Log View Widget

This is a Graylog Enterprise feature. A valid Graylog Enterprise license is required.

Log View is a widget that presents log data in a format similar to common log format and resembles a console display. The Log View widget allows you to scroll through log events as new lines populate in real-time.

The Log View widget provides a way to investigate your log events, so you can:

  • Record faults to diagnose and debug.
  • Identify security breaches and other system and network misuses.
  • Perform audits.

The Log View widget allows you to create highly customizable reports and info graphics, add reports to your dashboards, and save and retrieve reports in the event you need to review that data. You can add new values, fields, and metrics to build reports that meet your needs.

Hint: Graylog Open is limited to exports in CSV, as detailed in Export Search Results. However, there are additional formats available in Enterprise: PDF, GELF (newline-delimited), JSON, NDJSON (Newline-Delimited JSON), and Plain Text form.

  • Data to a logging library built in JavaScript (e.g. JSON ).
  • Structured data objects to TCP or UNIX pipes (e.g. NDJSON ).

If configured, you can use the dashboard created above in the Create a Log View Widget section.
