This audit log contains all the commands ran on the cluster, the account logged, and he source of the connection: Example From user logged into console: Sat Apr 20 2024 09:12:28 -05:00 [kern_audit:info:3000] 8003e80000000740:8003e80000000741 :: Cluster01:console :: localhost:unknown :: Cluster01:admin :: system node run -node node1 -command volume show :: Pending Example from SystemManager: Tue Apr 23 2024 02:33:57 -04:00 [kern_audit:info:3646] 8503ec000033fcbd :: Cluster01:ontapi :: 14.80.109.10:55010 :: Cluster01:admin :: volume-mount :: Success: Example from SSH: Tue Apr 23 2024 09:21:28 -04:00 [kern_audit:info:3646] 8003ec000029102a:8003ec000029102b :: Cluster01:ssh :: 10.10.0.10:51045 :: Cluster01:admin :: Logging in :: Success
