Prometheus (prometheus
)
这prometheus
endpoint 以 Prometheus 服务器抓取所需的格式提供 Spring Boot 应用程序的指标。
检索所有指标
要检索所有指标,请创建一个GET
request 添加到/actuator/prometheus
,如以下基于 curl 的示例所示:
$ curl 'http://localhost:8080/actuator/prometheus' -i -X GET
生成的响应类似于以下内容:

默认响应内容类型为text/plain;version=0.0.4
.
端点还可以生成application/openmetrics-text;version=1.0.0
当使用适当的Accept
header,如以下基于 curl 的示例所示:
$ curl 'http://localhost:8080/actuator/prometheus' -i -X GET \
-H 'Accept: application/openmetrics-text; version=1.0.0; charset=utf-8'
