> Collect and monitor the thread pool performance Metrics exposed by DynamicTp actuator.
|
|
|
|
## PreRequisites
|
|
|
|
1. Integration Using `DynamicTp`
|
|
|
|
`DynamicTp` is a lightweight dynamic thread pool based on the configuration center of the Jvm language. It has built-in monitoring and alarm functions, which can be realized through SPI custom extensions.
|
|
|
|
For integrated use, please refer to the document [Quick Start](https://dynamictp.cn/guide/use/quick-start.html)
|
|
|
|
2. Open SpringBoot Actuator Endpoint to expose `DynamicTp` Metric interface
|
|
|
|
```yaml
|
|
management:
|
|
endpoints:
|
|
web:
|
|
exposure:
|
|
include: '*'
|
|
```
|
|
|
|
Test whether the access Metric interface `ip:port/actuator/dynamic-tp` has response json data as follows:
|
|
|
|
```json
|
|
[
|
|
{
|
|
"poolName": "commonExecutor",
|
|
"corePoolSize": 1,
|
|
"maximumPoolSize": 1,
|
|
"queueType": "LinkedBlockingQueue",
|
|
"queueCapacity": 2147483647,
|
|
"queueSize": 0,
|
|
"fair": false,
|
|
"queueRemainingCapacity": 2147483647,
|
|
"activeCount": 0,
|
|
"taskCount": 0,
|
|
"completedTaskCount": 0,
|
|
"largestPoolSize": 0,
|
|
"poolSize": 0,
|
|
"waitTaskCount": 0,
|
|
"rejectCount": 0,
|
|
"rejectHandlerName": null,
|
|
"dynamic": false,
|
|
"runTimeoutCount": 0,
|
|
"queueTimeoutCount": 0
|
|
},
|
|
{
|
|
"maxMemory": "4GB",
|
|
"totalMemory": "444MB",
|
|
"freeMemory": "250.34 MB",
|
|
"usableMemory": "3.81GB"
|
|
}
|
|
]
|
|
```
|
|
|
|
3. Add DynamicTp monitoring under HertzBeat middleware monitoring
