Average Apache CPU And Memory Usage

Aug 14, 2008

tell me what the average usage of the CPU and RAM be from apache?

User 'Nobody' (Which I presume is apache) is using 13% CPU and 38.98% of RAM. Is this normal or is it well overloaded?

Apache Memory Usage, Why So Different On 2 VPSs

Mar 24, 2009

I currently have 2 VPSs that I'm monitoring and I noticed that on one of them the memory usage is much higher than the other which doesn't make sense to me. I tracked the high memory usage to the Apache processes.

Here's the overview of the VPSs:

LiquidWeb VPS- 512MB RAM, 10 Sites with minimal usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 1.2 /usr/local/apache/bin/httpd -k start -DSSL

Virpus VPS- 384MB RAM, 61 sites with moderate usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 0.3 /usr/local/apache/bin/httpd -k start -DSSL

Both Apache configurations are identical, the only difference besides the hardware is that LiquidWeb runs CentOS4.7 and Virpus runs CentOS5.2, any ideas? It's not to big of a deal since I'm not near my limit for either of them but I was just curious.

Apache Memory / Cpu Usage / Magento

Jul 31, 2014

I'm running a single Magento website with only around 150 products, and very low traffic, on a VPS with 2 Cores and 4GB of ram. However I am getting constant warning emails about high Apache Memory usage and High CPU usage.

The server and site were working fine, however since the server failed (Power cut on upgrade at the hosts end) and we rebuilt the website I'm getting these warnings, my host said it is just the website and the server needed upgrading... to which I did (server was a 1 core 2GB ram server). However since I've upgraded I'm still getting these warning emails.

Here is the latest one: URL...

4951 apache 20 0 441m 137m 6556 S 0.0 3.6 2:28.77 httpd
4952 apache 20 0 443m 139m 7168 S 0.0 3.6 2:43.72 httpd
7377 apache 20 0 358m 54m 6576 S 0.0 1.4 1:25.76 httpd
7692 apache 20 0 433m 129m 6588 S 0.0 3.4 1:20.64 httpd


I'm really new to VPS's and plesk so I'm wondering what I can do to try and track down what is causing these high usage as I'm 100% certain the site was fine before. The server has default build both before and after the fail.

Server Information:
OSCentOS 6.5 (Final)
Panel version11.5.30 Update #47
2 Cores
4GB Ram

Are there any tools within plesk that I can use to see what is causing these issues? It's making the website load extremely slow.

Plesk 11.5 - Apache Memory Usage High

Jul 20, 2014

We are currently running plesk 11.5 and over the last few months, the apache memory usage has been very high. On investigation we have gone through the logs and we can't find a cause.

I can issue a service httpd restart and the memory drops for about 30 minutes and then we see the apache memory grow to almost 1.5 - 2GB. Why this keeps happening?

DC Saying Actual Usage Is More Than Average Reports

Nov 4, 2007

I have some small colo in an a DC that I have actual transfer basis on each server. Now they give me MRTG graphs and they say they go by what the switch reports for when they bill me. I haven't had an issue until this month when one of my servers which I only have one TB with was reported using 1372GB on their switch.

Now on my MRTG graphs it reported the monthly graph as the following:

Average In: 2360.8 kb/s (2.4%) 763.855996 GB
Average Out: 471.7 kb/s (0.5%) 152.6205485 GB

This reports under 1TB, so I thought that I was okay on my usage. Am I wrong in thinking that the average usage and actual usage should be very similar? I figured since MRTG takes how much you transfer every 5 minutes and averages that over 300 seconds to find the rate that it would report basically the same average usage as my actual usage.

Average Bandwidth Usage Per Cabinet

Nov 1, 2007

I'm about to move 31 machines into a 42U full cabinet

Previously I was on an uncapped bandwidth provider but we had a lot of problems with them so I decided to find a new provider who charges bandwidth by mbps

I do not have mrtg installed or managed switches, but I may start with 10mbps.

But I'm just curious, what takes a full cabinet with more than 30 machines does the total bandwidth takes you.

Perhaps any colo provider here don't mind to share their stats.

Memory Usage :: Put More Content Into Memory?

Jul 16, 2009

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


# uname -a
Linux server2.[url]2.6.18-128.1.10.el5 #1 SMP Thu May 7 10:35:59 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

Any idea that we can put more content into memory?

Memory Usage For XEN Vs. VOZ

Jun 23, 2009

It 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}'

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?

Php Memory Usage

Nov 1, 2007

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.

im running a cpanel server on P4 3.6HT / 1GB RAM / load always under 1.0:

46.6 to 80 requests/sec - 183.7 kB/second - 4034 B/request

top - 11:07:15 up 21 min, 1 user, load average: 0.29, 0.38, 0.46

Is the time to increase RAM server or would be a hardware problem?

Memory Usage After VPS Upgrade

Mar 23, 2009

I have a VPS with 384 MB RAM, with free about 100-120 MB. I've upgraded to 512 MB (to have some other features...). I notice that the memory usage is always about 250-300 MB. For example, now:

[root@host ~]# free -m
total used free shared buffers cached
Mem: 512 311 200 0 0 0
-/+ buffers/cache: 311 200
Swap: 0 0 0
But PHP tells "out of memory" in some tasks

The current PHP config is memory limit 192 MB (it was 96 MB, then I tried to increase).

<b>Fatal error</b>: Out of memory (allocated 19660800) (tried to allocate 39 bytes)

CentOS And Memory Usage

Oct 20, 2009

I'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.

My Server Memory Usage Is 100%

Jun 10, 2009

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.

Does The Memory Usage Statistics Look Right

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.

Memory Usage On Linux

Jul 21, 2008

I have a dedicated server with 2 GB of RAM. I am concerned with my server's memory usage when I am currently not running many applications.

[root@digm1 ~]# free -m
total used free shared buffers cached
Mem: 1947 1896 50 0 106 1579
-/+ buffers/cache: 210 1736
Swap: 2047 0 2047

It tells me that I only have 50 MB of memory left and it drops down to ~20 MB after Apache has been running for a while. Once it runs out of that 20 MB I will start swapping right? I have also run this command and do not see any process taking up anywhere close to what is being reported:

ps -eo pid,ppid,rss,vsize,pcpu,pmem,cmd -ww --sort=pid

No process is using more than 1.5% memory and only 3 use this much.

Is Linux caching memory which will be used after I run out?

Memory Usage :: Running Out Of RAM

Nov 19, 2008

I have a VPS with 512 MB ram. I have 6 sites hosted on my VPS, of which 3 contains only static pages. My site is not very traffic heavy. Infact I moved to my VPS only 3 months back, until then it was running on a shared server with no problem.

But still, I am always running out of RAM. I have upgraded my account to 512 MB ram from 256MB because of this. Can anyone please tell me how I can find out what is the cause of this excessive memory usage? On rebooting my server, the RAM usage goes down to about 250MB.
