~$ vim /apps/apache-skywalking-apm-bin/config/oal/core.oal
service_resp_time # 服务的响应时间
service_sla # 服务http请求成功率SLV，比如99%
service_cpm # 表示每分钟吞吐量
service_percentile # 指定响应时间百分比，即p99,p95,p75,p50的数据统计结果
service_apdex # 应用性能指数、// Endpoint scope metrics
endpoint_cpm # 端点每分钟吞吐量
endpoint_resp_time # 端点响应时间
endpoint_sla # 端点http请求成功率SLA，比如99%
endpoint_percentile # 端点的最近多少数据范围内的响应时间百分比，即p99,p95,p75统计结果
