Restlight Endpoint扩展

业务线程池Metrics

Note

业务线程当前采用JUC的ThreadPoolExecutor实现，后续版本可能会换成自定义实现，因此Metrics内容可能发生变更

1、Json 格式

Get actuator/bizthreadpool

Example:

curl -X GET localhost:8080/actuator/bizthreadpool

{
    "corePoolSize": 4,
    "maxPoolSize": 4,
    "queueLength": 1024,
    "keepAliveTimeSeconds": 180,
    "activeCount": 1,
    "poolSize": 4,
    "largestPoolSize": 4,
    "taskCount": 6,
    "queueCount": 0,
    "completedTaskCount": 5
}

业务线程池扩缩容

Post actuator/bizthreadpool

curl -X POST -H "Content-Type:application/json" -d "{\"corePoolSize\":\"1\",\"maxPoolSize\":\"2\"}" localhost:8080/actuator/bizthreadpool

IO线程池Metrics

1、Json 格式

Get actuator/ioexecutor

Example:

curl -X GET localhost:8080/actuator/ioexecutor

{
    "childExecutors": [
        {
            "pendingTasks": 0,
            "maxPendingTasks": 2147483647,
            "ioRatio": 50,
            "taskQueueSize": 0,
            "tailTaskQueueSize": 0,
            "threadName": "Netty-I/O-1#0",
            "threadPriority": 5,
            "threadState": "RUNNABLE"
        },
        {
            "pendingTasks": 0,
            "maxPendingTasks": 2147483647,
            "ioRatio": 50,
            "taskQueueSize": 0,
            "tailTaskQueueSize": 0,
            "threadName": "Netty-I/O-1#1",
            "threadPriority": 5,
            "threadState": "RUNNABLE"
        }
    ],
    "threadCount": 2,
    "pendingTasks": 0,
    "threadStates": {
        "RUNNABLE": 2
    },
    "terminated": false,
    "shutDown": false
}

获取Restlight所有配置信息

强制Full GC

Post actuator/forcefgc

Example:

curl -X POST localhost:8080/actuator/forcefgc

修改优雅停机等待时间

Post actuator/terminationtimeout。

Example：

curl -X POST -H "Content-Type:application/json" -d "{\"timeout\": 120}" localhost:8080/actuator/terminationtimeout

Success
