Percona Monitoring and Management (PMM) is an open source database observability, monitoring, and management tool. It allows database users to observe the health of their systems, explore new patterns in database behavior, quickly troubleshoot issues, and perform database management operations no matter where they are located - on-premises or in the cloud. PMM insights help catch and fix database issues before they start affecting end-users, enabling Developers, DBAs & SREs to focus on important projects instead of spending most of their time hunting down the root cause of the database performance degradation or downtime incidents.
