So you have log management system, and you wonder how will you name logs that arrive at that central system ?
Stuff you posted are commands doing what a human or script instructed them on the box monitored.
Some of them read plain files, others inspect processes or follow links.
More or less standard stuff a user or administrator would do on a system, if allowed by permissions (files/directory permissions, ability to connect to machine etc.)
I'm not sure what kind of best practice advice you require.
Can you specify to more detail perhaps ?
And welcome to the forums
