How visualizing logs converted to traces can uncover performance problems

Interruptions in a service and no clue why it happened? Visualizations help to identify problems and give more insight into how a service actually behaved. In some situations, logging is supported, but traces that can help find root cause are missing. What if you could turn logs into traces? In this talk, OpenValue Software Engineer and SRE Cees Bos will show how to transform log files from two interacting services into custom traces and load them into Grafana, identify problems that are not visible without created traces, and then verify that the subsequent fixes worked. Problem hunting isn’t always easy, but tools like Promtail, Loki, logcli, and the trace visualization in Grafana can be used to find issues in an uncommon way if the common way is not good enough.
