Return Slow Queries

GET /api/atlas/v2/groups/{groupId}/processes/{processId}/performanceAdvisor/slowQueryLogs

Returns log lines for slow queries that the Performance Advisor and Query Profiler identified. The Performance Advisor monitors queries that MongoDB considers slow and suggests new indexes to improve query performance. MongoDB Cloud bases the threshold for slow queries on the average time of operations on your cluster. This enables workload-relevant recommendations. To use this resource, the requesting Service Account or API Key must have any Project Data Access role or the Project Observability Viewer role.

Path parameters

  • groupId string Required

    Unique 24-hexadecimal digit string that identifies your project. Use the /groups endpoint to retrieve all projects to which the authenticated user has access.

    NOTE: Groups and projects are synonymous terms. Your group id is the same as your project id. For existing groups, your group/project id remains the same. The resource and corresponding endpoints use the term groups.

    Format should match the following pattern: ^([a-f0-9]{24})$.

  • processId string Required

    Combination of host and port that serves the MongoDB process. The host must be the hostname, FQDN, IPv4 address, or IPv6 address of the host that runs the MongoDB process (mongod or mongos). The port must be the IANA port on which the MongoDB process listens for requests.

    Format should match the following pattern: ^([0-9]{1,3}\.){3}[0-9]{1,3}|([0-9a-f]{1,4}\:){7}([0-9a-f]{1,4})|(([a-z0-9]+\.){1,10}[a-z]+)?(\:[0-9]{4,5})$.

Query parameters

  • envelope boolean

    Flag that indicates whether Application wraps the response in an envelope JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.

    Default value is false.

  • pretty boolean

    Flag that indicates whether the response body should be in the prettyprint format.

    Default value is false.

    Prettyprint
  • duration integer(int64)

    Length of time expressed during which the query finds slow queries among the managed namespaces in the cluster. This parameter expresses its value in milliseconds.

    • If you don't specify the since parameter, the endpoint returns data covering the duration before the current time.
    • If you specify neither the duration nor since parameters, the endpoint returns data from the previous 24 hours.
  • namespaces array[string]

    Namespaces from which to retrieve slow queries. A namespace consists of one database and one collection resource written as .: <database>.<collection>. To include multiple namespaces, pass the parameter multiple times delimited with an ampersand (&) between each namespace. Omit this parameter to return results for all namespaces.

  • nLogs integer(int64)

    Maximum number of lines from the log to return.

    Minimum value is 0, maximum value is 20000. Default value is 20000.

  • since integer(int64)

    Date and time from which the query retrieves the slow queries. This parameter expresses its value in the number of milliseconds that have elapsed since the UNIX epoch.

    • If you don't specify the duration parameter, the endpoint returns data covering from the since value and the current time.
    • If you specify neither the duration nor the since parameters, the endpoint returns data from the previous 24 hours.

    Minimum value is 1199145600000.

  • includeMetrics boolean

    Whether or not to include metrics extracted from the slow query log as separate fields.

    Default value is false.

  • includeReplicaState boolean

    Whether or not to include the replica state of the host when the slow query log was generated as a separate field.

    Default value is false.

  • includeOpType boolean

    Whether or not to include the operation type (read/write/command) extracted from the slow query log as a separate field.

    Default value is false.

        • docsExamined integer(int64)

          The number of documents in the collection that MongoDB scanned in order to carry out the operation.

        • docsExaminedReturnedRatio number(double)

          Ratio of documents examined to documents returned.

        • docsReturned integer(int64)

          The number of documents returned by the operation.

        • fromUserConnection boolean

          This boolean will be true when the server can identfiy the query source as non-server. This field is only available for MDB 8.0+.

        • hasIndexCoverage boolean

          Indicates if the query has index coverage.

        • hasSort boolean

          This boolean will be true when a query cannot use the ordering in the index to return the requested sorted results; i.e. MongoDB must sort the documents after it receives the documents from a cursor.

        • keysExamined integer(int64)

          The number of index keys that MongoDB scanned in order to carry out the operation.

        • keysExaminedReturnedRatio number(double)

      • namespace string

        Human-readable label that identifies the namespace on the specified host. The resource expresses this parameter value as <database>.<collection>.

      • opType string
