CAN file and SFTP loggers

The CAN File Logger and the CAN SFTP Logger record native CAN bus messages to a file. The CAN File Logger stores the file on the local file system of the machine running Profinity. The CAN SFTP Logger transmits it to a remote Secure Shell (SSH) File Transfer Protocol (SFTP) server. Each is added to a Profile as its own component under Loggers and is included in every edition. Profinity can also log and replay messages from a CAN bus network.

The CAN File Logger records CAN bus messages to log files on the local file system, and the CAN SFTP Logger transmits them to an SFTP server

Both loggers have Auto Connect, which is on by default, so a logger begins logging when the Profile loads. Refer to Connections and reconnecting for how it behaves. They record the bus, so they do not use tag collections.

Both loggers have these settings:

Update Interval (Seconds) sets the seconds between background updates. It defaults to 10 and accepts values from 1 to 86400.
File Format chooses the layout of the text file, which always uses a .txt extension. Prohelion, the default, writes a line for every packet with a Sent or Received column. Tritium writes the same fields without that column.

The CAN File Logger has no destination setting. It creates its files under the Profinity CAN bus log directory (can_bus_logs/), in a folder named after the Profile and the component. Refer to the artefacts directory for where that directory sits on each platform. The CAN SFTP Logger needs the remote server settings described in File logger rotation, archive, and SFTP settings, which also covers rotating, archiving, and compressing the log files.

Download the logged files

Once a log file has been created, select the link on the Logger Dashboard to download it from Profinity. A CAN File Logger shows this link as FILE LOGS REPOSITORY.
