The upcoming OMV6 will help you to keep an overview of what happens on your system. Because of that some more dashboard widgets have been added to visualize the system status.

In OMV6 dashboard widgets are implemented in a declarative style. Drop a YAML file into a special folder, create a new RPC endpoint or use an existing one, run the omv-mkworkbench CLI command to generate the Workbench UI configuration and you’re done.

The code for the Memory and CPU Usage widget looks like:

version: "1.0"
type: dashboard-widget

A datatable widget will look like:

version: "1.0"
type: dashboard-widget

  id: 1dc0ac9a-df14-11ea-8342-6fcac5f2e571
  title: _("File Systems")

    role:
    - admin
  datatable:
    columns:
    - name: _("Device")
      prop: canonicaldevicefile

      sortable: true
    - name: _("Label")
      prop: label
      flexGrow: 1
      sortable: true
      hidden: true
    - name: _("Total")
      prop: size
      flexGrow: 1
      sortable: true
      cellTemplateName: template
      cellTemplateConfig: '{{ size | tobytes | binaryunit | notavailable("-") }}'
    - name: _("Available")
      prop: available
      flexGrow: 1
      sortable: true
      cellTemplateName: template
      cellTemplateConfig: '{{ available | tobytes | binaryunit | notavailable("-") }}'

        get:
          method: enumerateFilesystems
    sorters:
