Monitoring replication setups is important to ensure that your system performs optimally and does not run out of disk space or encounter other faults that may halt operations.
It is important to have automated monitoring in place to ensure that if, for example, replication slots start falling badly behind, the administrator is alerted and can take proactive action.
EDB provides Postgres Enterprise Manager (PEM), which supports BDR from version 8.1. See Monitoring EDB Postgres Distributed for more information.
Alternatively, tools or users can make their own calls into information views and functions provided by the BDR extension. See Monitoring through SQL for detailed description.
EDB Postgres Distributed also integrates with OpenTelemetry, allowing you to use existing reporting setup to follow the state of the EDB Postgres Distributed cluster. See the OpenTelemetry integration chapter for details.
