DESCRIPTION:

Ruby Stats helps you get your system statistics whenever you need it. We use it internally to monitor our Servers and send it to our monitoring servers in the cloud. This Gem currently supports Ubuntu and Mac. Unfortunately we have no plans to bring it for Windows.

Here are some of the statistics you can get about your system:

• CPU Usage
• CPU load
• Memory Usage
• Disk Statistics (Free Space, etc)
• TCP/UDP Packet Exchanges
• Gets some data about the processes that are running

Getting Started

gem install psm-ruby-stats

require 'psm-ruby-stats'

server_stats = RubyStatsPsm

server_stats.uw_diskused_perc
server_stats.uw_cpuused
server_stats.uw_tcpused
server_stats.uw_udpused
server_stats.uw_memused
server_stats.uw_load
server_stats.uw_bandrx
server_stats.uw_bandtx
server_stats.uw_diskioreads
server_stats.uw_diskiowrites
server_stats.uw_cputop
server_stats.uw_memtop

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
