Hi @roopeshetty
the main difference between the two screenshot is that the Lens table performs aggregations before showing them on the table, while Discover shows the raw data.
I would suggest to use a Discover panel to show raw documents and Lens tables for aggregated data. While it is still possible to "suggest" a shorter time interval for the table date histogram in Lens, I think in an alert use case this doesn't guarantee any document-level granularity.
