—diff

Compares log patterns between a baseline and a comparison period. Highlights messages that appear more or less frequently than expected — useful for detecting regressions after a deploy or spotting new error patterns.

Syntax

--diff:<baseline>
--diff:<baseline>:<comparison>

Time references use hyphenated natural language:

Examples

--diff:yesterday
--diff:2-days-ago:yesterday
level:error --diff:yesterday

Notes

• When only baseline is given, it compares the baseline period against the current active time range
• When both are given, baseline vs comparison are compared directly
• Executes on submit
• Scope: advanced filter bar
