Alert example

prom2teams is a Web server built with Python that receives alert notifications from a previously configured Prometheus Alertmanager instance and forwards it to Microsoft Teams using defined connectors.

Getting Started

Prerequisites

The application has been tested with Prometheus 1.7.1, Python 3.5.0 and pip 9.0.1.

Newer versions of Prometheus/Python/pip should work but could also present issues.

Installing

prom2teams is present on PyPI, so could be installed using pip3:

$ pip3 install prom2teams

Note: Only works since v1.1.1

Usage

# To start the server (a config file path must be provided, log file path, log level and Jinja2 template path are optional arguments):
$ prom2teams --configpath <config file path> [--logfilepath <log file path>] [--loglevel (DEBUG|INFO|WARNING|ERROR|CRITICAL)] [--templatepath <Jinja2 template file path>]

# To show the help message:
$ prom2teams --help

Note: default log level is INFO. Messages are redirected to stdout if no log file path is provided.

Config file

The config file is an INI file and should have the structure described below:

[HTTP Server]
Host: <host ip> # default: 0.0.0.0
Port: <host port> # default: 8089

[Microsoft Teams]
# At least one connector is required here
Connector: <webhook url> 
AnotherConnector: <webhook url>   
...

Configuring Prometheus

The webhook receiver in Prometheus allows configuring a prom2teams server.

The url is formed by the host and port defined in the previous step.

Note: In order to keep compatibility with previous versions, v2.0 keep attending the default connector ("Connector") in the endpoint 0.0.0.0:8089. This will be removed in future versions.

# The prom2teams endpoint to send HTTP POST requests to.
url: 0.0.0.0:8089/v2/<Connector1>

Templating

prom2teams provides a default template built with Jinja2 to render messages in Microsoft Teams. This template could be overrided using the 'templatepath' argument ('--templatepath ') during the application start.

Some fields are considered mandatory when received from Alert Manager. If such a field is not included a default value of 'unknown' is assigned as described below:

Other optional fields are skipped and not included in the Teams message.

Swagger UI

Accessing to <Host>:<Port> (e.g. localhost:8089) in a web browser shows the API documentation.

Swagger UI

Testing

To run the test suite you should type the following:

# After cloning prom2teams :)
$ python3 -m unittest discover tests
