The meaning of each item in server information is following: | Name | Type | Description | |---------|------|-------------| | up_time | integer | Elapsed time (in seconds) since APISIX instance was launched, value will be reset when you hot updating APISIX but is kept for intact if you just reloading APISIX. | | boot_time | integer | Bootstrap time (UNIX timestamp) of the APISIX instance, value will be reset when you hot updating APISIX but is kept for intact if you just reloading APISIX. | | last_report_time | integer | Last reporting time (UNIX timestamp). | | id | string | APISIX instance id. | | etcd_version | string | The etcd cluster version that APISIX is using, value will be `"unknown"` if the network (to etcd) is partitioned. | | version | string | APISIX version. | | hostname | string | Hostname of the machine/pod that APISIX is deployed. | ## 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 ...... ```
