Azure App Insights show space consuming metrics

Question

I got alerts that my daily 1GB limit app insight data volume is exceeded. How can I figure out what entries are consuming the most space?

The graph under app insights -> Usage and estimated costs shows me a summary, but I can't drill down.

I couldn't find any property of log/trace entries that gives me the size.

• Is there any?
• Which entries are accumulated in the "metric" category?
• Can I somehow get the query, that generates this chart?

or using summarize operator:

or in azure portal -> click on "Metrics" menu for more details:
