Vaping

vaping is a healthy alternative to smokeping!*

(This statement has not been evaluated by the Food and Drug Administration)

Introduction

Vaping provides the following features:

Real-time latency graphing viewable in the browser
Line and smokestack graphs
Containerized and easy to setup and configure
Support for time-series databases
Plugin-based design to allow integration with other services
Supports distributed setups through message queue

Vaping is a Python daemon which polls for input and sends its output through plugins.

It has a standalone mode to directly serve realtime graphs in a browser, or can use ZeroMQ to distribute messages.

Installation

pip install vaping

You will need a compiler and Python development libraries for some components, which you can obtain with the gcc and python-devel packages for your operating system.

Alternatively, you can use the Docker image, which includes all requirements.

Quick Start

To use Vaping, you need first a configuration file that defines which hosts to target and where to send the output. You can have a look at the examples in this repository and adapt them to your needs.

Then, start the vaping program from the command line, specifying the path to the configuration file.

A quick start example is available here. It shows you how to ping multiple hosts and display the resulting graphs using a local web server.
