Alerta Release 8.0

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

---

Requirements

Release 8 only supports Python 3.6 or higher.

The only mandatory dependency is MongoDB or PostgreSQL. Everything else is optional.

• Postgres version 9.5 or better
• MongoDB version 3.6 or better (4.0.7 required for full query syntax support)

Installation

To install MongoDB on Debian/Ubuntu run:

$ sudo apt-get install -y mongodb-org
$ mongod

To install MongoDB on CentOS/RHEL run:

$ sudo yum install -y mongodb
$ mongod

To install the Alerta server and client run:

$ pip install alerta-server alerta
$ alertad run

To install the web console run:

$ wget https://github.com/alerta/alerta-webui/releases/latest/download/alerta-webui.tar.gz
$ tar zxvf alerta-webui.tar.gz
$ cd dist
$ python3 -m http.server 8000

>> browse to http://localhost:8000

Docker

Alerta and MongoDB can also run using Docker containers, see alerta/docker-alerta.

Configuration

To configure the alertad server override the default settings in /etc/alertad.conf or using ALERTA_SVR_CONF_FILE environment variable::

$ ALERTA_SVR_CONF_FILE=~/.alertad.conf
$ echo "DEBUG=True" > $ALERTA_SVR_CONF_FILE

Documentation

More information on configuration and other aspects of alerta can be found at http://docs.alerta.io

Development

To run in development mode, listening on port 5000:

$ export FLASK_APP=alerta FLASK_ENV=development
$ pip install -e .
$ flask run

To run in development mode, listening on port 8080, using Postgres and reporting errors to Sentry:

$ export FLASK_APP=alerta FLASK_ENV=development
$ export DATABASE_URL=postgres://localhost:5432/alerta5
$ export SENTRY_DSN=https://8b56098250544fb78b9578d8af2a7e13:fa9d628da9c4459c922293db72a3203f@sentry.io/153768
$ pip install -e .[postgres]
$ flask run --debugger --port 8080 --with-threads --reload

Troubleshooting

Enable debug log output by setting DEBUG=True in the API server configuration:

DEBUG=True

LOG_HANDLERS = ['console','file']
LOG_FORMAT = 'verbose'
LOG_FILE = '$HOME/alertad.log'

It can also be helpful to check the web browser developer console for JavaScript logging, network problems and API error responses.

Tests

To run the all the tests there must be a local Postgres and MongoDB database running. Then run:

$ TOXENV=ALL make test

To just run the Postgres or MongoDB tests run:

$ TOXENV=postgres make test
$ TOXENV=mongodb make test

To run a single test run something like:

$ TOXENV="mongodb -- tests/test_search.py::QueryParserTestCase::test_boolean_operators" make test
$ TOXENV="postgres -- tests/test_queryparser.py::PostgresQueryTestCase::test_boolean_operators" make test

Cloud Deployment

Alerta can be deployed to the cloud easily using Heroku https://github.com/alerta/heroku-api-alerta, AWS EC2 https://github.com/alerta/alerta-cloudformation, or Google Cloud Platform https://github.com/alerta/gcloud-api-alerta
