Grafana creates beautiful metrics & analitics dashboards.

Introduction

Usually people spend a lot of time solving trivial problems and a lot of problems can be solved by end users.

If we join a wiki (Mediawiki) for documentation and a tool (Grafana) for creating dashboards with metrics & analytics we obtain a powerful tool. System administrators can create instructions with panels updated in realtime. (Also you can use Nagvis extension to monitor alarms, warnings, etc.)

Check usage

• Check Grafana extension

Installation

1. Download the extension (tgz) or (zip).
2. Upload Grafana directory to your extensions directory from the root of your MediaWiki installation.
3. Add require_once "$IP/extensions/Grafana/Grafana.php"; to your LocalSettings.php file (near the end).
4. Done

Usage

To insert a Grafana panel add the tag on any page:

<Grafana showheader=no urlgrafana=http://grafana_server_url dashboard="Dashboard name" panelposition=1>Grafana panel</Grafana>

Tag attributes

The following arguments (tag attributes) can be used to control <Grafana> tags:

Mandatory

showheader (yes/no)

Show a title for the panel and an icon to link Grafana server.

urlgrafana

Grafana url (Extension will check if it's a correct Grafana site)

dashboard

Name of the dashboard in Grafana Server

papelposition

It's the position of the panel in the dashboard (panelposition=1 it's the first panel in row 1).

For example if we have 3 rows (row 1 with 2 panels, row 2 with 1 panel and row 3 with 3 panels)

and we want to select panel 2 in row 3:

panelposition = 5 -> 2 (panels in row 1) + 1 (panels in row 2) + 2 (panel in row 3)

Optional

var-templatename

Include params for templates, we need to add an argument with the prefix "var-"

and templateparamname. For example to add var $macrolan:

var-macrolan=template_var_value

width

Panel width

height

Panel height

theme

Grafana theme (dark, light, etc.)

Example

<Grafana showheader=no width=450 height=200 theme=light urlgrafana=http://yourgrafanaserver.com dashboard="Macrolan" panelposition=2 var-macrolan=macrolan_line>Grafana panel</Grafana>

Notes about authentication

(See Grafana configuration site)

For a better experience with Grafana extension you need to enable anonymous access in $GRAFANA_WORKING_DIR/conf/defaults.ini

[auth.anonymous]
enabled:  Set to true to enable anonymous access. Defaults to false
org_name: Set the organization name that should be used for anonymous users. If you change your organization name in the Grafana UI this setting needs to be updated to match the new name.
org_role: Specify role for anonymous users. Defaults to Viewer, other valid options are Editor and Admin.

Notes about proxy

If your Grafana Server is behind a proxy you need to enable proxy in $MEDIAWIKI_WORKING_DIR/extensions/Grafana/Grafana.php

  $PROXY_ENABLE        = $YES;                           // $YES/$NO
  $PROXY_HOST          = "proxy_server";                 // Proxy server address
  $PROXY_PORT          = "proxy_port";                   // Proxy server port
  $PROXY_USER          = "user";                         // Username
  $PROXY_PASS          = "password";                     // Password
