You can use APISIX's debug mode to troubleshoot your configuration.
## Basic debug mode
You can enable the basic debug mode by adding this line to your debug configuration file (`conf/debug.yaml`):
```yaml title="conf/debug.yaml"
basic:
enable: true
#END
```
APISIX loads the configurations of `debug.yaml` on startup and then checks if the file is modified on an interval of 1 second. If the file is changed, APISIX automatically applies the configuration changes.
:::note
For APISIX releases prior to v2.10, basic debug mode is enabled by setting `apisix.enable_debug = true` in your configuration file (`conf/config.yaml`).
:::
If you have configured two Plugins `limit-conn` and `limit-count` on the Route `/hello`, you will receive a response with the header `Apisix-Plugins: limit-conn, limit-count` when you enable the basic debug mode.
```shell
curl http://127.0.0.1:1984/hello -i
```
```shell
HTTP/1.1 200 OK
Content-Type: text/plain
Transfer-Encoding: chunked
Connection: keep-alive
Apisix-Plugins: limit-conn, limit-count
X-RateLimit-Limit: 2
X-RateLimit-Remaining: 1
Server: openresty
hello world
```
:::info IMPORTANT
If the debug information cannot be included in a response header (for example, when the Plugin is in a stream subsystem), the debug information will be logged as an error log at a `warn` level.
:::
## Advanced debug mode
You can configure advanced options in debug mode by modifying your debug configuration file (`conf/debug.yaml`).
The following configurations are available:
| Key | Required | Default | Description |
|---------------------------------|----------|---------|-----------------------------------------------------------------------------------------------------------------------|
| hook_conf.enable | True | false | Enables/disables hook debug trace. i.e. if enabled, will print the target module function's inputs or returned value. |
| hook_conf.name | True | | Module list name of the hook that enabled the debug trace. |
| hook_conf.log_level | True | warn | Log level for input arguments & returned values. |
| hook_conf.is_print_input_args | True | true | When set to `true` enables printing input arguments. |
| hook_conf.is_print_return_value | True | true | When set to `true` enables printing returned values. |
:::note
A checker would check every second for changes to the configuration file. It will only check a file if the file was updated based on its last modification time.
You can add an `#END` flag to indicate to the checker to only look for changes until that point.
:::
The example below shows how you can configure advanced options in debug mode:
```yaml title="conf/debug.yaml"
hook_conf:
enable: false # Enables/disables hook debug trace
name: hook_phase # Module list name of the hook that enabled the debug trace
log_level: warn # Log level for input arguments & returned values
is_print_input_args: true # When set to `true` enables printing input arguments
is_print_return_value: true # When set to `true` enables printing returned values
hook_phase: # Module function list, Name: hook_phase
apisix: # Referenced module name
- http_access_phase # Function namesArray
- http_header_filter_phase
- http_body_filter_phase
- http_log_phase
#END
```
### Dynamically enable advanced debug mode
You can also enable advanced debug mode only on particular requests.
The example below shows how you can enable it on requests with the header `X-APISIX-Dynamic-Debug`:
```yaml title="conf/debug.yaml"
http_filter:
enable: true # Enable/disable advanced debug mode dynamically
enable_header_name: X-APISIX-Dynamic-Debug # Trace for the request with this header
...
#END
```
This will enable the advanced debug mode only for requests like:
```shell
curl 127.0.0.1:9090/hello --header 'X-APISIX-Dynamic-Debug: foo'
```
:::note
The `apisix.http_access_phase` module cannot be hooked for this dynamic rule as the advanced debug mode is enabled based on the request.
