MathLM logs its activity if launched with the “-logfile” flag.

To begin collecting log messages in the file filename, start MathLM from the command line using:

mathlm -logfile filename

Note that you need to have write permissions to the specified file’s directory. The log file will contain messages of the following form:

hostname.domain.com - username [11/Dec/2023:22:01:01] "MathLM 14.0.0 executable launched" "mathlm" -
hostname.domain.com - username [11/Dec/2023:22:01:01] "Verbosity level specified" "1" -
hostname.domain.com - username [11/Dec/2023:22:01:01] "Logging verbosity level specified" "3" -

hostname.domain.com - username [11/Dec/2023:22:01:01] "Binding IPv6 socket" "Success. Socket 16287 taken." -
hostname.domain.com - username [11/Dec/2023:22:01:01] "Binding IPv4 socket" "Success. Socket 16286 taken." -
hostname.domain.com - username [11/Dec/2023:22:01:01] "Hostname" "hostname.domain.com" -


These messages are comprised of the host name, username, a timestamp and the specific message.

The “-loglevel n” flag allows adjusting the level of verbosity from its default value of 3 to any number between 1 (least verbose) and 4 (most verbose). The types of messages logged at each verbosity level are described in detail here.

If necessary, you can customize the log messages’ format.
