What is the difference between Error Tracking and standard log-based error monitoring?
Standard log-based error monitoring treats every error occurrence as its own separate log line - to understand whether an error is new, worsening, or recurring, someone has to manually search and eyeball the pattern across many individual entries.
Error Tracking automatically groups and deduplicates those occurrences into a single issue based on stack trace and error signature, tracking occurrence count, first-seen/last-seen timestamps, and affected service as one continuously updating record instead of scattered lines.
This turns 'search logs for this error message' into 'look at this issue's trend,' which is materially faster during triage, especially for errors with slightly varying messages (like different IDs embedded in the text) that a plain log search might otherwise treat as unrelated.
