I am building a custom app in WordPress, so I need some means of logging my events. I searched and found this plugin - http://wordpress.org/extend/plugins/wp-logs/ which looks very convenient to use. It uses database to store logs and can display them in the backend itself.
Another option for me is to learn WP filesystem (something which I haven't tried yet) and use it to write logs to file on disk. What do you think would be best considering the tradeoff between performance & convenience?
Database write is equal to
I/O write + some extra work. Thoughts?
