passenger-memory-stats(8) Administration Commands passenger-memory-stats(8)NAME
passenger-memory-stats - reports a snapshot of the Apache and Phusion Passenger memory statistcs
SYNOPSIS
passenger-memory-stats
DESCRIPTION
passenger-memory-stats allows you to easily analyze the real memory usage of Phusion Passenger and Apache.
Process inspection tools such as ps and top are useful, but they rarely show the correct memory usage. The real memory usage is usually
lower than what ps and top report.
There are many technical reasons why this is so, but an explanation is beyond the scope of this page. We refer the interested reader to
operating systems literature about virtual memory and copy-on-write.
When you run this tool the Private or private dirty RSS field shows the real memory usage of processes.
ENVIRONMENT VARIABLES
HTTPD The full filename to the Apache executable. By default, Passenger will attempt to autodetect the Apache executable. If autodetection
fails for whatever reason, then Apache processes will not be shown in the memory statistics. In that case, you may manually specify
the location to the Apache executable using this environment variable.

Apache::Session::Serialize::Sybase(3pm) User Contributed Perl Documentation Apache::Session::Serialize::Sybase(3pm)NAME
Apache::Session::Serialize::Sybase - Use Storable to zip up persistent data and unpack/pack to put into Sybase-compatible image field
SYNOPSIS
use Apache::Session::Serialize::Sybase;
$zipped = Apache::Session::Serialize::Sybase::serialize($ref);
$ref = Apache::Session::Serialize::Sybase::unserialize($zipped);
DESCRIPTION
This module fulfills the serialization interface of Apache::Session by taking the data from Apache::Session::Serialize::Storable and
modifying it to work with Sybase IMAGE fields. Note that you do not need to quote these values before inserting into the database, and that
if you are using DBI::Sybase, you cannot use the data in a placeholder. If you use Apache::Session::Sybase as your session class, this will
all get taken care of.

Is there a way to collect data from top command to a file at regular intervals. I need this on HP-UX. I need to gather resident memory usage. I know that sar will give %cpu usage. There is a pmap command which gives memory usage in solaris. Is there a similar command in HP-UX
Thanks (5 Replies)
Hello,
I'm working with Linux 2.4.18
I'll like to know, if there is a way to know exactly what is using the RAM memory of my box.
I try with ps command, but the size of the memory usage than I can calculate, it is very diferent compared with the information that I get with the free command.

I've been asked to gather CPU, memory and disk stats in the following format:
Cpu_Max Cpu_Min Cpu_Avg Mem_Max Mem_Min Mem_Avg Disk_Max Disk_Min Disk_Avg
Can anyone please tell me a command to gather all this info?
Thanks!

Hi I'm writing a script to get overall system memory and cpu utilization in percentages, much like in top or with AIX's topas.
Could I use 'ps' to get the same, I know I can get such results for a particular or group of PIDs but I haven't been able to figure out how I could use 'ps' to give me... (10 Replies)

Hi,
Yersterday I started monitoring my homeserver memory consumition due some errors found in the system (network hangs). I've detected almost all the memory used (~10 MB free from 1GB).

Hi, i have 2 identical web servers using AIX. I use nmon analyser to check their performance.
The server A exceeds 20% memory usage for system, 5% for cache and the rest 75% for processes. While, it uses 4% of Paging Space.
The server B exceeds 20% for system, 45% for cache and 35% for processes.... (24 Replies)
Hi,
This morning there was an app that caused a sudden spike in I/O and memory usage in the server. We found the reason for the I/O, however the memory spike was something new, as it had never happened before.
I figured out what caused the memory spike, however, how do I investigate why... (6 Replies)
