Winlogbeat doesn't create custom index-patterns but Elasticsearch does create custom index names, so everything is broken

Let’s say I want to have winlogbeat and metricbeat in windows machines for two areas of my company… so I created two spaces in Kibana: “foo” and “bar”.

I want to have different indices for each space.. so, instead of winlogbeat-7.9.1-* , I want to have it as foo-winlogbeat-7.9.1-* and bar-winlogbeat-7.9.1-* and the same for the metricbeat case…
I achieve that in metricbeat, but winlogbeat does't create the correct index-pattern, so the visualizations are pointing to the default index (winlogbeat-) instead the one I need (foo-winlogbeat-).

My guess is something is wrong/different in winlogbeat vs metricbeat about his point.
the relevant configuration in metricbeat was:

setup.template.pattern: "foo-metricbeat-*"
setup.ilm.rollover_alias: "foo-metricbeat"
setup.dashboards.enabled: true
setup.dashboards.index: "foo-metricbeat-*"
setup.kibana:
host: "1.1.1.1:5601"
space.id: "foo"
output.elasticsearch:
hosts: ["1.1.1.1:9200"]
protocol: "https"
ssl.certificate_authorities: ['C:\certs\ca\ca.crt']
username: "elastic"
password: "password"
output.elasticsearch.index: "foo-metricbeat-%{[agent.version]}-%{+yyyy.MM.dd}"

With pretty much the same configuration (in that section) with winlogbeat, doesn't create the correct index-pattern nor visualizations. It just ignores this part (but in Elasticsearch the index is created as foo-winlogbeat*)

Hmmm, this is strange. The code that handles index pattern creation is common across all Beats. Can you try running winlogbeat setup and see if that creates the correct index pattern?

[syunusic (Sacha Yunusic)]

What I run is "winlogbeat setup -e -c winlogbeat.yml" and "metricbeat setup -e -c metricbeat.yml". When I ran metricbeat's, it creates the correct index (foo-metricbeat-* ) in ES, the correct index pattern in Kibana (foo-metricbeat-* ), and all visualizations points to this index patterns.

When I do the same but in winlogbeat, it creates the correct index, installs the correct index template, correct mappings... but incorrect index pattern (it says just winlogbeat-* instead of foo-winlogbeat-*).

The workaround I made (thanks to a suggestion), is to create the my custom part of the name as a suffix instead of a prefix, so, even when the index pattern is wrong, it will work anyways because it will take winlogbeat-* as a correct pattern, because my index is contained in that pattern (metricbeat-foo in this case).

Still... I think this should be fixed.
