Percona Monitoring and Management (PMM)

Databases work great when fresh and clean but over the years you seem to encounter more and more performance issues. Over-enthusiastic developers brimming with confidence can quickly overload tables with indexes or make changes without thinking about scenarios outside their ticket. Business growth can lead to server strain if you aren't monitoring your infra vigilantly. Queries that once worked well can suffer over time and you need a good tool to dig in to the data. PMM is excellent for these kinds of use-cases.

I initially found the vast quantity of data presented to be overwhelming, but that is where I needed to raise my knowledge to understand the DB internals better. If you feel you don't know enough about your database performance the dashboards will keep you busy for a while. The Query Analytics tool may also be insightful. My only gripe is I wish there was more documentation on explaining some of the data for less experienced MySQL users.

I suggest you try [Percona Monitoring and Management (PMM)] at least once. Afterward, it will make you feel relaxed. It really works and gives you more than your expectations. It is equipped with multiple latest and advanced tools that will fully satisfy you. So obviously there will be no need to concern other devices. It is an excellent data management solution and also it is the best monitoring device than any other.

If you're looking for an open-source and free monitoring solution for MySQL, MonogoDB, or Postgres, Percona Monitoring and Management (PMM) is right choice. The metrics plotted helped in doing RCAs for many issues and also assist in identifying trends. Query Analytics enables you to ensure database queries are monitored for optimal performance.
