trendlines 0.5.0

Lightweight time-series recording.

Trendlines

A simple, lightweight alternative to Graphite.

What is Trendlines?

Trendlines is a tool for passively collecting and displaying time-based or sequential numeric data. Built on Flask, PeeWee, and Plotly, it provides a simple interface for adding and viewing your metrics.

What can I use it for?

Anything, really. Well, anything that (a) you can assign a number to and (b) might change over time.

Examples include:

• Test coverage per project
• Code quality metrics per commit
• House temperature
• Distance driven per trip
• Distance per fillup (or per charge for the eco-friendly folk)
• How many times the dog barks
• How often some clicks the Big Red Button on your webpage

It's been designed to handle infrequent, variable interval data. Sometimes real-world data just doesn't appear at nice, regular intervals.

Quickstart

Install and run in a development environment using Docker:

docker run -p 5000:80 -d dougthor42/trendlines:latest

Send in some data:

Note: there are simplier ways to do this. Please see the usage documentation for details.

curl -X POST --data '{"metric": "my.metric", "value": 12.234}" \
     --header "Content-Type: application/json" \
     http://localhost:5000/api/v1/data

And then open up a browser and navigate to http://localhost:5000.
