nuclei 'stats' build : scan events + chart utils

[tarunKoyalwar]

Proposed Changes

• updates default types.Options with payload-concurrency and probe-concurrency (cc: @Ice3man543 , @ShubhamRasal )
• simply put this pr adds all utilities / tools based on experimental scan events => https://github.com/tarunKoyalwar/nuclei-charts
• when nuclei is built with -tags=stats and executed on targets , it will create a directory in current working directory with pattern nuclei-stats-xxxx ,
• this directory can then be passed to scan-charts cmd / utility that visualizes by generating static html using apache e-charts

Usage

step 1) make build-stats -> creates new nuclei-stats binary
step 2) run create binary on target[s]

 ./nuclei-stats -u http://honey.scanme.sh -c 300 -stats 

step 3) make scan-charts -> create new scan-charts binary
step 4) pass newly created directory to scan-charts and it will start a minimal html server which has 4 different types of charts based on logged events from previous scan

$ ./scan-charts -dir nuclei-stats-20240411171731

Note

stats ( aka events) are not logged and the logic related to that is also not present in default build of nuclei , to enable this functionality one needs to pass stats tag when installing or building

go build -tags=stats -o "nuclei-stats" cmd/nuclei/main.go
