audit log explanation

[MichielvM]

Hi, I've been browsing the audit log.
Can somenone tell me exactly what these messages mean?

User submitted a command to the subsystem
User authenticated against Nagios XI credentials

[lmiltchev]

You can see if the nagiosadmin user (or a different user) logged in XI (and from what IP address), and submitted a command to the subsystem (enabling/disabling notifications, acknowledgement, etc.).
