Alerta Release 7.0
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
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 3.2 or better
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 tests using a local Postgres database run:
$ pip install -r requirements.txt
$ pip install -e .[postgres]
$ createdb test5
$ ALERTA_SVR_CONF_FILE= DATABASE_URL=postgres:///test5 pytest
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
