Alerta Release 6.6

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

Python 2.7 support is EOL

Starting with Release 6.0 only Python 3.5+ is supported. Release 5.2 was the last to support Python 2.7 and feature enhancements for this release ended on August 31, 2018. Only critical bug fixes will be backported to Release 5.2.

Requirements

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

• Postgres version 9.5 or better
• MongoDB version 3.x

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 -O alerta-web.tgz https://github.com/alerta/angular-alerta-webui/tarball/master
$ tar zxvf alerta-web.tgz
$ cd alerta-angular-alerta-webui-*/app
$ python -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 .
$ flask run --debugger --port 8080 --with-threads --reload

Troubleshooting

Problems following a direct upgrade from versions 4.x to 5.x could be related to the flattening of the directory structure for the app. An example app.wsgi file which works for both release 4 and 5 is as follows:

#!/usr/bin/env python

try:
    from alerta import app  # alerta >= 5.0
except Exception:
    from alerta.app import app  # alerta < 5.0

Tests

To run the tests using a local Postgres database run:

$ pip install -r requirements.txt
$ pip install -e .
$ createdb test5
$ ALERTA_SVR_CONF_FILE= DATABASE_URL=postgres:///test5 nosetests

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
