Pinba accumulates data in a set of read-only MySQL tables, consisting of two types:

1) Raw data tables: These tables are used to generate custom reports. Accessing raw data is relatively slow if there are a large number of records with no index except for primary keys.

2) Reports: These are already aggregated data that updates on-the-fly as new request data arrives.

The Pinba working stack comprises two parts: the Pinba engine and the PHP extension. The Pinba Engine acts as a pluggable storage engine for MySQL or MariaDB, while clients such as the PHP Pinba Extension and the Nginx Pinba Module feed data into it. The engine itself provides access to reports and raw data. There is a GUI available called “Pinboard”.

Advantages

1) Powerful
2) Provides live metrics in production with no impact on performance
3) Helps detect bottlenecks
4) Used to find bugs (e.g., excessive backend usage in certain routes)
5) Enables the creation of graphs and integration with alerting systems to detect regressions after a release.
