System node data instances in on-premises systems

Updated on May 11, 2022

In a multi-node cluster, complete this optional form to supply an HTML description of each node in your multi-node system.

A system node instance is automatically created each time a new server joins a system. The key is a system-generated hexadecimal hash value, the node ID. To view the system nodes, in the navigation panel of Dev Studio, click RecordsSysAdminSystem Node. To view details for a node, click a node.

To improve the clarity of the log-on screen, alert log, and other listings, enter a Short Description that uniquely identifies this node. Chose text that is more meaningful to system administrators than the hash node ID value.

Where referenced

The Node Description you enter appears on the Systems Nodes Detail report, which lists all nodes that participated in your system (by connecting to the PegaRULES database) during the last 30 days.

Log-in form footer

The Short Description appears in the footer of the log-in form, in the alert log, and in other listings.


Use the Records Explorer to list the system node data instances on your system.


The Data-Admin-Nodes class contains system node data instances. They are part of the SysAdmin category.
