## Attributes

None

|
## API
|
|
|
|
This plugin exposes one API `/v1/server_info` to [Control API](../control-api.md).
|
|
|
|
## 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
|
|
|
|
After enabling this plugin, you can access these data through the plugin Control API:
|
|
|
|
```shell
|
|
$ curl http://127.0.0.1:9090/v1/server_info -s | jq .
|
|
{
|
|
"etcd_version": "3.5.0",
|
|
"up_time": 9460,
|
|
"last_report_time": 1608531519,
|
|
"id": "b7ce1c5c-b1aa-4df7-888a-cbe403f3e948",
|
|
"hostname": "fedora32",
|
|
"version": "2.1",
|
|
"boot_time": 1608522102
|
|
}
|
|
```
|
|
|
|
The APISIX Dashboard will collects server info in etcd, so you may also try to check them through Dashboard.
|
|
|
|
## Disable Plugin
|
|
|
|
Remove `server-info` in the plugin list of configure file `conf/config.yaml`.
|
|
|
|
```
|
|
plugins: # plugin list
|
|
- example-plugin
|
|
- limit-req
|
|
- node-status
|
|
- jwt-auth
|
|
- zipkin
|
|
......
|
|
```
