Teamwall

The developers dashboard.

This is the early stages Teamwall project.

Teamwall is a small dashboard the a team that develops software.

Basic idea

Show the developer the information he needs to know how the code is doing.

What can that be

Code Coverage, Live stats from servers, Incoming bugs etc.

Get started

Put everything in a directory served by a web server. You can also run node server.js which will start a server on port 8888. Find below a list of instruments which can be used to visualize ctitical information.

What you need to do is to create a teamwall.json file and put it into the root directory of teamwall. This file contains the description of the instruments to be shown (and how they are updated). Every 15 seconds the values are updated. It is totally up to you where and when to get the data from, Teamwall simply reads the urls and displays it's json data.

You need a browser with a working HTML 5 canvas to use this.

Example

Create a teamwall.json file looking like this:

[
	{
   	 "instrument":"percent",
   	 "width":"500",
   	 "height":"200",
   	 "id":"codecoverage",
   	 "title":"Code Coverage",
   	 "url":"data/codecoverage.json",
   	 "threshold_value":80
	}
]

Create a data/codecoverage.json file (data directory needs to be created) with the following content:

{"value":"81.8", "trend":"1"}

Hurray! You got your first Teamwall Dashboard. Now go and change the value and switch back to the browser.

Instruments

Attributes of all Instruments

Attribute	Definition
instrument	Name of the instrument to use, can be any of the instrument names below
width	Width of the instrument
height	Height of the instrument
id	Id of the instrument
url	Url to get updated data

All data from the data urls need to be in json format.

Percent Instrument

Instrument name : percent

Attribute	Definition
title	Title of the instrument
threshold_value	If the value from the data url is below the threshold the display will be rendered as failure

Example:

{
	"instrument":"percent",
    "width":"500",
    "height":"200",
    "id":"codecoverage",
    "title":"Code Coverage",
    "url":"data/codecoverage.json",
    "threshold_value":80
}

Data Format

Attribute	Definition
value	The value to be displayed
trend	The trend of the value (not yet implemented)

Where trend is defined as this:

Trend Value	Definition
1	Bigger value than previous
0	Same value as previous
-1	Smaller value than previous

Example:

{"value":"82.2", "trend":"1"}

Examples

Buildchain Instrument

Instrument name : buildchain

Example:

{
    "instrument":"buildchain",
    "width":"300",
    "height":"300",
    "id":"buildchain",
    "url":"data/buildchain.json"
}

Data Format

The format consists of a list of build steps.

Attribute	Definition
name	Name of the build step
status	FAILURE or SUCCESS

There can be as many buid steps as needed.

Example:

[ 
	{ "name":"unit tests", "status":"SUCCESS" }, 
	{ "name":"deploy preview", "status":"SUCCESS" },
	{ "name":"selenium preview", "status":"FAILURE" },
	{ "name":"documentation", "status":"SUCCESS" }, 
	{ "name":"deploy integration", "status":"SUCCESS" },
	{ "name":"smoke integration", "status":"SUCCESS" } 
]

Example

Build Alert Instrument

Instrument name : buildalert

This instrument is used to monitor multiple build chains. If one team has more than one product (and therefore chain) it can take up a lot of screen estate. If you have the need for multiple chains, this instrument is for you.

Example:

{
    "instrument":"buildalert",
    "width":"300",
    "height":"300",
    "id":"buildalert",
    "url":"data/buildalert.json"
}

Data Format

A list of build chains can be defined.

Attribute	Definition
name	Name of the build chain
chain	Definition of the chain

Attribute	Definition
name	Name of the build step
status	FAILURE or SUCCESS

There can be as many buid steps as needed.

Example:

[
{
  "name":"Build1",
  "chain":
          [
            { "name":"unit tests", "status":"SUCCESS" },
            { "name":"deploy preview", "status":"SUCCESS" },
            { "name":"selenium preview", "status":"FAILURE" },
            { "name":"documentation", "status":"SUCCESS" },
            { "name":"deploy integration", "status":"SUCCESS" },
            { "name":"smoke integration", "status":"SUCCESS" }
          ]
},
{
  "name":"Build2",
  "chain":
          [
            { "name":"Mega Tests", "status":"SUCCESS" },
            { "name":"prod tests", "status":"FAILURE" },
            { "name":"live tests", "status":"SUCCESS" }
          ]
}

]

Example

Number Instrument

Instrument name : number

Attribute	Definition
title	Title of the instrument
threshold_value	If the value from the data url is below the threshold the display will be rendered as failure
decimal_places	How many decimal places should be rendered
higher_is_better	The higher number is good and will be rendered as success
unit	Which unit should be rendered (not yet implemented)
show_trend	True or false is the trend should be rendered

Example:

{
 "instrument":"number",
 "width":"300",
 "height":"300",
 "id":"violations",
 "title":"Code Violations",
 "url":"data/codeviolations.json",
 "threshold_value":"5",
 "decimal_places":"0",
 "higher_is_better":false,
 "unit":"#",
 "show_trend": true
}

Data Format

Attribute	Definition
value	The value to be displayed
trend	The trend of the value

Where trend is defined as this:

Trend Value	Definition
1	Bigger value than previous
0	Same value as previous
-1	Smaller value than previous

Example:

{"value":"9", "trend":"0"}

TODO

• Better Layouting options
• More Instruments
