Response Structure

(dict) –

Health details for an AWS Elastic Beanstalk environment.
- EnvironmentName (string) –
  
  The environment’s name.
- HealthStatus (string) –
  
  The health status of the environment. For example, Ok.
- Status (string) –
  
  The environment’s operational status. Ready, Launching, Updating, Terminating, or Terminated.
- Color (string) –
  
  The health color of the environment.
- Causes (list) –
  
  Descriptions of the data that contributed to the environment’s current health status.
  - (string) –
- ApplicationMetrics (dict) –
  
  Application request metrics for the environment.
  - Duration (integer) –
    
    The amount of time that the metrics cover (usually 10 seconds). For example, you might have 5 requests ( request_count) within the most recent time slice of 10 seconds ( duration).
  - RequestCount (integer) –
    
    Average number of requests handled by the web server per second over the last 10 seconds.
  - StatusCodes (dict) –
    
    Represents the percentage of requests over the last 10 seconds that resulted in each type of status code response.
    - Status2xx (integer) –
      
      The percentage of requests over the last 10 seconds that resulted in a 2xx (200, 201, etc.) status code.
    - Status3xx (integer) –
      
      The percentage of requests over the last 10 seconds that resulted in a 3xx (300, 301, etc.) status code.
    - Status4xx (integer) –
      
      The percentage of requests over the last 10 seconds that resulted in a 4xx (400, 401, etc.) status code.
    - Status5xx (integer) –
      
      The percentage of requests over the last 10 seconds that resulted in a 5xx (500, 501, etc.) status code.
  - Latency (dict) –
    
    Represents the average latency for the slowest X percent of requests over the last 10 seconds. Latencies are in seconds with one millisecond resolution.

  - Pending (integer) –
    
    Grey. An operation is in progress on an instance within the command timeout.
  - Ok (integer) –
    
    Green. An instance is passing health checks and the health agent is not reporting any problems.

Examples

The following operation retrieves overall health information for an environment named my-env:

response = client.describe_environment_health(
    AttributeNames=[
        'All',
    ],
    EnvironmentName='my-env',
)

print(response)
