【问题描述】：
我正在使用 Spring Boot Actuator 依赖项来了解应用程序。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、总时间和最大值。
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
当我执行泛化表单时
localhost:8889/actuator/metrics/http.server.requests 我得到 MAX 为 3.00..
我也见过production-ready-features，但找不到任何关于如何计算 MAX 或它代表什么的描述
注意事项： 随着请求数量的增加，COUNT、TOTAL_TIME 也在增加，但 MAX 有时会减少（详见请求 1、请求 2）
请求 1：http.server.requests
{
"name": "http.server.requests",
"description": null,
"baseUnit": "seconds",
"measurements": [
{
"statistic": "COUNT",
"value": 597
},
{
"statistic": "TOTAL_TIME",
"value": 144.9057076
},
{
"statistic": "MAX",
"value": 3.0002913
}
],
"availableTags": [
{
"tag": "exception",
"values": [
"None"
]
},
{
"tag": "method",
"values": [
"GET"
]
},
{
"tag": "uri",
"values": [
"/actuator/metrics/{requiredMetricName}",
"/**/favicon.ico",
"/actuator",
"/user/getEmployee/{employeeId}",
"/user/asset/getAllAssets",
"/actuator/health",
"/actuator/info",
"/actuator/env/{toMatch}",
"/actuator/metrics",
"/**"
]
},
{
"tag": "outcome",
"values": [
"CLIENT_ERROR",
"SUCCESS"
]
},
{
"tag": "status",
"values": [
"404",
"200"
]
}
]
}
更新
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）
localhost:8889/actuator/metrics/http.server.requests?tag=uri:/user/getEmployee/{employeeId}
响应 400
localhost:8889/actuator/metrics/http.server.requests?tag=uri:/user/asset/getAllAssets
{
"name": "http.server.requests",
"description": null,
"baseUnit": "seconds",
"measurements": [
{
"statistic": "COUNT",
"value": 1
},
{
"statistic": "TOTAL_TIME",
"value": 0.8311609
},
{
"statistic": "MAX",
"value": 0
}
],
"availableTags": [
{
"tag": "exception",
"values": [
"None"
]
},
{
"tag": "method",
"values": [
"GET"
]
},
{
"tag": "outcome",
"values": [
"SUCCESS"
]
},
{
"tag": "status",
"values": [
"200"
]
}
]
}
请求 2：http.server.requests
localhost:8889/actuator/metrics/http.server.requests
{
"name": "http.server.requests",
"description": null,
"baseUnit": "seconds",
"measurements": [
{
"statistic": "COUNT",
"value": 3346
},
{
"statistic": "TOTAL_TIME",
"value": 559.7992767999998
},
{
"statistic": "MAX",
"value": 2.3612968
}
],

你能检查一下
localhost:8889/actuator/metrics/http.server.requests?tag=uri:/user/getEmployee/{employeeId}和localhost:8889/actuator/metrics/http.server.requests?tag=uri:/user/asset/getAllAssets吗，它们应该和MAX = 0的那个屏幕一样。否则，您会看到带有根调用的所有端点的指标聚合。 -
感谢@buræquete 的回复，
/user/getEmployee/{employeeId}我得到404,400和uri:/user/asset/getAllAssets相同的结果MAX as 0 -
@buræquete 随着请求数量的增加，COUNT，TOTAL_TIME 也在增加，但 MAX 有时会减少（请参阅请求 1，请求 2 了解详细信息），您能告诉我如何MAX是计算出来的还是代表什么，谢谢
