What types of log searching capabilities does it offer?

Accepted Answer

The tool offers robust log searching capabilities including 'absolute timestamp search' for specific time ranges, 'relative timestamp search' for recent logs (e.g., last 15 minutes or 24 hours), and filtering by Graylog stream IDs. All queries support Elasticsearch syntax for powerful and flexible log analysis.

Question 3

Can I discover available Graylog streams and check system health with this tool?

Accepted Answer
