Python

1) CRD installation

You can create one by searching for Infrastructure - Custom Resources - 'instrumentations'.

You can create it by clicking the Create button, selecting the namespace where you want to collect logs, and modifying the form below.

The above CRD is applied on a namespace basis, and automatic container logs can be collected for other languages in the same namespace.

log-agent Service Address : Infrastructure - Cluster - Add-ons - Click 'log-agent' and check the service name.

( http port = 4318 , grpc port = 4317)

2) Add annotations to the applications you want to collect

Add annotations to the workloads in the namespace for which you want to collect logs.

Application - Service Map - Service Map to collect logs - Workload - Select the application to collect logs - Click the "Settings" button.

Change the Yaml view and add the following annotations to the template - metadata - annotations section.

3) Add service name and token value to environment variables.

4. Check Application log

1) Logging - Application Log - Search for the application you set in the application list.
