Log events

An event is a meaningful occurrence produced when an enabled rule matches parsed log data. Events replace manual line-by-line reading with searchable operational facts.

Depending on the rule, an event can represent:

  • One occurrence, such as an error or retry.
  • The start or end of a measured duration.
  • A derived numeric measurement.

Events are evidence, not interruptions​

An event does not automatically create an alert. Monitoring-only rules create events for history, charts, and investigation without notifying anyone. An alert appears only when an attached alerting condition is met, or when an SPC control fires.

Explore events​

Open Investigate → Log Events to filter and inspect events. An event's details can link back to its:

  • Instrument and instrument type.
  • Rule and category.
  • Source file and line evidence.
  • Method and run.
  • Related alerts.

Start from an alert or run when you already know the affected operation. Start from Log Events when you want to search for a repeated pattern across files, instruments, or time.

See Rules for how events are defined and Alerts for how important events enter the response workflow.
