Planets9s - How to monitor MongoDB, what to test when upgrading to MySQL 5.7 and more

Posted in:

Welcome to this week’s Planets9s, covering all the latest resources and technologies we create around automation and management of open source database infrastructures.

New webinar on how to monitor MongoDB (if you’re really a MySQL DBA)

As you may know, MongoDB offers many metrics through various status overviews and commands, but which ones really matter to you? How do you trend and alert on them? What is the meaning behind the metrics? In this new webinar on July 12th, we’ll discuss the most important ones and describe them in ordinary plain MySQL DBA language. And we’ll have a look at the (open source) solutions available for MongoDB monitoring and trending, including how to leverage ClusterControl’s MongoDB metrics, dashboards, custom alerting and other features to track and optimize the performance of your system.

This new blog post (and associated whitepaper) show you how.
