05/13/2025, 8:50 AMHi, using Auto-instrumentation without Sidecar
https://signoz.io/docs/tutorial/opentelemetry-operator-usage/#auto-instrumentation-without-sidecar
and deployed spring-petclinic, but I did not get any logs or monitoring in signoz UI self host.
Deployed Signoz services using helm signoz/signoz, cert-manager, and opentelemetry-operator-system. Do I miss anything?
Is it enough if I use my own Java application, Auto-instrumentation, and passing inject-java in deployment, or do I still need to set up opentelemetry-javagent in my code?

self-host.

05/15/2025, 9:21 AM@Nagesh Bansal if I am passing opentelemetry-javagent in my code still OpenTelemetryCollector and instrumentation should be deployed k8s env?

05/15/2025, 9:35 AMHey Rakshith, when you're using the opentelemetry-operator and passing the
inject-javaNagesh Bansal

• OpenTelemetry Collector
• auto-instrumentation of the workloads using OpenTelemetry instrumentation libraries

In this Instrumentation
which one I should deploy
1. https://signoz.io/blog/using-signoz-to-monitor-your-kubernetes-cluster/#auto-instrumenting-your-application
2. https://github.com/open-telemetry/opentelemetry-operator/tree/main?tab=readme-ov-file#opentelemetry-auto-instrumentation-injection

05/15/2025, 12:48 PMafter deploying signoz/k8s-infra able to get all services logs in ui.
and deployed opentelemetry-operator for getting pod monitoring, metrics, graphs and added instrumentation.opentelemetry.io/inject-java: "true"
but I don't see anything UI.
