get_health_event#

CloudWatchInternetMonitor.Client.get_health_event(**kwargs)#

Gets information that Amazon CloudWatch Internet Monitor has created and stored about a health event for a specified monitor. This information includes the impacted locations, and all the information related to the event, by location.

The information returned includes the impact on performance, availability, and round-trip time, information about the network providers (ASNs), the event type, and so on.

Request Syntax

response = client.get_health_event(
    MonitorName='string',
    EventId='string',
    LinkedAccountId='string'
)
Parameters:

  • MonitorName (string) –

    [REQUIRED]

    The name of the monitor.

  • EventId (string) –

    [REQUIRED]

    The internally-generated identifier of a health event. Because EventID contains the forward slash (“/”) character, you must URL-encode the EventID field in the request URL.

  • LinkedAccountId (string) – The account ID for an account that you’ve set up cross-account sharing for in Amazon CloudWatch Internet Monitor.
