Prometheus exporter for Gradle Enterprise Server

Exporter gets json metrics from Gradle Server endpoint, converts it to Prometheus format and exposes at /metrics.

Usage

Multiple installation scenarios are provided.

Docker

Don't forget to provide a file ./urls.txt with urls. Then run:

PORT=8080 ; docker run -it --rm --name gradle-server-exporter \
  -p ${PORT}:${PORT} \
  -v "$(pwd)/":"/app/" \
  -e APP_FILE_PATH=/app/urls.txt \
  -e APP_PORT=${PORT} \
  -e APP_CHECK_INTERVAL=60 \
  -e LOG_LEVEL=DEBUG \
  bissquit/gradle-server-exporter:latest

Docker-compose

For testing purposes or for quick review you may use Docker Compose:

docker-compose up -d --build

k8s

Use k8s-handle to deploy exporter to k8s environment:

cd kubernetes

k8s-handle apply -s env-name

Render templates without deployment:

k8s-handle render -s env-name

Help

Exporter looks for the file contains url(s) to your Gradle Enterprise Server(s). Each line is well-formatted url. You may pass options both via command line arguments or environment variables:

Command line argument	Environment variable	Description
-h, --help	-	show help message
-f, --file	APP_FILE_PATH	Absolute path to file. Each line is url link (default: Empty string)
-p, --port	APP_PORT	Port to be listened (default: 8080)
-t, --time	APP_CHECK_INTERVAL	Default time range in seconds to check metrics (default: 60)
-	LOG_LEVEL	Log level based on Python logging module. expected values: DEBUG, INFO, WARNING, ERROR, CRITICAL (default: INFO)

Dev environment

Setup environment is quite simple:

make env
make test

Note: tox will install his own environments. You may add it as interpreter in your IDE - ./tox/py39/bin/python

To use Python venv execute the following commands:

mkdir venv
python3 -m venv venv
. venv/bin/activate

make env
make test

To deactivate venv from current shell session run:

deactivate

How to start

make start

Fake GE server

To test exporter locally without real GE servers you may run a fake GE server:

python3 fake_ge_server.py
