Prometheus Lite

History

Prometheus was developed at SoundCloud starting in 2012, when the company discovered that its existing metrics and monitoring tools. Specifically, they identified needs that Prometheus was built to meet including: a multi-dimensional data model, operational simplicity, scalable data collection, and a powerful query language, all in a single tool. The project was open-source from the beginning and began to be used by Boxever and Docker users as well, despite not being explicitly announced. Prometheus was inspired by the monitoring tool Borgmon used at Google

Code Quality

My overall opinion:

• Code package names are good
• Pointers of an Object Field is returned in some Functions. This is not a good practice. Feels kind of like C.
• Parser is simple
• PromQL is simple
• Need to revisit histogram and vectors.
• Need to revisit TSDB
• Need to revisit Fanout storage and distributed aspect of it.

Core Features

• Custom Parse (good starting point for tiny parser)
• PromQL using AST
• Storage Adapter Layer + Fanout
• TSDB
• Rules Manager and Notifier
• Web UI + REST API

How to run

Right now, we have a basic test in here

It computes 6/3 and returns 2.
