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.
Software :: 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.
General :: Windows 7 - Order In The Slots Of Memory Modules Matter/ MemTest?
Apr 4, 2011In a new PC I had constantly BSoD. I tracked it down to bad memory modules and took them back to the shop.Specifically the RAM was Corsair. Anyway they said they will do test on memory to confirm. They did tests and admitted the RAM was faulty and gave me a replacement. At this point: originally I bought 2 kits of 4G RAM. One of the kits turned out bad. They gave me a replacement, it does not seem to be exactly the same, though. In any case, I became causious and as soon as I got them I put them in the PC and run KUbuntu memtest. It started showing thousands of errors! (Again!). I removed the new kit and run the test again. No errors. I swapped the slots I put the memory modules and also no errors. I can not understand now. Is the new RAM kit bad or not? Does the slots I place the kits matter?

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:

Ubuntu :: Terminal Command To List Disk Usage In Order?
Mar 29, 2010I regularly use 'df -h' to check usage on each of my primary directories and mount points.
I'm currently somewhat confused by disk usage within my filesystem, so I'd like to do the following:
Display directory size of all, or say, the 10 largest, subdirectories to a specified directory. So, if I passed the root (/) directory, output would list the subdirectory of / with the largest disk usage first and its associated disk usage listed in human readable format (either M or G suffix as appropriate), followed by the subdirectory and usage for the second largest directory and so on.
Can anyone suggest a command or series of commands to do this?
