Amazon DocumentDB is an AWS-managed document database service that supports MongoDB, the well known open source database. As a managed service, AWS automatically handles database management tasks, autoscales database clusters, and backs up your data to S3. DocumentDB implements the Apache 2.0 open source MongoDB 3.6 API, making it easy to migrate your existing MongoDB workloads to DocumentDB.

Amazon RDS allows you to store your application data in databases without having to actually manage the servers the databases are hosted on. It also allows you to easily set up read replicas and take snapshots of your database. However, since it’s a managed service, you have less visibility with traditional monitoring tools. As such, it becomes even more important to take advantage of the available monitoring tools in AWS.

Redis (which stands for REmote DIctionary Server) is an open source, in-memory datastore, often used as a database, cache or message broker. It can store and manipulate high-level data types like lists, maps, sets, and sorted sets. Because Redis accepts keys in a wide range of formats, operations can be executed on the server, which reduces the client’s workload. It holds its database entirely in memory, only using the disk for persistence.

So you’ve got a ClickHouse DBMS, and you’re looking for a tool to monitor it. You’ve come to the right place. In this blog post (which is part 2 of a three-part series on ClickHouse monitoring), we’ll identify and discuss the various ClickHouse monitoring tools available today.
