Webtime Munin Plugin

Plugin to graph HTTP response time of a specific page

This is a Virtual Node plugin. This mean that it can run on any regular node (or on the Munin master), and each instance (symlink) can point to an external devices. Here is a usefull link that explains how to setup a virtual node.

Installation

  • Copy webtime_ to the main Munin plugin directory, ie :/usr/share/munin/plugins/
  • Then symlink it from the /etc/munin/plugins/ folder, carefully naming it as described below
  • Update the /etc/munin/munin.conf adding your node hostname between brackets, and set the address parameter to the IP of the node where webtime_ is installed. Example, if the node is on the same host as the server :
# hostname fetched by the node (must be the SAME as the HOSTNAME defined in the symlink name)
[www.apple.com]
      address 127.0.0.1
      # this the address of the NODE containing the symlink to webtime_

Wilcard Naming

Link to this file with a symlink named as webtime_HOSTNAME_PAGENAME where:

  • HOSTNAME is the HostName to fetch.
  • PAGENAME is the name of the page ('-' are replaced by spaces)

example: webtime_www.apple.com_HomePage

ENV Settings

You can add the following "env.xx" inside the [iot-json_HOSTNAME_FIRMWARE_TYPE] definitions in /etc/munin/plugin-conf.d/

  • env.url : the relative URL from the host (defaults to '/')
  • env.host : use a different hostname than the one defined from the symlink name
  • env.name : use a different pagename than the one defined from the symlink name
  • env.scheme : scheme to use (defaults to 'http://')
  • env.agent : UserAgent (defaults to 'Mozilla/5.0 (Linux; Munin; http://www.github/soif/munin_plugins) webtime_/1.0')
