Spring Boot, Micrometer, Prometheus, Grafana - 计算 TPS 和平均执行时间，怎么写 PromQL？

[JasonLaw]

我的 Spring Boot 应用暴露了下面这些 metrics ，我想计算MsgProcessor.process的 TPS 和平均执行时间，请问怎么写 PromQL ？

# HELP MsgProcessor_process_seconds_max  
# TYPE MsgProcessor_process_seconds_max gauge
MsgProcessor_process_seconds_max{application="out-adaptor",class="MsgProcessor",exception="none",method="process",} 0.0
# HELP MsgProcessor_process_seconds  
# TYPE MsgProcessor_process_seconds summary
MsgProcessor_process_seconds_count{application="out-adaptor",class="MsgProcessor",exception="none",method="process",} 13237.0
MsgProcessor_process_seconds_sum{application="out-adaptor",class="MsgProcessor",exception="none",method="process",} 2.735527137

By the way ，我是参考Spring Boot app metrics - with Prometheus and Micrometer - Tutorial Works实现的。
