How to Monitor Cached Datasets in Flash?¶

Monitoring cached datasets in Flash is essential for tracking performance and resource usage. To enable monitoring, the ingress attribute must be included in the Flash Service manifest file, as shown below:

service:
  servicePort: ${{8080}}
  servicePorts:
  - name: ${{backup}}
    servicePort: ${{5433}}
  ingress:
    enabled: ${{true}}
    stripPath: ${{false}}
    path: ${{/flash/public:flash-test-6}}
    noAuthentication: ${{true}}
  replicas: ${{1}}
  logLevel: ${{info}}
  compute: ${{runnable-default}}
  envs:
    APP_BASE_PATH: ${{'dataos-basepath'}}
    FLASH_BASE_PATH: ${{/flash/public:flash-test-6}}
  resources:
    requests:
      cpu: ${{500m}}
      memory: ${{512Mi}}
    limits:
      cpu: ${{1000m}}
      memory: ${{1024Mi}}

The ingress attribute allows access to the Flash web app, which enables monitoring of the cached datasets.
