  • Alerts: critical events that require attention.
  • Common events: non-critical events, such as instance start and some errors.
  • Event logs: important events that are detected by the log exception analysis feature of EMR-APM. The event logs facilitate troubleshooting and help you locate issues. Event logs contain the details about service exceptions and are more comprehensive than alerts generated from metric analysis.
