We do run Chaos engineering tests on the applications. The applications are currently publishing the metrics to Dynatrace. We want to generate custom events each time when Chaos experiments are run on the target application / host. So that we know Chaos experiments were run on the specific target and hence we know the reason for variation in the specific application metrics (which were impacted through chaos tests).
The Document: https://www.dynatrace.com/support/help/dynatrace-api/environment-api/events/post-event/#expand-the-e... Describes type of events supported by Dynatrace.
We want to differentiate the chaos experiment events at Dynatrace using specific event type name (example chaos-experiment).
You cannot retract or update the event for the event types you mentioned above. For problem events it can be closed or extended. But info events cannot be updated later.
The documentation also states that "The time of event closure is already known and the event IDs are returned instantly."
