.. py:method:: ForecastService.Client.create_monitor(**kwargs)

  

  Creates a predictor monitor resource for an existing auto predictor. Predictor monitoring allows you to see how your predictor's performance changes over time. For more information, see `Predictor Monitoring <https://docs.aws.amazon.com/forecast/latest/dg/predictor-monitoring.html>`__.

  ::

    response = client.create_monitor(
        MonitorName='string',
        ResourceArn='string',
        Tags=[
            {
                'Key': 'string',
                'Value': 'string'
            },
        ]
    )
    
  :type MonitorName: string
  :param MonitorName: **[REQUIRED]** 

    The name of the monitor resource.

    

  
  :type ResourceArn: string
  :param ResourceArn: **[REQUIRED]** 

    The Amazon Resource Name (ARN) of the predictor to monitor.

    

  
  :type Tags: list
  :param Tags: 

    A list of `tags <https://docs.aws.amazon.com/forecast/latest/dg/tagging-forecast-resources.html>`__ to apply to the monitor resource.

    

  
    - *(dict) --* 

      The optional metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.

       

      The following basic restrictions apply to tags:

       

      
      * Maximum number of tags per resource - 50.
       
      * For each resource, each tag key must be unique, and each tag key can have only one value.
       
      * Maximum key length - 128 Unicode characters in UTF-8.
       
      * Maximum value length - 256 Unicode characters in UTF-8.
       
      * If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
       
      * Tag keys and values are case sensitive.
       
      * Do not use ``aws:``, ``AWS:``, or any upper or lowercase combination of such as a prefix for keys as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys with this prefix. Values can have this prefix. If a tag value has ``aws`` as its prefix but the key does not, then Forecast considers it to be a user tag and will count against the limit of 50 tags. Tags with only the key prefix of ``aws`` do not count against your tags per resource limit.
      

      

    
      - **Key** *(string) --* **[REQUIRED]** 

        One part of a key-value pair that makes up a tag. A ``key`` is a general label that acts like a category for more specific tag values.

        

      
      - **Value** *(string) --* **[REQUIRED]** 

        The optional part of a key-value pair that makes up a tag. A ``value`` acts as a descriptor within a tag category (key).
