• The RED method for request-driven services, with exemplars that link a slow bucket to a trace

  Instrument every request-handling service identically with rate, errors and duration: one counter with route, method and status labels and one duration histogram; when tracing exists, attach exemplars (a trace ID with a recorded value) to the histogram so a slow bucket on the dashboard opens the trace that landed there.

• SLIs for queues and batch jobs: age of the oldest message, freshness, coverage and last success

  Request-driven services measure availability and latency; queues and batch jobs need different indicators: how old the oldest unprocessed item is, what proportion of data is fresher than a threshold, what proportion of scheduled runs completed within their window, and when the job last succeeded. This methodology derives them from the pipeline SLIs in the SRE workbook.
