  title: Liberty Application Restart with Diagnostics
  summary: Restart a Liberty application, capture a server dump, and verify health.
  description: >-
    A WebSphere Liberty troubleshooting flow for an unstable application. The
    workflow reads the target application, restarts it, creates a server dump
    capturing heap and thread diagnostics for later analysis, and then runs the
    MicroProfile Health check to confirm the server is reporting UP. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
