Monitoring DX NetOps Portal Topology Service Health via REST API

Issue/Introduction
Users experience intermittent "Internal Server Error" messages when accessing the Portal -> Inventory -> Topology view in DX NetOps Performance Center (version 25.4.8 or similar). These outages often correlate with issues in the underlying Neo4j graph service, but there is no obvious health-check endpoint in the standard /pc/center/rest documentation to automate monitoring.
Environment
- Product: DX NetOps Performance Management
- Component: Performance Center Portal / Topology Service
- Version: 25.4.x and above
- Operating System: Linux
Cause
DX NetOps Portal does not expose a dedicated public REST API endpoint specifically for monitoring the real-time health or uptime of internal microservices like Neo4j. Status is typically handled by internal background threads rather than a polling API.
Resolution
Monitor the neo4j service status directly on the Topology host. If this service is down, the Topology GUI will fail.
systemctl status neo4j.service
