Monitoring
==========

Monitoring replication setups is important to ensure that your system:

-  Performs optimally

-  Doesn’t run out of disk space

-  Doesn’t encounter other faults that might halt operations

It’s important to have automated monitoring in place to ensure that the
administrator is alerted and can take proactive action when issues
occur. For example, the administrator can be alerted if replication
slots start falling badly behind,

EDB provides Postgres Enterprise Manager (PEM), which supports PGD
starting with version 8.1. See :ref:`Monitoring EDB Postgres Distributed <Node management>`  for more information.

Alternatively, tools or users can make their own calls into information
views and functions provided by the BDR extension. See :ref:`Monitoring through SQL <Monitoring through SQL>`  for
details.

EDB Postgres Distributed also integrates with OpenTelemetry, allowing
you to use an existing reporting setup to follow the state of the EDB
Postgres Distributed cluster. See :ref:`OpenTelemetry integration <OpenTelemetry integration>`  for details.
