Build Status

HopGlass

HopGlass is a frontend for the HopGlass Server.

Screenshots

Dependencies

  • NodeJS
  • yarn (recommended) or npm

Installing dependencies

Install npm package-manager. On Debian-like systems run:

sudo apt-get install nodejs

Note: The official Debian packages for NodeJS are quite old, you might want to check at NodeSource for current binaries installable with your distribution's package manager.

On Mac you can install nodejs and yarn via brew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install node
brew install yarn

On Arch Linux you can install nodejs and yarn via pacman:

sudo pacman -S nodejs yarn

Execute these commands on your server as a normal user to prepare the dependencies:

git clone https://github.com/hopglass/hopglass
cd hopglass
yarn install # or `npm install`

Building

Just run the following command from the hopglass directory:

node_modules/.bin/grunt

This will generate build/ containing all required files.

Configure

Copy config.json.example to build/config.json and change it to match your community.

dataPath (string/array)

dataPath can be either a string containing the address of a HopGlass Server or an array containing multiple addresses. Don't forget the trailing slash! Also, proxying the data through a webserver will allow GZip and thus will greatly reduce bandwidth consumption. It may help with firewall problems too.

siteName (string)

Change this to match your communities' name. It will be used in various places.

mapSigmaScale (float)

This affects the initial scale of the map. Greater values will show a larger area. Values like 1.0 and 0.5 might be good choices.

showContact (bool)

Setting this to false will hide contact information for nodes.

maxAge (integer)

Nodes being online for less than maxAge days are considered "new". Likewise, nodes being offline for more than than maxAge days are considered "lost".

mapLayers (List)

A list of objects describing map layers. Each object has at least name property and optionally url and config properties. If no url is supplied name is assumed to name a Leaflet-provider. If no maxZoom was given in the config property, the leaflet default maxZoom of 18 is assumed.

fixedCenter (array, optional)

This option allows to fix the map at one specific coordinate depending on following case-sensitive parameters:

  • lat latitude of the center point
  • lng longitude of the center point
  • radius visible radius around the center in km

Examples for fixedCenter:

"fixedCenter": {
  "lat": 50.80,
  "lng": 12.07,
  "radius": 30
}

nodeInfos (array, optional)

This option allows to show node statistics depending on following case-sensitive parameters:

  • name caption of statistics segment in infobox
  • href absolute or relative URL to statistics image
  • thumbnail absolute or relative URL to thumbnail image, can be the same like href
  • caption is shown, if thumbnail is not present (no thumbnail in infobox)

To insert current node-id in either href, thumbnail or caption you can use the case-sensitive template string {NODE_ID}.

Examples for nodeInfos:

"nodeInfos": [

  { "name": "Clientstatistik",
    "href": "stats/dashboard/db/node-byid?var-nodeid={NODE_ID}",
    "thumbnail": "stats/render/dashboard-solo/db/node-byid?panelId=1&fullscreen&theme=light&width=600&height=300&var-nodeid={NODE_ID}",
    "caption": "Knoten {NODE_ID}"
  },
  { "name": "Uptime",
    "href": "stats/dashboard/db/node-byid?var-nodeid={NODE_ID}",
    "thumbnail": "stats/render/dashboard-solo/db/node-byid?panelId=2&fullscreen&theme=light&width=600&height=300&var-nodeid={NODE_ID}",
    "caption": "Knoten {NODE_ID}"
  }
]

In order to have statistics images available, you have to set up an instance of each Prometheus and Grafana.

globalInfos (array, optional)

This option allows to show global statistics on statistics page depending on following case-sensitive parameters:

  • name caption of statistics segment in infobox
  • href absolute or relative URL to statistics image
  • thumbnail absolute or relative URL to thumbnail image, can be the same like href
  • caption is shown, if thumbnail is not present (no thumbnail in infobox)

In contrast to nodeInfos there is no template substitution in href, thumbnail or caption.

Examples for globalInfos using Grafana server rendering:

"globalInfos": [
  { "name": "Wochenstatistik",
    "href": "stats/render/render/dashboard-solo/db/global?panelId=1&fullscreen&theme=light&width=600&height=300",
    "thumbnail": "nodes/globalGraph.png",
    "caption": "Bild mit Wochenstatistik"
  }
]

linkInfos (array, optional)

This option allows to show link statistics depending on the following case-sensitive parameters:

  • name caption of statistics segment in infobox
  • href absolute or relative URL to statistics image
  • thumbnail absolute or relative URL to thumbnail image, can be the same like href
  • caption is shown, if thumbnail is not present (no thumbnail in infobox)

To insert the source or target node-id in either href, thumbnail or caption you can use the case-sensitive template strings {SOURCE} and {TARGET}.

"linkInfos": [
  { "href": "stats/dashboard/db/links?var-source={SOURCE}&var-target={TARGET}",
    "thumbnail": "stats/render/dashboard-solo/db/links?panelId=1&fullscreen&theme=light&width=800&height=600&var-source={SOURCE}&var-target={TARGET}"
  }
]

siteNames (array, optional)

In this array name definitions for site statistics and node info can be saved. This requires one object for each site code. This object must contain:

  • site the site code
  • name the defined written name for this site code

If neither siteNames nor showSites are set, site statistics and node info won't be displayed

Example for siteNames:

"siteNames": [
  { "site": "ffhl", "name": "Lübeck" },
  { "site": "ffeh", "name": "Entenhausen" ),
  { "site": "ffgt", "name": "Gothamcity" },
  { "site": "ffal", "name": "Atlantis" }
]
You can’t perform that action at this time.
