Description of problem:
As elastic recommend we should remove all _source for metrics index.
Currently only fields under collectd namespace are removed.

Version-Release number of selected component (if applicable):
3.6.1

How reproducible:
100%

Steps to Reproduce:
1.Send metrics data from oVirt to the openshift setup.

The source is not saved for the collectd fields.

Has something changed?

_source and _all fields should all be disabled for the the records in the indexes of project.ovirt-metrics* should be removed.

As recommended by https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-source-field.html

Currently only collectd namespaces have source disabled.
The fields are enriched with pipline , kubernetes and ovirt metadata fields.
The _source and _all fields should be disabled for them as well.

For testing, You should not see any metrics related data in the discovery tab.
Only an option to create graphs in the visualize tab and dashboards.

See attachement with the fields that are still have _source field.

Can we raise priority on this? 

This one is blocking verification process and QA automation regarding integration of oVirt and Viaq and is required by RHV-QA.

What is it blocking?

see BZ#1494190 I don't think it is a good way to remove this record if it will cause data not being populated in Discovery tab. If it's a requirement from the elasticsearch side, we should find another way to query the data in Discovery tab.

@lvlcek - do you know of a good query, using curl and the query api, that can be used to determine if the collectd stats are being stored in Elasticsearch?

Same as in other metrics solutions, like prometheus and graphite, the metrics samples are not required to be viewed per sample.

We should find a solution for qa testing metrics. But, we should not save the source and all fields.

Probably the best way would be pre-defined dashboards.
