弹簧启动执行器-MAX属性 [英] Spring Boot Actuator - MAX property
问题描述
我正在使用Spring Boot Actuator依赖项来获取应用程序的见解.为此，我使用了Spring Boot Admin.客户端服务器的配置工作正常.我必须测量要执行的端点的计数，总时间，最大值.
I am using Spring Boot Actuator dependency to get insights of application. For that, I have used Spring Boot Admin. Configuration for client-server is working fine. I have to measure the count, total-time, max for endpoints which are going to execute.
uri:/user/asset/getAllAssets
TOTAL_TIME: 831ms
MAX: 0ms
uri:/user/getEmployee/{employeeId}
TOTAL_TIME: 98ms
MAX: 0ms
为什么MAX(时间)为0而TOTAL_TIME:为Xms
Why MAX (time) is 0 while TOTAL_TIME: is Xms
我执行概括形式
localhost:8889/actuator/metrics/http.server.requests 我得到的 MAX为3.00 ..
localhost:8889/actuator/metrics/http.server.requests I get the MAX as 3.00..
I had also seen production-ready-features but not able to find any description about how MAX is calculated or what does it represent
注意: 随着请求数量的增加(COUNT个)，TOTAL_TIME也有所增加，但MAX有时会减少 (有关详细信息，请参见请求1，请求2)
Notes: with the number of request in an increase, COUNT, TOTAL_TIME is also getting an increase but MAX is reducing sometimes (see Request 1, Request 2 for details)

UPDATE
localhost:8889/actuator/metrics/http.server.requests?tag=uri:/user/getEmployee/2
localhost:8889/actuator/metrics/http.server.requests?tag=uri:/user/getEmployee/2
响应404 (我在请求执行器之前已经执行了/user/getEmployee/2)

推荐答案
- MAX代表什么
- What does MAX represent
MAX表示执行端点所需的最长时间.
MAX represents the maximum time taken to execute endpoint.
/user/asset/getAllAssets
COUNT TOTAL_TIME MAX
5 115 17
6 122 17 (Execution Time = 122 - 115 = 17)
7 131 17 (Execution Time = 131 - 122 = 17)
8 187 56 (Execution Time = 187 - 131 = 56)
9 204 56 From Now MAX will be 56 (Execution Time = 204 - 187 = 17)
- 如果对特定端点的请求数(或1个请求)减少，MAX将为0吗?
- Will MAX be 0 if we have less number of request (or 1 request) to the particular endpoint?
- 当MAX为0时
对特定端点的请求数量不影响MAX
No number of request for particular endPoint does not affect the MAX
为此，我采取了6个样本(对同一端点执行了6次).为此，我确定了调用端点的时间-MAX设置为零的时间之间的时间差
For that, I have taken 6 samples (executed the same endpoint for 6 times). For that, I have determined the time difference between the time of calling the endpoint - time for when MAX set back to zero
DistributionStatisticConfig has .expiry(Duration.ofMinutes(2)).bufferLength(3)
which sets some measurements to 0 if there is no request has been made in between expiry time or rotate time.
MAX 属性属于
公共静态最终统计信息 MAX
记录的最大数量.当这代表一个时间时，它是
报告监视系统的基本时间单位. The maximum amount recorded. When this represents a time, it is
reported in the monitoring system's base unit of time.
注释:
这是来自特定端点(此处为
Notes:
This is the cases from metric for a particular endpoint (here 用于 从请求1，请求2(有问题的)中可以看到，MAX减少了(从3.0002913减少到2.3612968)由于一个计时器.在我看来， As you can see from Request 1, Request 2 (in question) the MAX has been reduced (from 3.0002913 to 2.3612968) so that maybe because of MAX for some endPoint will be set backed to 0 due to a timer. In my view for MAX for 这篇关于弹簧启动执行器-MAX属性的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
