Configuration

september:
  dashboard:
    enabled: true
    base-path: /monitor
    title: Acme Monitor
    logo-path: /september/logo.png
    cache-admin-enabled: false

Property	Default	Meaning
september.dashboard.enabled	true	Set false to disable the UI completely
september.dashboard.base-path	/monitor	Path prefix on the host port
september.dashboard.title	September	Top-bar / document title
september.dashboard.logo-path	/september/logo.png	Logo URL (starter static or host override)
september.dashboard.cache-admin-enabled	false	Optional localhost-only cache admin

Static assets live under /september/**. Templates load from the starter JAR (classpath:/templates/september/).

Do not spring.config.import large data YAML files just to browse /env.

Host Actuator settings

The starter does not change Actuator exposure. Suggested local defaults:

management:
  endpoints:
    access:
      default: unrestricted
    web:
      exposure:
        include: health,info,metrics,env,configprops,beans,caches,mappings
  endpoint:
    loggers:
      enabled: false
    shutdown:
      enabled: false
    health:
      show-details: always
    env:
      show-values: never

Dangerous endpoints (shutdown, heapdump, env with show-values: always) stay a host responsibility. Do not expose the dashboard unauthenticated in production.

Screens

• Endpoints — discovery from /actuator _links.
• Metrics — name + unit only, live type=search filter. Detail pages add EN/TR copy, Safe/Caution/Danger bands, and formatted measurements.
• Endpoint explorer — structured tables for beans, health, env, configprops, caches, and more.

Security notes

• Intended for local / dev. Production: authenticate both /monitor/** and /actuator/**.
• Cache admin (when enabled) is localhost-only.
• The starter never enables shutdown or heap dumps by itself.
