Faster exception triage and one-step alerts from logs

Improvements Fixes

TL;DR

Separate a new exception from a long-noisy one, line spikes up against deploys, and turn a live log query into an alert without saving it first.

Faster exception triage and one-step alerts from logs

Improvements

  • Discover Exceptions
    • Triage filters for Spiking, New, Ignored, and Unflagged let you separate a genuinely new error from one that has been noisy for a month. You can ignore or suppress a known exception group, and toggle an adaptive alert on any group in one click
    • The overview chart plots occurrences over time with deployment markers overlaid, so a spike that starts at a deploy is obvious
  • Logs: Create an alert directly from the Logs Explorer action menu using the query. Saving the query first is no longer a prerequisite, though it is still needed to re-open and manage the alert later

Fixes

  • AI Assistant
    • Tables and markdown in Slack replies rendered as plain text intermittently
    • The Troubleshoot icon was broken on the AI Assistant page
  • Discover Kubernetes: Cluster filters were not stored in the URL and were lost on auto-refresh, and auto-refresh reloaded the whole page instead of only the numbers and the table
  • Discover Applications (RUM)
    • The React Native RUM SDK failed a first or clean Android build during configureCMakeDebug because autolinking referenced a codegen directory that did not exist
    • initialize() and getSessionId() could return an empty session ID on iOS when the session started asynchronously
    • The Android RUM SDK pulled in an unused OpenTelemetry android-agent dependency that forced consumers onto Android Gradle Plugin 8.9.1 or newer
  • Logs: The logs chart left an empty gap of one timeslice at the end of the x-axis
  • Metrics: Pasting text into Metrics Explorer PromQL editor did not work
  • Alerting
    • Scheduled-search emails showed the raw query instead of matching log context, and did not consistently use the configured summary and description. Resolved notifications could also lose their resolved identity when a custom summary was set
    • The Alert Monitor refresh-interval dropdown listed the acknowledgement filter options instead of 1m / 3m / 5m / 10m
    • Fetching alert rules as YAML timed out and returned a 500 for tenants with large rule counts
  • Control Plane: The calendar in Data Usage hid the first date row when downloading a CSV
