os-stats

Overview

A low-overhead O/S level event collector that generates events-compatible events. It is designed to run in background, collect times events and channel them (to files, over the network, etc.) It is capable of collecting memory, CPU, etc. usage statistics, as well as WildFly management domain model and JMX metrics.

Installation

Download the stable release from

https://github.com/NovaOrdis/os-stats/releases

The release consists in a ZIP file with a name matching "os-stats-<version>.zip".

Unzip the release file in a conventional binary directory, such as /opt or /usr/local. An "os-stats-<version>" sub-directory will be created.

Add .../os-stats-<version>/bin to PATH.

os-stats needs a Java VM to run. It will attempt to locate one in this order:

  1. Value of "OS_STATS_JAVA_HOME" environment variable, if set.
  2. Value of "JAVA_HOME" environment variable, if set.
  3. The "java" executable found in path.

Choose a directory to store the configuration file. This directory will be known as the "os-stats configuration directory"

Complete any of target-specific configuration procedures, if they apply.
