External API issue alerting in our service

[Imran_Siddiqui]

Hi Team,

I have a application say COD im which I have some external API call

Is there anyway I can alert/notify in dynatrace in these cases:

• If external api is throwing 500
• If external api is throwing 401
• External api is not reachable

To set up alerts or notifications in Dynatrace for specific issues with your external API calls, such as receiving a 500 error, a 401 error, or when the external API is not reachable, you can use the following steps:

• Create Custom Service for External API:

  • First, ensure that your external API calls are being tracked as a service in Dynatrace. You might need to define a custom service for the API endpoints if they are not automatically detected.
    • click on the right site "Monitor as a separate service"

• Create Custom Metrics:

  • create custom metrics to count the occurrences of specific status codes.
    • click on the right site "Creare metric"

• Define Anomaly Detection Custom Metric Alert:

  • Create anomaly detection on the custom metrics. You can specify the conditions under which the alerts should be triggered, such as a specific number of 500 errors, 401 errors, or when the API is not reachable for a certain period. You can use data explorer to get the count metric and filter by error code filtering by status code starts with 5, 4 or missing. Example

:filter(and(or(prefix("HTTP status","5"))))
:filter(and(or(prefix("HTTP status","4"))))
:filter(and(or(eq("HTTP status","missing"))))
