 ## Debug the agent
 
+> The `grpc_level` was [introduced](https://gitlab.com/gitlab-org/cluster-integration/gitlab-agent/-/merge_requests/669) in GitLab 15.1.
+
 To debug the cluster-side component (`agentk`) of the agent, set the log
 level according to the available options:
 
-- `off`
-- `warning`
 - `error`
+- `warning`
 - `info`
 - `debug`
 
-The log level defaults to `info`. You can change it by using a top-level `observability`
-section in the [agent configuration file](install/index.md#configure-your-agent), for example setting the level to `debug`:
+The agent has two loggers:
+
+- A general purpose logger, which defaults to `info`.
+- A gRPC logger, which defaults to `error`.
+
+One can change their log levels by using a top-level `observability` section in the [agent configuration file](install/index.md#configure-your-agent), for example setting the levels to `debug` and `warning`:
 
 ```yaml
 observability:
   logging:
     level: debug
+    grpc_level: warning
 ```
 
+When `grpc_level` is set to `info` or below, there will be a lot of gRPC logs.
