I want to measure memory utilization of my Apache Server. Can I use pmap command and pass all the process ID of 'httpd' and take that as total utilization ?
pmap PID1 PID2 ....
It seems that pmap give more info rather than RAM utilization. Any command in Unix/Perl through I get the correct info of memory utilization ?
I have been getting requests from application teams that the server is running slow. I have checked the memory utilization, processes running and cpu utilization. Please find below:
#free -m
total used free shared buffers cached
Mem: 3006 2994 11 0 6 171
When I execute command df -h /tmp it says disk utilization is 100% but when it tried du -sh /tmp it says disk utilization is 2%.
I want to know why these commands shows different output and these two commands work and what is the solution of this problem.
dear all,
kindly i want to check my server memory utilization i used alot of commands but i want to make sure that it is acurate let me explain
i have a server which has 32GB RAM
Total Memory = 33423360 kb
Free Memory = 4172568 kb
Utilized Memory = 29250792 kb
Memory Utilization Percentage = 87.5 %
if Utilized Memory = 29250792 kb how can i make sure which processes eat this amount of memo
We have a university cluster consisting of 1 NFS server, and 40 client nodes. We are having problem recently where the NFS processes on the server shoot to 100% CPU utilization, and the whole cluster becomes unusable.
We have found that a majority of the client nodes have a kernel thread [192.168.140.2-m] that are CPU bound, talking to the NFS server.
Hi all,
I just wonder if anyone can give some hint regarding my problem. I have a server based on RHEL 4.4

Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process.
We have an EC2 instance (Ubuntu) that has a few java-based applications and lately we're getting hit with high CPU utilization spikes that trigger one of our Cloudwatch alarms. By the time we get into the server to look at the cpu utilization, things have calmed down.
