The alerta monitoring tool was developed with the following aims in mind:

• distributed and de-coupled so that it is SCALABLE
• minimal CONFIGURATION that easily accepts alerts from any source
• quick at-a-glance VISUALISATION with drill-down to detail

The only requirement is MongoDB. Everything else is optional.

• MongoDB

A messaging transport that supports AMQP is required for notification to alert subscribers. It is recommended to use RabbitMQ, but Redis and even MongoDB have been tested and shown to work.

• RabbitMQ
• Redis
• MongoDB

Note: The default setting uses MongoDB so that no additional configuration is required.

To install and configure on Debian/Ubuntu:

$ sudo apt-get update
$ sudo apt-get install mongodb-server

To use RabbitMQ as the message transport instead of the default MongoDB install the additional packages:

$ sudo apt-get install rabbitmq-server

To install from git:

$ git clone https://github.com/guardian/alerta.git alerta
$ cd alerta
$ sudo pip install -r requirements.txt
$ sudo python setup.py install

The configuration file format has changed in Release 3.2 to a python settings.py file. To override default settings in this file create /etc/alertad.conf or set ALERTA_SVR_CONF_FILE environment variable to ~/.alertad.conf or ~/.config/alertad or something similar. Make sure to to export the environment variable before running the server, like so:

export ALERTA_SVR_CONF_FILE=~/.alertad.conf

The default configuration should work. If you are using RabbitMQ change the AMQP_URL setting to:

AMQP_URL = 'amqp://guest:guest@localhost:5672//'

To start the alerta server simply run:

$ alertad

To send some test alerts run:

$ contrib/examples/create-alerts.sh

To view alerts in a terminal run:

$ alerta query

To view alerts in a web console install the Alerta Web UI

See the alerta docs. Documentation is a work in progress. Feedback welcome.
