Description

Kiali is unable to fetch Istio traces due to a configuration error.\n

Mitigation

Verify that Kiali is properly configured to use Jaeger:\n\n```yaml\nspec:\n external_services:\n tracing:\n # Enabled by default. Kiali will anyway fallback to disabled if\n # Jaeger is unreachable.\n enabled: true\n # Jaeger service name is \"tracing\" and is in the \"telemetry\" namespace.\n # Make sure the URL you provide corresponds to the non-GRPC enabled endpoint\n # if you set \"use_grpc\" to false.\n internal_url: \"http://tracing.telemetry:16685/jaeger\"\n use_grpc: true\n # Public facing URL of Jaeger\n external_url: \"http://my-jaeger-host/jaeger\"\n```\n
