Downloading the system state for a cluster or node

Version:

Only available versions of this content are shown in the dropdown

To help troubleshooting, download the system state data for the current state or a previously saved state into a JSON file. You can download the system state data for a single node or for the whole cluster. For example, you can compare the state of the system over time to determine what might have changed on the system that caused the problem.

To access the Cluster Management landing page and download the system state JSON file, you must have the PegaRULES:SysOpsObserver role.

Cluster specific data is saved once a day. Node-specific data is saved when a node starts up. Once downloaded, you can convert the JSON file to a readable format using a tool such as JSON Editor Online and compare two files using a tool such as JSON Diff.

To use a third-party tool to access the current system state, use a REST API. For more details, see Downloading the system state by using a REST API.
