This article describes how to monitor Concerto.

You can monitor the following components of Concerto from the Concerto UI:

Concerto nodes—Monitor node reachability and current node status.
Concerto database—Monitor the status of the Concerto database. To provide distribution and high availability for the database across nodes, Concerto uses the PostgreSQL distributed database system and the Patroni tool. Patroni works in conjunction with Apache ZooKeeper to provide database node monitoring and automatic failover services.
Service processes—Monitor the state of Concerto service processes, such as the GlusterFS distributed file system and Apache ZooKeeper.
