Course Description

This course is designed for developers responsible for debugging their own applications, and for SREs responsible for troubleshooting performance issues. The Splunk Log Observer is built primarily for DevOps teams working on applications built on modern tech stacks (containerized micro-services). It describes how to use the tool to work with log data using the no-code user interface. Learn to create, save, and share search filters, and to investigate the shape of your log data. Analyze logs with aggregation functions and group by rules. Create rules to manipulate incoming data, as well as generate synthetic metrics from log data.
