usagewatch extended version

DESCRIPTION:

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

Also I am writing a testing library for the original gem.

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 = Usagewatch

usw.uw_diskused
usw.uw_diskused_perc
usw.uw_cpuused
usw.uw_tcpused
usw.uw_udpused
usw.uw_memused
usw.uw_load
usw.uw_bandrx
usw.uw_bandtx
usw.uw_diskioreads
usw.uw_diskiowrites
usw.uw_cputop
usw.uw_memtop
usw.uw_apacheconns

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:

Run:

mac_example.rb

Example Output:

Mac version is under development
92.8 Gigabytes Used
24.96 Percentage of Gigabytes Used
71.47% Active Memory Used
7.69% CPU Used
1.19 Average System Load Of The Past Minute
Top Ten Processes By CPU Consumption: [["PluginProcess", "9.0"], ["WindowServer", "2.7"], ["iPhoto", "1.2"], ["Terminal", "1.0"], ["rubymine", "0.5"], ["SystemUIServer", "0.1"], ["(scanunit)", "0.0"], ["(scanunit)", "0.0"], ["(scanunit)", "0.0"], ["(scanunit)", "0.0"]]

Notes

Disk Used is a sum of all partitions calculated in Gigabytes
Disk Used Percentage is a total percentage of all disk partitions used
Disk Used On is disk space used on the location passed calculated in Gigabytes, returns "location invalid" if invalid location passed
Disk Available is a sum of all partitions calculated in Gigabytes
Disk Available On is disk space available on the location passed calculated in Gigabytes, returns "location invalid" if invalid location passed
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
HTTP Conns is the number of connections on 80 port
