General :: Multithreaded Application / CPU And Memory Usage
Feb 14, 2009We run Jboss app server that of course is all multithreaded under one JVM. I have couple of question regarding monitoring on per thread basis:

2. Is there a way to see the CPU, Memory usage per thread? Something like prstat on Sun box which is real time and gives detailed information about threads per CPU
General :: Calculating Process Memory Usage?
May 13, 2010What originally seemed like an easy thing to calculate has given me a big headache. Perhaps someone can help me with my issue. I am trying to find, in particular, how much memory certain application processes are taking. The process always is the same name, main_server, but with an argument to tell it what to do when running as a daemon.
When running the following command against all "main_server" processes, it produces a result in megabytes based on the output of the rss field in 'ps'.
Code:
CALC=0
for ea in
`ps -e -orss=,args= |
sort -b -k1,1n |
pr -TW$COLUMNS |
grep main_server |
grep -v "grep main_server" |
[Code]...
Currently I am left scratching my head. For capacity planning purposes, it would be nice to know how many more 'main_server' processes could run on the system without causing it to swap. Knowing the buffer and cache usage will go down as running processes demand more memory, I prefer to look at the free memory excluding cache and buffers. However, since 'ps' is reporting the processes are using more memory than free reports is in use without those things, I have no way to know how many more processes the system can support. I played around with different fields in 'ps', such as vsize, size, etc, but with no luck in matching up any numbers.

View 3 Replies View RelatedSoftware :: Memory Usage General Definitions On Top ?
Oct 27, 2009I was playing with top to understand ram memory usage of every thread but i am in trouble with some basic questions:
- what difference is between 'thread' and 'process'?
- what does 'virtual image size' means, and Resident size, Shared Mem size, Code size, Data+Stack size, Swapped size? I thought that the only important field is 'Memory usage', but it is represented as a percent value...
I have googled a bit, but nothing really helped me. before opening top i thought that memory is divided in several pages by every process/thread (?) and that this occupied memory would be counted as 'used memory', and nothing else.

Server :: "free" Shows Far More Memory Usage Than Summing Up Application Usage?
Aug 6, 2010I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Code:
[root@server1 ~]# free -m
total used free shared buffers cached

Code:
[sam@system43~]$sudo /sbin/fdisk -l
Password: But in ubuntu, after the same configuration being done, what sam needs to do is:
Code:
