# How to Check for Fluent Bit Internal Errors

To check for internal errors in Fluent Bit, you should set the `Log_Level` option in the `[SERVICE]` section to `debug`:

```text
[label fluent-bit.conf]
# Service Section
[SERVICE]
    Flush        1
    Daemon       off
[highlight]
    Log_Level    debug
[/highlight]
...
```
When you restart Fluent Bit, you will see logs with internal errors and debug information:

```text
[output]
...
[2024/08/05 10:55:05] [debug] [out flush] cb_destroy coro_id=230
[2024/08/05 10:55:05] [debug] [task] destroy task=0x7f5439e76020 (task_id=0)
