Reportes de Moodle - Columna Action

Hola a todos!

Me gustaría saber si existe alguna documentación o glosario que explica cada "Action" que aparece en el reporte de actividad. Por ejemplo, si realizo una consulta SQL en la tabla mdl_logs:

select action from mdl_log group by action

Obtengo:

Me gustaría saber que significa esa columna 'action'. Por ejemplo, qué representa 'course delete mod'.

Ya que debo preparar un informe a partir de ese reporte y los nombres de las acciones no son muy explicativas.

Muchas gracias por la ayuda.

Saludos cordiales,

Angel
