On Windows 7 and Windows 2008 SP2, how can I view who or what is using up my memory?
There are several discussions complaining high memory usage of PHP-FPM, without any practical approach to overcome. As I explored the problem with numerous tests, the problem is related to the age of PHP-FPM age.
Imagine we have pm.max_children = 10, and have a PHP script consuming 10M memory. One expects needing 100MB of MB. This is correct for the first 10 processes.
I'm trying to calculate the amount of memory used by AMP in an LAMP stack machine.
top -bn1 | grep -E '(mysql|httpd|php)' | awk '{mem += $(NF-2)} END {print mem}'
But the sum generated using the above command is greater than 100%, but I was expecting something below 100% since individual processes memory usage is already represented in % by top.
Please help me understand whether memory reported
I want to Limit cpu and memory usage for php-fpm and nginx processes in centos.
I came across following tools
cpulimit
cggroups
memory resource locater
which will more efficient and how can I configure for limiting resources for php-fpm and nginx processes ?
I know how to get memory usage of a process with given pid,
but how to get the memory usage of a task?
If I understand it correctly, a task/application may have multiple processes.
If so, then the question becomes how to know the processes(pids) of a task?
I'm using cgroups with the memory controller to set a memory limit for each user (using the memory.limit_in_bytes setting).
The problem is that this setting also accounts cache usage. Therefore, if the limit is 1GB, and the user merely downloads or copies a 1GB file, their processes get killed.
I'm running Ubuntu server 12.04 on a computer at home, granted it's a netbook so there's not a lot of performance to squeeze out of it, but I'm still wondering about the memory usage I'm seeing from /usr/sbin/mysqld.
When I run htop and sort by memory usage, I get 16 processes on top, all of them running from the mysqluser and pointing at the command /usr/sbin/mysqld.
I have a home server sometimes running at a high CPU usage rate of about 50 to 70 percents.
In htop, my favorite process manager, I can sort the processes by CPU usage, but often there isn't any process consuming more than 0 % CPU.
i am using ubuntu 12.04LTS on my linode vps include core2 cpu, 2gb RAM. I am doing a lot of research on optimizing memory for mysql and apache process -> optimize apache memory use, there i am using two scripts for compute memory per process.
