAM, and I think Windows itself likes to eat more RAM. The Windows box would also have either Plesk 8.6 or Plesk 9. What's the difference in base RAM use that should be accounted for?
Virtuozzo is desired for either solution, be it Linux or Windows.
My current situation is shared, Windows 2003 Plesk, for these particular sites, and these two specific sites are loading really slow sometimes. Other times I get partial loads, error 500, or pure "unavailable" issues. Other sites, same machine, just fine.
Even the vBulletin forums on the same domains load okay and fast, but the Wordpress sites crawl. It is IIS6, so use of WP-Cache/etc is pretty much impossible. I tried another cache, and it works -- but only for maybe 2 hours at a time, then something happens to it, and the cache quits. It's enabled, but it just stops functioning properly.
My shortlist of the moment includes KickassVPS, FutureHosting, and EuroVPS, for whatever new VPS plan that needs to be gotten. I've been watching the VPS offers threads for the past two weeks. I'm leaning hard to FutureHosting, for this one project, because of the Seattle NOC, since one of the site admins is close geographically, and he always has trouble with the current site's location (other side of the globe, for him).
I'm hoping some of the WHT experts have some good answers for this. I've been researching this for a while, both on WHT and off, but I can't seem to get a clear answer from reading alone.
some web hosting company limit cpu/Ram and if any account do high load it will suspended some time automaticly and unsusprnded after some time auto
View 0 Replies View RelatedI have a server running Apache 2 with php 5 as an apache module. There are 2 PHP scripts that get about 500k hits a day. These scripts have to parse data out of a remote webpage and display it on an image. They used to make loads go up to 40-50, but I have added a cache which only updates every 4 hours. This helped a lot, but loads are still around 10 when the script updates, and it slows down the server. Memory usage is fine.
The server is an AMD Athlon 64 2800+ with 1 gb of ram and an 80GB SATA hard drive.
Here's `top` when the cache had just been cleared.

Idle CPU usage usually goes anywhere from 30%-0%. Is there any way to limit apache from using more than 75% cpu, or any other ways to drop cpu usage?
i have one centos dedicated server and cpanel i will going to apache status is very request link and 2 site are very high in the list and my apache worked very hard and going to down any hours of your seems i must how control it?
View 7 Replies View RelatedI run 10+ sites on my dedicated server.In last 7 days one of them used over 1.7 TB of bandwidth.
I can't suspend that domain because it's mine.
I can't ban the IP of those who use considerable amount of bandwidth because they are a lot.
So i think about software/mod/whatever else that limit bandwidth usage per user(IP) per day! is there any one who has experience about this situation?
I know bluehost.com "sort of" does this. If you use more then x % of the total CPU or memory of the server, then your account will be limited automatically.

why, or when this happened, but all of a sudden the PHP Memory Limit for all of my domains is 64M? I used to have it set to 128. How to change this setting so that all domains have the ability to go to 128M ?
View 5 Replies View RelatedIt seems that a user may get more percentage of memory purchased for real use. I've got a xen VPS which has access to all 8 CPU cores. Guess this is a good thing to be able to burst CPU resources
[xwu@atom ~]$ cat /proc/cpuinfo | grep processor | awk '{a++} END {print a}'
8
But this requires lots of kthread running to be able to access all CPU resources, which in turn consumes quite some memory, a valuable, limited resource on a small VPS instance.
[xwu@atom ~]$ cat /proc/meminfo | grep Mem
MemTotal: 524288 kB
MemFree: 276128 kB
The output above is grathered when almost no other services are running except sshd.
While XEN VPS surely consumes more memory than OVZ VPS, I would suggest the Xen VPS can be built in such a way less memory is required to just do the housekeeping.
Of course, that would imply careful provisioning, maybe less "overselling" for the sake of lack of a term. The bottom line is how we can reduce the memory usage, while ensure individual VPS instance can still have fair share of CPU if needed.
Is there anyway in the VPS kernel config which can disable access to certain CPU core, thus reducing the number of kthreads and etc?
I do not know if i have problems with my vps but "top" output looks strange for me. It looks like apache processes have huge VIRT parameter and all processes have huge SWAP param.
My VPS 712 guaranteed and 1024 burstable. I'm running 10 virt hosts with very small traffic. Totally not more than 500 visits/day. Most of sites are static and only two are PHP.
Apache and PHP configuration are very standard.

I want to free some space
How can I do that?
how much adding php to apache will increase memory usage on a VPS? This would be php5.
I need it to use phpMyAdmin to manage my MySQL database (actual site is running off tomcat but jspmyadmin won't work for some reason).
Or can someone recommend a database design tool (I've used toad data modeler before) which I can use on my home pc to generate SQL statements for execution on the server (and please don't say notepad).
We have a server that is rebooting, we saw that free memory reaches almost 0 before the server reboot.

Those of you who work with shared hosting, how much memory per customer do you allow for PHP? What about for Ruby on Rails?

I'm starting a webhosting business in the next few months (working on the panel), and was wondering what is the best method to limit the amount of disk usage the user can use? I know about Disk Quota, but that would be a pain to use. Is there anything built into IIS7?

View 3 Replies View RelatedI'm currently playing with my dedicated server, it isn't much but for learning purposes it's more than enough.
I have CentOS 5.3 installed on the server.
It's Intel Atom 330 with 2 GB RAM.
Now my question is:
When server is running nothing but basic install memory comsumption is aroun 500-600 MB.
Today I have rsynced 11 GB of data from one of my VPSs to the ded server and the memory comsumption on the server sky rocketed to 2 GB, leaving only 56 Mb free.
Strange.. (for me)
And there was almost no (110 Kb) swap usage.
Now the memory comsumption is ~ 1.2 GB.
Since a short while back my server memory usage is 100%. The amount of
visitors decreased so the memory should be lower in consumption than before.
I suspect a newly installed script could have bugs or misuse of the
server by hackers. I don't know how to see on the server what script or
what part makes the memory use so high. I see Apache is very high but
I'm on VPS.
Technical data........
My managed dedicated server at 1and 1 has very low load, but quite slow, I was trying to figure out the reason. The top and free command ( I run at midnight without traffic), here is the result. Can anybody tell me if the memory usage is normal, anything suspicious. Look like the memory usage is high even with no traffic, but 1and 1 support say that's because it's reserved for cache.
