Historical Progression

Missing Introspector data

Some graphs are not shown as there is no Fuzz Introspector data available. Please see indexing page for the relevant build logs. Once the build is working additionals graphs will be displayed.

Per Fuzzer Progression

This section shows graphs for the coverage results per fuzz target over the past 30 days. Included are the coverage percentage, total number of lines, covered number of lines, and the number of coverage inputs.
