Is there a way to track memory in armeria server?

See original GitHub issue

Hello, I am wondering there is a way to track memory state of armeria server? I found default armeria metrics, something like that:

# HELP armeria_executor_queued_tasks The approximate number of tasks that are queued for execution
# TYPE armeria_executor_queued_tasks gauge
armeria_executor_queued_tasks{name="blockingTaskExecutor",} 0.0
# HELP armeria_executor_queue_remaining_tasks The number of additional elements that this queue can ideally accept without blocking
# TYPE armeria_executor_queue_remaining_tasks gauge
armeria_executor_queue_remaining_tasks{name="blockingTaskExecutor",} 2.147483647E9
# HELP armeria_executor_idle_seconds  
# TYPE armeria_executor_idle_seconds summary
armeria_executor_idle_seconds_count{name="blockingTaskExecutor",} 0.0
armeria_executor_idle_seconds_sum{name="blockingTaskExecutor",} 0.0
# HELP armeria_executor_idle_seconds_max  
# TYPE armeria_executor_idle_seconds_max gauge
armeria_executor_idle_seconds_max{name="blockingTaskExecutor",} 0.0
# HELP armeria_executor_pool_size_threads The current number of threads in the pool
# TYPE armeria_executor_pool_size_threads gauge
armeria_executor_pool_size_threads{name="blockingTaskExecutor",} 0.0

but it seems that all of them shows unrealistic results

armeria_server_active_requests is a snapshot of currently running services. If your service ends in a short time, it would not be recorded. https://github.com/line/armeria/blob/c8d1f5ef142f65fd79bd01b87d8155d220c9d0b9/core/src/main/java/com/linecorp/armeria/internal/common/metric/RequestMetricSupport.java#L84-L88

If you are not familiar with the metrics of Micrometer, you may want to see the following example: https://github.com/line/centraldogma/blob/ed507c70c9e25cfaff4bee25050aca06b12b4843/server/src/main/java/com/linecorp/centraldogma/server/CentralDogma.java#L784-L792
