Keptn placeholders

SLI queries (see SLIs via dynatrace/sli.yaml files) as well as certain values in dynatrace/dynatrace.conf.yaml files may include placeholders which are automatically replaced with values from the Keptn event or environment variables. This is very powerful as you can define generic sli.yaml files and leverage the dynamic data of a Keptn event.

Standard placeholders for Keptn event values

The following table provides an outline of supported placeholders:

Placeholder	Description
$CONTEXT	Unique UUID value that connects various events together
$EVENT	The type of the Keptn event
$SOURCE	The source of the Keptn event
$PROJECT	The Keptn project
$STAGE	The Keptn stage
$SERVICE	The Keptn service
$DEPLOYMENT	The Keptn deployment
$TESTSTRATEGY	The test strategy

Keptn event label placeholders

Keptn events may also include labels, a collection of key-value pairs passed with a Keptn event. These may be then referenced as placeholders using the syntax $LABEL.<key>. For example, if an evaluation is triggered from the CLI using:

keptn trigger evaluation --project test-project --stage quality-gate --service=test-service --labels="my-label=my-value"

The label my-label may be referenced using the placeholder $LABEL.my-label.

Environment variable placeholders

All environment variable key-value pairs available to the dynatrace-service may be referenced using the placeholder $ENV.<key>.
