Graceful unpublishing

The following example shows the event that EventBridge receives when an application is gracefully released:

{
    "specversion":"1.0",
    "subject":"",
    "source":"acs.mse",
    "data":{
        "framework":"SPRING CLOUD",
        "extraInfo":"SUCCESS, no spring cloud registry found",
        "timestamp":1596455074797
    },
    "datacontenttype":"application/json",
    "type":"mse:Agent:GracefulShutdown",
    "id":"0d6a3880-cc34-45ac-a53e-d26ae218****",
    "time":"2020-11-19T21:04:41+08:00",

    "aliyunpublishtime":"2020-11-19T21:04:42.179PRC",
    "aliyuneventbusname":"default",
    "aliyunregionid":"cn-hangzhou",
    "aliyunpublishaddr":"172.25.XX.XX"
}

The following table describes the parameters contained in data.


Parameter	Type	Example	Description

timestamp	Timestamp	1596455074797	The timestamp that indicates when the application was gracefully released.

Removal of outlier instances

The following example shows the event that EventBridge receives when an outlier instance is removed from an application:

{
    "specversion":"1.0",
    "subject":"",
    "source":"acs.mse",
    "data":{
        "framework":"DUBBO",
        "extraInfo":"172.22.XX.XX:20880 IsolationContext{isolationTimeMultiple=780, recoverTime=1608518836265}",
        "timestamp":1608518536265
    },
    "datacontenttype":"application/json",
    "type":"mse:Agent:OutlierEjection",
    "id":"170d56b6-9efe-420b-affb-16ab9adb****",

    "aliyunpublishaddr":"172.22.XX.XX"
}

The following table describes the parameters contained in data.


Parameter	Type	Example	Description
framework	String	DUBBO	The framework of the call. Valid values: SPRING CLOUD DUBBO
extraInfo	String	172.22.XX.XX:20880 IsolationContext{isolationTimeMultiple=780, recoverTime=1608518836265	The message.
timestamp	Timestamp	1608518536265	The timestamp that indicates when the outlier instance was removed.

Recovery of outlier instance removal

The following example shows the event that EventBridge receives when outlier instance removal is recovered for an application:

{
    "specversion":"1.0",
    "subject":"",
    "source":"acs.mse",
    "data":{
        "framework":"DUBBO",
        "extraInfo":"172.28.XX.XX:26880 IsolationContext{isolationTimeMultiple=1, recoverTime=1608445705043}",
        "timestamp":1608445713989
    },
    "datacontenttype":"application/json",
    "type":"mse:Agent:OutlierRecover",
