Percona Monitoring and Management 2.1.0

Date: November 11, 2019

Percona Monitoring and Management (PMM) is a free and open-source platform for managing and monitoring MySQL, MongoDB, and PostgreSQL performance. You can run PMM in your own environment for maximum security and reliability. It provides thorough time-based analysis for MySQL, MongoDB, and PostgreSQL servers to ensure that your data works as efficiently as possible.

For install instructions, see Installing Percona Monitoring and Management.
