Server Watch

============

This is script setup to allow for easy logging of various server level statistics that

is useful when doing system profiling and load testing.

Usage

-----

This is a simple Python script that can be run via 

    ./server-watch.py

    

This logs the desired values to stdout. Those can be redirected to a file as:

    ./server-watch.py > /tmp/server-data.log

    

There are a few command line options to customize the behavior

* -c, --config _config file_

    > Specifies which config file to use

* -a, --apache

    > Enable apache connection monitoring

* -m, --mysql

    > Enable mysql monitoring

* -d, --delimeter _delimeter_

    > What string to use as a delimeter for the log file, defaults to a tab

* -s, --seconds _delay_

    > How many seconds to delay b/w report rows, defaults to 1 second

Configuration File

* 5: %nice - CPU % at user w/ nice

* 6: %sys - CPU % at kernel

* 7: %iowait - CPU % at kernel in iowait 

* 8: %irq - CPU % serving interrupts

* 9: %soft - CPU % serving soft interrupts

* 10: %steal - CPU % at involuntary wait (hypervisor)

* 11: %idle = CPU % idle

* 12: Physical memory used

* 13: Physical memory free

* 14: Swap memory used

* 15: Swap memory free

* 16: Memory in page cache 

* 17: Number of apache processes
