Update

It was tried to fix in this PR #2587.
This fix was tested on the dev environment. But in prod in some cases, this fix caused that the statics never load.
That's why the PR was reverted.

Update

Searching deeper, I found the reason why the prop resultState in metrics.tsx causing several request calls.

• The component Metrics is a child of the component wzVisualize, and the last one is sending his prop resultState.

• The component wzVisaulize is used as directive by the template dashboard and this is sending the global variable resultState

• This global variable is set by the controller kibana-discovery.ts through a chain of watchers and observers.

But the problem is that this handler is setting resultState as 'loading' then as 'ready' two times when the controller loads.

This happens because the state of the filters is set two times when FilterManager is called.
The methods from the class FireManager are merging the provided filters and if there are changes, they fire the update events. .

The first time is here

With this data

{
  $state:
  {
    isImplicit: true,
    store: "appState"
  },
  meta:
  {
    alias: null,
    disabled: false,
    index: "wazuh-alerts-*",
    key: "cluster.name",
    negate: false,
    params: {query: "wazuh"},
    removable: false,
    type: "phrase",
    value: formatter => {…}
  },
  query: { match: { cluster.name: {query: "wazuh", type: "phrase"}}}
}

But the method setAppFilters is removing the prop $state.isImplicit

That is why this prop is set againg here

Provoking the second update of the resultState
