  • Method Details

    • queryLanguage

      public final QueryLanguage queryLanguage()

      Specify the query language to use for this query. The options are Logs Insights QL, OpenSearch PPL, and OpenSearch SQL. For more information about the query languages that CloudWatch Logs supports, see Supported query languages.

      If the service returns an enum value that is not available in the current SDK version, queryLanguage will return QueryLanguage.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from queryLanguageAsString().

      Returns:
      Specify the query language to use for this query. The options are Logs Insights QL, OpenSearch PPL, and OpenSearch SQL. For more information about the query languages that CloudWatch Logs supports, see Supported query languages.

    • logGroupName

      public final String logGroupName()

      The log group on which to perform the query.

      A StartQuery operation must include exactly one of the following parameters: logGroupName, logGroupNames, or logGroupIdentifiers. The exception is queries using the OpenSearch Service SQL query language, where you specify the log group names inside the querystring instead of here.

      Returns:
      The log group on which to perform the query.

      A StartQuery operation must include exactly one of the following parameters: logGroupName, logGroupNames, or logGroupIdentifiers. The exception is queries using the OpenSearch Service SQL query language, where you specify the log group names inside the querystring instead of here.

    • hasLogGroupNames

      public final boolean hasLogGroupNames()
      For responses, this returns true if the service returned a value for the LogGroupNames property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • logGroupNames

      public final List<String> logGroupNames()

      The list of log groups to be queried. You can include up to 50 log groups.

      A StartQuery operation must include exactly one of the following parameters: logGroupName, logGroupNames, or logGroupIdentifiers. The exception is queries using the OpenSearch Service SQL query language, where you specify the log group names inside the querystring instead of here.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasLogGroupNames() method.

      Returns:
      The list of log groups to be queried. You can include up to 50 log groups.

    • hasLogGroupIdentifiers

      public final boolean hasLogGroupIdentifiers()
      For responses, this returns true if the service returned a value for the LogGroupIdentifiers property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • logGroupIdentifiers

      public final List<String> logGroupIdentifiers()

      The list of log groups to query. You can include up to 50 log groups.

      You can specify them by the log group name or ARN. If a log group that you're querying is in a source account and you're using a monitoring account, you must specify the ARN of the log group here. The query definition must also be defined in the monitoring account.

      If you specify an ARN, use the format arn:aws:logs:region:account-id:log-group:log_group_name Don't include an * at the end.

      A StartQuery operation must include exactly one of the following parameters: logGroupName, logGroupNames, or logGroupIdentifiers. The exception is queries using the OpenSearch Service SQL query language, where you specify the log group names inside the querystring instead of here.

    • startTime

      public final Long startTime()

      The beginning of the time range to query. The range is inclusive, so the specified start time is included in the query. Specified as epoch time, the number of seconds since January 1, 1970, 00:00:00 UTC.

      Returns:
      The beginning of the time range to query. The range is inclusive, so the specified start time is included in the query. Specified as epoch time, the number of seconds since January 1, 1970, 00:00:00 UTC.

    • endTime

      public final Long endTime()

      Returns:
      The end of the time range to query. The range is inclusive, so the specified end time is included in the query. Specified as epoch time, the number of seconds since January 1, 1970, 00:00:00 UTC.

    • limit

      public final Integer limit()

      The maximum number of log events to return in the query. If the query string uses the fields command, only the specified fields and their values are returned. The default is 10,000.

      Specified by:
      toBuilder in interface ToCopyableBuilder<StartQueryRequest.Builder,StartQueryRequest>
      Specified by:
      toBuilder in class CloudWatchLogsRequest
      Returns:
      a builder for type T

    • builder

      public static StartQueryRequest.Builder builder()

    • serializableBuilderClass

      public static Class<? extends StartQueryRequest.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class AwsRequest

    • equals

      public final boolean equals(Object obj)
      Overrides:

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)
      Description copied from class: SdkRequest
      Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkRequest

      Optional containing the casted return value
