Understanding debug logs for modules

We have set the following debug to check how our policies apply to traffic:

dia deb info debug output:                   enable console output:                 disable debug timestamp:                enable sysinit output:                 disabled flow-filter client_ip:          flow-filter flow-detail:        0 flow-filter http-detail:        0 flow-filter module-detail:      1 flow-filter session-detail:     0 flow-trace:                     1 writedisk:                      0 CLI debug level:                1

We have also enabled module-detail for all modules:

dia deb flow filter module-detail module all

On the debug output we see the following:

Module name:x_forworded_for, Execution:4, Process error:0, Action:ACCEPT Module name:known_engine, Execution:4, Process error:-1, Action:ACCEPT Module name:geo_block, Execution:4, Process error:0, Action:ACCEPT Module name:websocket_security, Execution:3, Process error:0, Action:ACCEPT Module name:hsts_header, Execution:4, Process error:5, Action:ACCEPT Module name:allow_method, Execution:4, Process error:0, Action:ACCEPT Module name:real_browser_enforcement, Execution:3, Process error:2, Action:ACCEPT Module name:session_management, Execution:4, Process error:0, Action:ACCEPT Module name:global_white_list, Execution:4, Process error:0, Action:ACCEPT Module name:global_white_list, Execution:4, Process error:0, Action:ACCEPT Module name:url_access, Execution:4, Process error:7, Action:ACCEPT Module name:file_security, Execution:3, Process error:0, Action:ACCEPT Module name:chunk_decode, Execution:3, Process error:4, Action:ACCEPT Module name:file_uncompress, Execution:3, Process error:0, Action:ACCEPT Module name:file_uncompress, Execution:3, Process error:0, Action:ACCEPT Module name:csrf_check, Execution:4, Process error:0, Action:ACCEPT Module name:mitb_check, Execution:4, Process error:0, Action:CACCEPT Module name:xml_validation, Execution:3, Process error:4, Action:ACCEPT Module name:json_protection, Execution:1, Process error:3, Action:ACCEPT Module name:signature_detection, Execution:4, Process error:7, Action:ACCEPT Module name:custom_access, Execution:4, Process error:6, Action:ACCEPT Module name:user_tracking, Execution:3, Process error:2, Action:ACCEPT Module name:url_rewriting, Execution:4, Process error:0, Action:ACCEPT Module name:file_compress, Execution:3, Process error:-1, Action:ACCEPT Module name:http_header_security, Execution:3, Process error:0, Action:ACCEPT Module name:client_cert_forword, Execution:3, Process error:3, Action:ACCEPT Module name:file_security, Execution:3, Process error:0, Action:FOLLOWUP_FAILE Module name:chunk_decode, Execution:3, Process error:4, Action:FOLLOWUP_FAILE Module name:file_uncompress, Execution:3, Process error:0, Action:FOLLOWUP_FAILE Module name:file_uncompress, Execution:3, Process error:0, Action:FOLLOWUP_FAILE Module name:csrf_check, Execution:3, Process error:7, Action:FOLLOWUP_FAILE Module name:mitb_check, Execution:4, Process error:0, Action:FOLLOWUP_FAILE Module name:xml_validation, Execution:3, Process error:6, Action:FOLLOWUP_FAILE Module name:json_protection, Execution:3, Process error:6, Action:FOLLOWUP_FAILE Module name:signature_detection, Execution:2, Process error:28, Action:ACCEPT Module name:custom_access, Execution:4, Process error:6, Action:ACCEPT Module name:user_tracking, Execution:3, Process error:0, Action:FOLLOWUP_FAILE Module name:url_rewriting, Execution:3, Process error:24, Action:FOLLOWUP_FAILE Module name:machine_learning, Execution:3, Process error:0, Action:FOLLOWUP_FAILE Module name:file_compress, Execution:3, Process error:-1, Action:FOLLOWUP_FAILE Module name:file_compress, Execution:3, Process error:0, Action:FOLLOWUP_FAILE Module name:machine_learning, Execution:2, Process error:2, Action:ACCEPT

Any idea on how we should interpret Execution #, Process error # and Action? Is this documented?
