**Pinpoint** is an APM \(Application Performance Management\) tool for large-scale distributed systems written in Java / [PHP](https://github.com/pinpoint-apm/pinpoint-c-agent). Inspired by [Dapper](http://research.google.com/pubs/pub36356.html), Pinpoint provides a solution to help analyze the overall structure of the system and how components within them are interconnected by tracing transactions across distributed applications.
You should definitely check **Pinpoint** out If you want to
* understand your [application topology](want-a-quick-tour/overview.md) at a glance
* monitor your application in _Real-Time_
* gain code-level visibility to every transaction
* install APM Agents without changing a single line of code
* have minimal impact on the performance \(approximately 3% increase in resource usage\)
