Breaking changes in 6.4.0

We previously split APM data into separate indices (transaction, span, error, etc.). In 6.4 APM Kibana UI starts to leverage those separate indices for queries.

In case you only update Kibana but run an older version of APM Server you will not be able to see any APM data by default. To fix this, use the Kibana APM settings to specify the location of the APM index:

apm_oss.errorIndices: apm-*
apm_oss.spanIndices: apm-*
apm_oss.transactionIndices: apm-*
apm_oss.onboardingIndices: apm-*

In case you are upgrading APM Server from an older version, you might need to refresh your APM index pattern for certain APM UI features to work. Also ensure to add the new config options in apm-server.yml in case you keep your existing configuration file:

output.elasticsearch:
  indices:
    - index: "apm-%{[observer.version]}-sourcemap"
      when.contains:
        processor.event: "sourcemap"
    - index: "apm-%{[observer.version]}-error-%{+yyyy.MM.dd}"
      when.contains:
        processor.event: "error"
    - index: "apm-%{[observer.version]}-transaction-%{+yyyy.MM.dd}"
      when.contains:
        processor.event: "transaction"
    - index: "apm-%{[observer.version]}-span-%{+yyyy.MM.dd}"
      when.contains:
        processor.event: "span"
    - index: "apm-%{[observer.version]}-metric-%{+yyyy.MM.dd}"
      when.contains:
        processor.event: "metric"
    - index: "apm-%{[observer.version]}-onboarding-%{+yyyy.MM.dd}"
      when.contains:
        processor.event: "onboarding"
