Server :: Way To Show / Count How Many CPU Instruction Particular Process Using -or Uses?
Feb 5, 2010
Is there a way to show or count how many CPU instructions a particular process is using or uses?
In my work we develop a web application and I'm responsible of maintaining the web server.
The app lets you handle data online so each client that uses the web application has a folder associated to it, where his data is stored. (/var/www/html/test) for example.
The idea is to get how many CPU instructions the httpd process for that particular folder is having. Is there a way to do this?

This has to also show the line count. I can get it to show the files but not the line count. What is the single command used to identify only the matching count of all lines within files under the /etc directory that contain the word „HOST? List only the files with matches and suppress any error messages.

Is it possible, using ps, to determine where a process is running from? I have two applications, both are identical and running in parallel directories, such as /app1/start.sh and /app2/start.sh. If I run ps -ef then I'm unable to tell the difference between the two
Using ps (or alternative), how can I tell that PID 123 belongs to app1?

Is there a command to count inodes with in a directory?
I know I can see total inode usage with:
df -i
And I know I can find total number of files with:
find ./ |wc -l
But how can I find inodes? As files over 8kb (if using the default partitioning of 1 node over 2 4kb blocks) would take up more than 1 inode.

Someone at work has requested if i can find out anything on the above.Been googling around as well as i have only been using Linux for 2 months now.
basically there is a SYBASE ASE installation on the server, which a tomcat based website references.They want the service to stop once a certain row limit is reached in the table.
I know i have to do a count statement on the sybase table from ISQL.But how can i create the action "service website stop" once the count value reaches 4000 ?

Previously I had posted a question on how to make it run every 7 minutes between 7 and and 11pm.However now I found out what I really need is every 7 minuted between 7:30 and 11pm BUT it has to be every 7 minutes, it cannot reset itself on the top of every hour, so the */7 wont work.How can it that it will be every 7 minutes, so it will go at 7:30, 37,44,51, 58, 8:05, etc..

I burned the Slackware 13.1 DVD disk, and installed on a desktop, and it worked really great. Now, I would like to install 13.1 on my laptop, but my DVD-rom doesn't work. So is there any instruction for me to upgrade from slackware 12.1 (currently running)to slackware 13.1 directly, like what states in "Slackware 13.0 to 13.1 Upgrade HOWTO" ? Alternatively, is there any way that I can install slackware 13.1 from the ISO image file on my Windows partition? or I just following the instructions off this website, [URL]

I'm reading "Understanding the Linux Kernel" and came upon this assembly instruction:
movl $(__KERNEL_CS << 16), %eax
I am curious as to what "<<" means/does. I tried to gooogle, but google doesn't search for "<<".

All I want to do is fade some text in and out via the opacity attribute, and change the text when it hits zero. My script changes the text on time, but ignores the formatting effects. I'm not worried at this stage about the else statement in the startFadeEffect() function. I just want the fade effect to work here the way it should.

I have a server that runs on a static IP address with many hosting accounts. I am using the IspCP to manage the different sites. When a mail is sent, the headers include the box's own domain name: [URL]. Now [URL] is no longer active, so if an email from another account: [URL] sends mail, there is possibility that this mail is rejected by the receiver, if the receiver system does rDNS.
The receiving server will check the headers smtp sent from [URL] and come up as a fake, because [URL] is no longer registered. I wonder if there is a way to make the smtp headers reflect only the domain name that sent the mail. Then if joe sends mail, the server should replace[URL] with [URL]. If this is possible, then users that send mail will not get bounced because the rDNS lookup will map [URL] to the ip and the mail will be accepted.

I have a laptop with Redhat 5 installed and a Windows 7 Virtual Machine. The laptop is connected to the internet but I cant access any web pages in firefox - it just comes up with Server Not Found (tried all different sites). I know the internet connection is good as if i go into my windows VM firefox works normal. Ive checked the network settings and tried setting to 'no proxy' and automatically detect but nothing seems to work. Ive uninstalled and reinstalled firefox and still get the same.
Ive tried both wired and wireless but makes no difference. Seems really weird that it works in the Windows VM but not in Redhat which its booting into.

I am running squid 2.6 (as proxy server) in cent os 5. When I use the following command I see
Code:
#tail -f /var/log/squid/access.log
i can always see
TCP_MISS
TCP_REFRESH_MISS
TCP_CLIENT_MISS
which means that the client computer does not gain web pages from squid cache. If the client gain access gain then there should be
TCP_HIT,
TCP_REFRESH_HIT
TCP_REFRESH_HIT/200
but unfortunately I can not see this message There is no problem with the client side and they are happy but being a system admin it is a serious thing that why there is no chance to see TCP_REFRESH_HIT. The squid cache size is only 2GB.
