Isilon OneFS: List of Isilon Audit Payload Values

The following is a list of possible Isilon values that can be seen in the raw outputs of isi_audit results.

This listing is not version-specific. Some of these codes only exist on certain versions of OneFS. Later versions of OneFS have expanded options; this article lists all audit payloads across all versions. This list is intended to be a reference in reviewing individual audit events in general.

Audit can monitor and track the actions of accounts connected to the OneFS file system on protocols such as SMB and NFS.

The actions recorded in their raw form appear like this (some variance occurs between versions and eras of OneFS):

• protocol: String of the protocol the action occurred under. Usually one of the following in OneFS 7.2 and later: "CIFS" (for SMB1); "SMB2"; "NFS" (for NFSv3); "NFS4"; "HDFS"
• relativePath: UNC name of the file (or dir) as accessed by the client
• rootInode: Integer of the inode of the directory where the partialPath is
• serverIp: The IP address of the server at which the event was recorded
• server: The Server name where the event occurred. Server IP for NFS
• share: The Share on the server; the Export name for NFS
• timeStamp: The time at which the file operation occurred (cluster local time). It is a 64-bit value, where the high 32 bits represent the time and the lower 32 bits represent the microseconds (Format: 0x1234abcd1234abcd)
• type: File, Directory, etc.
• userID: Integer of the UID of the user performing the action (OneFS 7.2 and later)
