 This section introduces how to modify the configuration of TiCDC cluster using the  [`tiup cluster edit-config`](/tiup/tiup-component-cluster-edit-config.md) command of TiUP. The following example changes the value of `gc-ttl` from the default `86400` to `3600`, namely, one hour.

-## Use HTTP interface to manage cluster status and data replication task
-
-Currently, the HTTP interface provides some basic features for query and maintenance.
-
-In the following examples, suppose that the TiCDC server listens on `127.0.0.1`, and the port is `8300` (you can specify the IP and port in `--addr=ip:port` when starting the TiCDC server).
-
-### Get the TiCDC server status
-
-Use the following command to get the TiCDC server status:
-
-{{< copyable "shell-regular" >}}
-
-```shell
-curl http://127.0.0.1:8300/status
-```
-
-```

-### Evict the owner node
-
-{{< copyable "shell-regular" >}}
-
-```shell
-curl -X POST http://127.0.0.1:8300/capture/owner/resign

-
-For nodes other than owner nodes, executing the above command will return the following error.

-```shell
-curl -X POST -d '"debug"' http://127.0.0.1:8301/admin/log

-In the command above, the `POST` parameter indicates the new log level. The [zap-provided](https://godoc.org/go.uber.org/zap#UnmarshalText) log level options are supported: "debug", "info", "warn", "error", "dpanic", "panic", and "fatal". This interface parameter is JSON-encoded and you need to pay attention to the use of quotation marks. For example: `'"debug"'`.
