Professional database monitoring software can monitor a wide range of NoSQL databases, including MongoDB, Redis, Cassandra, and Elasticsearch. It can also monitor applications that interact with NoSQL databases, such as web applications and business intelligence applications. This visibility can be used to identify and troubleshoot performance problems, optimize database performance, and ensure that applications are running smoothly. As the central point of contact for information about the company’s database management systems, DBAs must keep up to date on the latest versions and capabilities of each DBMS.
