Evaluation fails

Lighthouse failed because

Evaluation fails and the shipyard-controller reports:

lighthouse failed because...

No evaluation performed by Lighthouse

In this case the Lighthouse performed no evaluation because the received sh.keptn.event.get-sli.finished event had a result of fail. The root cause can be identified from the message field of this event.

In instances where this is related to a specific SLI, check the message field of the individual SLI result in the within indicatorValues. This can be viewed in Keptn UI by expanding the sh.keptn.event.get-sli.finished event and viewing its payload:

The following subsections detail some common messages as well as likely causes and solutions:

Message: could not query Dynatrace dashboard for SLIs: error while processing dashboard config '12345678-1234-1234-1234-12345678abcd': Dynatrace API error (404): Dashboard 12345678-1234-1234-1234-12345678abcd not found

Likely cause

Suggested solution

  • If SLIs and SLOs should be sourced from a dashboard, ensure dynatrace/dynatrace.conf.yaml contains a dashboard: <dashboard-id> entry with the correct dashboard ID, or
  • If SLIs and SLOs should be defined using YAML files, remove the dashboard: <dashboard-id> entry from dynatrace/dynatrace.conf.yaml

Message: could not query Dynatrace dashboard for SLIs: error while processing dashboard config '': no dashboard name matches the name specification...

Likely cause

  • Dynatrace-service is configured to query a dashboard for SLIs (i.e. dynatrace/dynatrace.conf.yaml contains dashboard: query) but no dashboard named with the pattern KQG;project=<project>;service=<service>;stage=<stage> is available

Suggested solution

  • If SLIs and SLOs should be sourced from a dashboard, create a dashboard named with the pattern KQG;project=<project>;service=<service>;stage=<stage> in the Dynatrace tenant, or
  • If SLIs and SLOs should be defined using YAML files, remove the dashboard: query entry from dynatrace/dynatrace.conf.yaml
