Github PR Metrics Graphite Exporter

Grafana Example

This exporter converts raw GitHub pull request data to time series. The exported data points represent the number of seconds (⏰ business hours only, Mon-Fri 09:00 - 17:00) elapsed between the creation of the pull request and the merging of the pull request.

The timestamp is the creation time of the PR.

Exposed metrics name: prs.time_to_merge

Usage

$ npm install

# Path to the SQLite db file containing the PR data retrieved from GitHub.
$ export PULL_REQUESTS_DATABASE_PATH=data/example.db

$ npm start

# The generated time series will be written to `stdout`.
# prs.time_to_merge 3450 1554125772
# prs.time_to_merge 935617 1553187544
# ...

If you have docker installed, try make run to explore the metric. The target spins up a Graphite stack and injects some sample data which can be explored through the exposed Graphite UI on localhost:80.
