Configure Auditing

    Couchbase Server event auditing can be configured, per node.

    HTTP methods and URIs

    GET /settings/audit
    POST /settings/audit
    GET /settings/audit/descriptors


    The GET and POST methods used with the /settings/audit URI respectively read and write the configuration of Couchbase-Server event auditing. This includes the enablement and disablement of auditing, the establishment of an audit-log location, the specification of the time-period on completion of which the log file is to be rotated, the specification of the maximum size at which the log file is to be rotated, and the retrieval of current settings.

    The GET method used with the /settings/audit/descriptors URI returns a document that lists filterable audit events; providing an id, name, module, and description for each. The id can be used in interpreting the output from POST /settings/audit, and in determining input-values for GET /settings/audit. A filterable event is an event that can be individually disabled, even when event-auditing for the node is enabled. Events that are not filterable are not included in the list returned by GET /settings/audit/descriptors.

    Curl Syntax

    curl -X GET -u Administrator:password http://<host>:<port>/settings/audit
    curl -X POST -u Administrator:password http://<host>:<port>/settings/audit
      -d auditdEnabled=[ true | false ]
      -d logPath=[ pathname ]
      -d rotateInterval=[ integer ]
      -d rotateSize=[ integer ]
      -d disabled=[ *{ event-id }, ]
      -d disabledusers=[ *{ local-user | external-user | internal-user }, ]
    curl -X GET -u Administrator:password

    The parameters for the POST method are all optional, and are as follows:

    • The auditdEnabled parameter takes a value of true or false, and thereby either enables or disables auditing on the node. Other values can still be configured, even if auditdEnabled is set to false. When auditing is enabled, all non-filterable events are audited; and none can be individually disabled.

    • The logPath parameter specifies the pathname of the directory to which the audit.log file is written.

    • The rotateInterval parameter specifies the maximum time-period that is to elapse between log-rotations. Its value must be a number of seconds, in the range of 900 (15 minutes) to 604800 (7 days), inclusive.

    • The rotateSize parameter specifes the maximum size to which the audit.log file is permitted to grow, before being rotated. Its value must be a number of bytes, in the range of 0 to 524288000 (500 MB), inclusive.

    • The disabled parameter indicates which individual filterable events are disabled. Its value must be one or more filterable-event ids, specified as a comma-separated list, without spaces. Filterable-event ids can be retrieved by means of the GET /settings/audit/descriptors method and URI.

    • The disabledUsers parameter disables filterable-event auditing on a per user basis. Its value must be a list of users, specified as a comma-separated list, with no spaces. Each user may be:

      • A local user, specified in the form localusername/local.

      • An external user, specified in the form externalusername/external.

      • An internal user, specified in the form @internalusername/local.

        Available internal users are @eventing, @cbq-engine, @ns_server, @index, @projector, @goxdcr, @fts, and @cbas. Internal users can only be specified on Couchbase Server Version 6.0.3 and later.

        If auditdEnabled is true, and one or more users are specified as the value of disabledUsers, only filterable events are ignored for those users: non-filterable events continue to be audited.


    For each method and URI, success gives 200 OK. A malformed URI gives 400 Object Not Found. Failure to authenticate gives 401 Unauthorized.

    Returned-Object Contents

    The GET /settings/audit/descriptors method and URI return a document containing a list of filterable audit events. For each event, the following are provided:

    • id: An integer, such as 20489, which is the identifier for the event.

    • name: A string, which is the name of the event. For example, "document read".

    • module: A string, specifying the system-module within which the event was generated. For example, "memcached".

    • description: A string, providing a description of the event. For example, "Document was read".

    The GET /setttings/audit method and URI return an object that contains the following:

    • disabled: An array of event-ids, each of which corresponds to an event currently disabled.

    • uid: An identifier for system use, corresponding to the current state of the audit-configuration.

    • auditEnabled: A boolean value, indicating whether or not auditing is enabled on the node.

    • disabledusers: An array, each of whose members is a currently disabled user. Each member is an object of two elements, which are the name of the disabled user and their domain.

    • logPath: The current value of the pathname to which the audit.log file is being written.

    • rotateInterval: An integer that is the number of seconds in the maximum time-period on whose elapse the log file is rotated.

    • rotateSize: An integer that is the number of bytes that is the maximum size to which the audit.log file can grow before being rotated.


    The following examples demonstrate how the auditing REST API can be used.

    List Auditable Events

    In the following example, the current list of filterable events is requested. Note that the output is piped to the jq program, to facilitate readability.

    curl -v -X GET -u Administrator:password | jq

    If successful, the call returns an object the initial part of which appears as follows:

        "id": 8243,
        "name": "mutate document",
        "module": "ns_server",
        "description": "Document was mutated via the REST API"
        "id": 8255,
        "name": "read document",
        "module": "ns_server",
        "description": "Document was read via the REST API"
        "id": 8257,
        "name": "alert email sent",
        "module": "ns_server",
        "description": "An alert email was successfully sent"

    Each element in the array thus features the id, name, module, and description of a fiilterable event.

    Return the Current Event-Auditing Configuration

    The current event-auditing configuration can be returned as follows:

    curl -v -X GET -u Administrator:password \ | jq

    If the call is successful, the output resembles the following:

      "disabled": [
      "uid": "40580060",
      "auditdEnabled": true,
      "disabledUsers": [
          "name": "testuser",
          "domain": "local"
          "name": "@eventing",
          "domain": "local"
          "name": "@cbq-engine",
          "domain": "local"
      "logPath": "/opt/couchbase/var/lib/couchbase/logs",
      "rotateInterval": 7200,
      "rotateSize": 524288000

    The output thus provides a list of disabled filterable-event ids. It confirms that event auditing is enabled, and lists disabledUsers: the list shown contains one local user, and two internal (internal users can only be specified on Couchbase Server Version 6.0.3 and later). The current logpath, rotateInterval, and rotateSize are also provided.

    Change the Event-Auditing Configuration

    The following call can be used to modify the event-auditing configuration for the node:

    curl -v -X POST -u Administrator:password \ \
    -d auditdEnabled=true \
    -d disabled=32770,32771,32772,32780,32783,32784,32785,32786 \
    -d disabledUsers=testUser/local,@eventing/local,@cbq-engine/local \
    -d rotateSize=524288000 \
    -d rotateInterval=7200 \
    -d logPath='/opt/couchbase/var/lib/couchbase/logs'

    This call enables event auditing for the current node, by setting auditdEnabled to true. It specifies a list of filterable-event ids as disabled; and specifies one local user and two internal users as disabledUser, ensuring filterable events from these users will not be audited. (Note that internal users can only be specified on Couchbase Server Version 6.0.3 and later.) It also specifies values for rotateSize, rotateInterval, and logPath.
