OCPP Log Generator

The script reads Open Charge Point Protocol (OCPP) packets and outputs their contents to a log file, which can be used for troubleshooting.

There are two modes supported:

ONLINE: This mode continiously captures packets from an interface that should be manually specified. Each TCP packet will be passed through a Python Scapy pipeline engine, which will heuristically identify whether it has a WebSocket payload. If masked, the WebSocket payload will be unmasked, and then saved to a timestamped log file using the Python logging facility.
OFFLINE: Does the same procedure, but reads pcaps instead.

Regardless of the mode, the output logs are generated in the ./output-logs directory (relevant to the logGenerator.py location).

Any input pcaps for the offline mode should be placed in the ./pcaps directory (relevant to the logGenerator.py location).

The OCPP Log Generator must be configured by creating a file named config.ini with the following structure:

[Settings]

OperationMode=OFFLINE
#OperationMode=ONLINE
OfflineFiles=monitor.pcap
CaptureInterface=eth1

OperationMode can be specified as either OFFLINE or ONLINE.
If OperationMode=OFFLINE, then OfflineFiles must also be specified.
One or multiple filenames can be assigned to OfflineFiles, separated by semicolon. For example, OfflineFiles=monitor.pcap or OfflineFiles=monitor1.pcap;monitor2.pcap.
CaptureInterface specified the interface used for capturing packets (only in online mode).
