## How to Enable
Just configure `server-info` in the plugin list of the configuration file `conf/config.yaml`.
```
plugins: # plugin list
- example-plugin
- limit-req
- node-status
- server-info
- jwt-auth
- zipkin
......
```
## How to customize the server info report configurations
We can change the report configurations in the `plugin_attr` section of `conf/config.yaml`.
| Name | Type | Default | Description |
| ------------ | ------ | -------- | -------------------------------------------------------------------- |
| report_interval | integer | 60 | the interval to report server info to etcd (unit: second, maximum: 3600, minimum: 60). |
| report_ttl | integer | 7200 | the live time for server info in etcd (unit: second, maximum: 86400, minimum: 3600). |
Here is an example, which modifies the `report_interval` to 10 minutes and sets the `report_ttl` to one hour.
```yaml
plugin_attr:
server-info:
report_interval: 600,
report_ttl: 3600
```
## Test Plugin
