# Logs

The logs tab provides access to both individual log messages and agent execution sessions which contain all of the log messages from that specific session.

Each of these serves a specific purpose with respect to diagnosing issues with flows.

For example, the message log provides the ability to filter message by severity level so that you can easily find "Errors" or "Fatal" errors across multiple sessions.

The session log is more useful when you are trying to diagnose an issue with the execution of a flow in response to a specific request/message.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.contextual.io/documentation-and-resources/components-and-data/agents/agent-details/logs.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
