 It is important to note that the LLM calls and the other events are tracked together in different modules of AgentOps. By default, all the LLM calls are tracked when the AgentOps client is initialized. However, the other events are only tracked when the `TaskWeaverEventHandler` handler is used in conjunction within the code.
 
 Therefore, event observability is limited to LLM calls when TaskWeaver is used in [Terminal mode](../usage/cmd.md).
