Here are Minecraft events you should put in:
Kills a Player
Kills a Mob
Kills an Animal
Crafts Golden or Diamond Material
Finds Golden Stuff or Diamond Stuff
Opens a Chest
Gets Killed
Falls in Lava
Dies to Fall Damage
Places a Water Bucket to Prevent Fall Damage
I feel like dies to fall damage is the same as gets killed, opens a chest could be a major annoyance if it kept recording you opening chests in your base, golden stuff really isn't good enough that I would want to record it, and killing a mob/animal should probably be kept to hostile, if you kept it at all. One thing I would definitely add would be taming stuff, since its not very common and it never hurts to have a record of all the wolves you've tamed, and subsequently accidentally pushed off a cliff.
