Monitoring an xDB Replication Cluster¶
Before configuring PEM to retrieve statistics from an Advanced Server or PostgreSQL database that is part of an xDB replication scenario, you must manually install and configure xDB Replication. For more information about xDB replication solutions and documentation, please visit the EDB website at:
The PEM xDB Replication probe monitors lag data for clusters that use xDB multi-primary or single-primary replication that have a publication database that is an EDB Postgres Advanced Server or PostgreSQL database. Please note that if you have configured replication between other proprietary database hosts (i.e. Oracle or SQL Server) and Advanced Server or PostgreSQL, the probe cannot return lag information.
By default, the
xDB Replication probe is disabled. To enable the
xDB Replication probe, right click on the name of
the server, and select
Connect from the context menu; if prompted,
provide authentication information. After connecting, expand the server
node of the tree control, and highlight the name of the replicated
database. Then, select
Manage Probes... from the
Use fields on the

Noto modify the Minutes and Seconds between probe executions.
Enabled?slider to instruct PEM to execute the xDB Replication probe.
Defaultslider in the
Data Retentionfield to No to modify the number of days that PEM will store the information retrieved by the probe.
After enabling the probe, you can use the metrics returned to create custom charts and dashboards in the PEM client.
