I've spent a long time but haven't found the metric name for the active count of Tomcat threads. The metric name "meter_thread_pool_active_size-tomcat_execute_pool" found in search posts is incorrect, and SkyWalking throws an error when starting. Could you help point out where the specific documentation is? |

How can I tell the specific name from the edit function? I've tried many combinations similar to "meter_thread_pool_active_size-tomcat_execute_pool", but none of them work.

It works if I write it like this: meter_thread_pool{metric_type='active_size',pool_name='tomcat_execute_pool'}. Thank you very much for your help. :) |

This is a labeled metric. You don't need any combination. The metric name is
meter_thread_pool. You need to pick the label key/value in the expression you use in the alerting rule setups.e.g.
metric_name{key='value'}
