Getting Started

With packages

See Sensu documentation

From source

Prerequisites

• Recent version of git
• Recent version of npm (guide)
• Recent version of go (guide)

Installation

• Checkout the source: go get github.com/sensu/uchiwa && cd $GOPATH/src/github.com/sensu/uchiwa
• Install third-party libraries:
  • With standard user: npm install --production
  • With root user: npm install --production --unsafe-perm
• Copy config.json.example to config.json - modify your Sensu API information. See configuration section below
• Start the dashboard: go run uchiwa.go
• Open your browser: http://localhost:3000/

Configuration

sensu

• name - String: Name of the Sensu API (used as datacenter name). If empty, a random one will be generated.
• host - String: The address of the Sensu API. Required.
• port - Integer: The port of the Sensu API. The default value is 4567. Required
• ssl - Boolean: Determines whether or not to use the HTTPS protocol. The default value is false.
• path - String: The path of the Sensu API. Leave empty in case of doubt
• user - String: The username of the Sensu API. Leave empty for none.
• pass - String: The password of the Sensu API. Leave empty for none.
• timeout - Integer: Timeout for the Sensu API, in seconds. The default value is 5.

uchiwa

• host - String: The address on which Uchiwa will listen. The default value is 0.0.0.0.
• port - Integer: The port on which Uchiwa will listen. The default value is 3000.
• user - String: The username of the Uchiwa dashboard. Leave empty for none.
• pass - String: The password of the Uchiwa dashboard. Leave empty for none.
• refresh - Integer: Determines the interval to pull the Sensu APIs, in seconds. The default value is 5.

Docker

This application comes pre-packaged in a docker container for easy deployment.

There are two ways of running this container:

Docker with a config file.

Make a config.json file for the application, and then launch the uchiwa container with the config mounted as a volume.

# Create a folder that will be mount as a volume to the Docker container
mkdir ~/uchiwa-config
# Copy your uchiwa config into this last folder
cp ~/uchiwa/config.json ~/uchiwa-config/config.json
# Start Docker container. It will listen on port 3000 by default
docker run -v ~/uchiwa-config:/config uchiwa/uchiwa

Docker with environment variables

You can instead use environment variables to configure the application. Host is fixed to 0.0.0.0 and port to 3000, but the other settings can be set:

• UCHIWA_USER
• UCHIWA_PASS
• UCHIWA_REFRESH

And configuring an API is done with other environment variables which are designed to fit into Docker's container links (allowing you to point uchiwa at an API just be --linking it to that container)

You can link multiple APIs by providing multiple sets of environment variables with different prefixes.

These variables are mandatory.

• API1_PORT_4567_TCP_PORT - The port for the API, usually 4567
• API1_PORT_4567_TCP_ADDR - The hostname or IP for the API

These variables are optional

• API1_UCHIWA_NAME
• API1_UCHIWA_SSL
• API1_UCHIWA_USER
• API1_UCHIWA_PASS
• API1_UCHIWA_PATH
• API1_UCHIWA_TIMEOUT

An example of starting the container with the minimum set of environment needed would be:

docker run -i -t -p 3000 -e API1_PORT_4567_TCP_PORT=3000 -e API1_PORT_4567_TCP_ADDR="1.1.1.1" uchiwa/uchiwa

Health

You may easily monitor Uchiwa and the Sensu API endpoints with the /health page.

/health

Returns Uchiwa and Sensu API status.

• success: 200
  • content: {"uchiwa":"ok","sensu":{"0.12.6":{"output":"ok"},"0.13.0":{"output":"ok"}}}
• error: 500
  • content: {"uchiwa":"ok","sensu":{"0.12.6":{"output":"connect ECONNREFUSED"},"0.13.0":{"output":"ok"}}}

/health/uchiwa

Returns Uchiwa status.

• success: 200
  • content: "ok"
• error: 500
  • content: "error"

/health/sensu

Returns Sensu API status.

• success: 200
  • content: "{0.12.6":{"output":"ok"},"0.13.0":{"output":"ok"}}
• error: 500
  • content: {"0.12.6":{"output":"connect ECONNREFUSED"},"0.13.0":{"output":"ok"}}

Contributing

Everyone is welcome to submit patches. Whether your pull request is a bug fix or introduces new classes or functions to the project, we kindly ask that you include tests for your changes. Even if it's just a small improvement, a test is necessary to ensure the bug is never re-introduced.

Testing

In order to install all the tools, please run npm install.

The command go test -v ./... will execute the proper unit tests.
