You can use the following commands to work with human-readable logs and structured logs.

`p4 logappend` | If the user log is enabled, write an entry to any structured log file that includes user log events, such as `user.csv`.
`p4 logparse` | Parse a structured log file and return the logged data in tagged format

`p4 logstat` | Report the file size of the journal (`P4JOURNAL`, error log (`P4LOG`), audit log (`P4AUDIT`), or the named structured log file.
