System Event Audit Messages

On this page

Note

Available only in MongoDB Enterprise .

Audit Message

The event auditing feature can record events in JSON format. To configure auditing output, see Configure Auditing

The recorded JSON messages have the following syntax:

{
  atype: <String>,
  ts : { "$date": <timestamp> },
  local: { ip: <String>, port: <int> },
  remote: { ip: <String>, port: <int> },
  users : [ { user: <String>, db: <String> }, ... ],
  roles: [ { role: <String>, db: <String> }, ... ],
  param: <document>,
  result: <int>
}
Field Type Description
atype string Action type. See Audit Event Actions, Details, and Results.
ts document Document that contains the date and UTC time of the event, in ISO 8601 format.
local document Document that contains the local ip address and the port number of the running instance.
remote document Document that contains the remote ip address and the port number of the incoming connection associated with the event.
users array Array of user identification documents. Because MongoDB allows a session to log in with different user per database, this array can have more than one user. Each document contains a user field for the username and a db field for the authentication database for that user.
roles array Array of documents that specify the roles granted to the user. Each document contains a role field for the name of the role and a db field for the database associated with the role.
param document Specific details for the event. See Audit Event Actions, Details, and Results.
result integer Error code. See Audit Event Actions, Details, and Results.

Audit Event Actions, Details, and Results

The following table lists for each atype or action type, the associated param details and the result values, if any.
