Logs & live tail ​

Monitor → Logs shows every log line from your agents and your OpenTelemetry apps.

Search and filter ​

  • Time range: 15 minutes, 1 hour, 4 hours, 24 hours or 7 days.
  • Search: type text to find messages that contain it. The search ignores case and matches anywhere in the message.
  • Side facets: Status, Service and Host, each with a count per value. Select several values in a facet to match any of them; selections in different facets must all match.
  • Status buttons above the list give quick filters for critical, error, warning, info and debug.
  • Histogram: event volume over the selected range, colored by status. It's a fast way to spot spikes.

Click a row to expand it and see the full message, its file path and its tags. For logs from OpenTelemetry, a View trace → link opens the related trace.

Load older logs at the bottom of the list fetches the next page.

Retention ​

Logs are kept for 7 days by default, then deleted automatically. Your Logcore administrator can change this.

Tips ​

  • If a service is too noisy, drop its noise at the source with exclude. This keeps the dashboard fast and saves bandwidth.
  • Give services clear names (checkout-api, not app). The name is what you filter by.
  • Use monitors so you don't have to watch the screen.
