Details
The Kong - Prometheus extension uses the Kong Prometheus Export to scrape and ingest metrics.
It enables the Prometheus extension in your Kong environment.
It points the Dynatrace monitoring configuration to the metrics endpoint, for example, http://localhost:<port>/metrics.
In this context, Dynatrace is the Prometheus server.
Dynatrace creates the following custom topology types from the Prometheus metric dimensions:
kong.node- Kong
shared dictionary - Kong service
A SAME_AS relationship is defined between the Kong service and a monitored Dynatrace service, where the service names are the same.
Feature sets
When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly the extension has to collect at least one metric after the activation.
In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.
All metrics that aren't categorized into any feature set are considered to be the default and are always reported.
A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.
