skywalking tomcat threadpool alarm not work

[liu729133700]

version 9.4.0

tomcat_thread_pool_active_alarm_rule:
metrics-name: meter_thread_pool_active_size-tomcat_execute_pool
op: ">"
threshold: 1
period: 1
count: 1
silence-period: 0
message: instance {name} tomcat thread pool active size over 1.

This is one of my alarm configuration items.I used the jmeter tool to raise the instance active_size-tomcat_execute_pool indicator to 8, but the alarm did not work.I suspect that metrics-name is incorrectly configured

Period 1 is not working. You should have a larger window.

tomcat_thread_pool_active_alarm_rule:
metrics-name: meter_thread_pool_active_size-tomcat_execute_pool
op: ">"
threshold: 2
period: 5
count: 1
silence-period: 5
message: 实例 {name} tomcat活跃线程数已超过 1.

I modified the period configuration entry but it still didn't trigger the alarm

Isn't this labeled metric? How your config works foe this?

I believe you should use 10.0.1 and learn mqe in altering.
