Affected visualizations:

• Uptime [Metrics Apache]
• Total accesses [Metrics Apache]
• Total egress [Metrics Apache]

Two problems:

1. The empty index_pattern makes them fall back to the default data view.
   -> [TSVB] Technical debt - remove default_index_pattern and default_timefield from model kibana#95925
2. The empty interval may result in fixed_interval": "10s", which is shorter than the default 30s polling interval.
   -> https://github.com/elastic/integrations/blob/main/packages/apache/data_stream/status/manifest.yml#LL12C18-L12C21

Workarounds:

1. Make metrics-* data view default from Kibana > Stack Management > Data Views.
2. Set shorter period such as 10s through Agent policy.

How to fix:

Set metrics-* to index_pattern and >=1m to interval explicitly. Preferably explicit @timestamp to time_field as well.
