Broken Metricbeat dashboards

[inqueue]

Metricbeat 6.0.0-beta1 BC2

The Metricbeat host overview and Metricbeat system overview dashboards are showing error "The request for this panel failed." for several visualizations. The same visualizations load correctly when launched individually or placed in a new dashboard. The issue appears to be something specific to the dashboards.

Dashboards were installed with:

./metricbeat setup --dashboards

I've reproduced this issue

Graph seems to work while editing, it just fails in the dashboard, where I see this error message in the developer console

commons.bundle.js?v=15762:38 Error: [ngRepeat:dupes] Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater: legendData in labels track by legendData.label, Duplicate key: 100% - 100%, Duplicate value: {"label":"100% - 100%"}

Still researching, this may be a kibana issue

Looks like this can be workedaround by simply entering the empty string (just press enter), or * in the search box.

I think what happened was that Kibana changed the format in which the query string is saved. This is in the imported dashboards:

{
  "filter": [
    {
      "query": {
        "query_string": {
          "analyze_wildcard": true,
          "query": "*"
        }
      }
    }
  ]
}

And this is how it looks in a newly created dashboard:

{
  "query": {
    "language": "lucene",
    "query": ""
  },
  "filter": [],
  "highlightAll": true,
  "version": true
}

[tsg]

Closing in favor of elastic/kibana#13181.
