locust-influxdb-listener

Package that uses locust 'event' hooks to push locust related events to an influxDB database.

Prerequisites

This package requires locustIO v1.5.0 or greater.

Installation

Install using your favorite package installer:

pip install locust-influxdb-listener
# or
easy_install locust-influxdb-listener

Usage

Import the library and use the event.init hook to register the listener.

...
from locust_influxdb_listener import InfluxDBListener, InfluxDBSettings

@events.init.add_listener
def on_locust_init(environment, **_kwargs):
    """
    Hook event that enables starting an influxdb connection
    """
    # this settings matches the given docker-compose file
    influxDBSettings = InfluxDBSettings(
        host = 'localhost',
        port = '8086',
        user = 'admin',
        pwd = 'pass',
        database = 'test-project'
        
        # optional global tags to be added to each metric sent to influxdb
        additional_tags = {
            'environment': 'test',
            'some_other_tag': 'tag_value',
        }
    )
    # start listerner with the given configuration
    InfluxDBListener(env=environment, influxDbSettings=influxDBSettings)
...

Example

You can find a working example under the examples folder

InfluxDB with Grafana

We have included a working example docker-compose.yml file that can be used to spin a reporting setup in case you don't have one.

(Make sure you have docker and docker-compose installed and just run:

docker-compose up

Configuration

Once grafana is running (by default on port: 3000) https://localhost:3000 , you need to:

  • Connect to influxdb as the datasource:

  • Import a new dashboard. We have provided a custom dashboard for you locust-grafana-dashboard.json that just works out of the box with the locust-events that the listener will emmit.
