usagewatch extended version

DESCRIPTION:

This project is based in Usagewatch gem written by Phil Chen, I try to expand the OS version, first with mac OS, in future versions Windows will be include.

This is Ruby Gem with methods to find usage statistics on your system such as CPU, Disk, TCP/UDP Connections, Load, Bandwidth, Disk I/O, and Memory, top processes by memory and cpu consumption

Getting Started

gem install usagewatch_ext

require 'usagewatch_ext'

usw = UsagewatchExt

Example

Run:

linux_example.rb

Example Output:

11.56 Gigabytes Disk Used
7.0% Disk Used
0.25% CPU Used
30 TCP Connections Used
0 UDP Connections Used
43% Active Memory Used
0.01 Average System Load Of The Past Minute
0.008 Mbit/s Current Bandwidth Received
0.2 Mbit/s Current Bandwidth Transmitted
0/s Current Disk Reads Completed
2/s Current Disk Writes Completed
Top Ten Processes By CPU Consumption:
[["/usr/lib64/erlang/erts-5.8.5/bin/beam.smp", "5.2"], ["ruby", "4.1"], ["ps", "2.0"], ["abrt-dump-oops", "0.8"], ["aoe_ktio", "0.7"], ["aoe_tx", "0.4"], ["ata_sff", "0.2"], ["auditd", "0.1"], ["awk", "0.1"], ["-bash", "0.1"]]
Top Ten Processes By Memory Consumption:

Example Output:

Mac version is under development
92.8 Gigabytes Used
24.96 Percentage of Gigabytes Used
71.47% Active Memory Used

Notes

Disk Used is a sum of all partitions calculated in Gigabytes

Disk Used Percentage is a total percentage of all disk partitions used

CPU Used is a percentage of current CPU being used

TCP/UDP Connections Used is a total count of each respectively

Active Memory Used is a percentage of active system memory being used

Load is the average load of the past minute

Bandwidth is current received and transmitted in Megabits

Disk IO is current disk reads and writes completed per second

Top Ten Processes By CPU Consumption are based on percent CPU used

Top Ten Processes By Memory Consumption are base on percent Memory used
