The task manager exposes metrics for underlying thread pools and jobs processing duration and count.

Metric	Type	Tags	Description
`corda_taskmanager_executor_active_threads`	Gauge	`name`	The approximate number of threads that are actively executing tasks.
`corda_taskmanager_executor_completed_tasks_total`	Counter	`name`	The approximate number of tasks that have completed execution.
`corda_taskmanager_executor_idle_seconds_count`	Counter	`name`	The number of events that have been observed for the base metric.
`corda_taskmanager_executor_idle_seconds_max`	Gauge	`name`	The maximum observed value for the base metric.
`corda_taskmanager_executor_idle_seconds_sum`	Counter	`name`	The total sum of all observed values for the base metric.
`corda_taskmanager_executor_pool_core_threads`	Gauge	`name`	The core number of threads for the pool.
`corda_taskmanager_executor_pool_max_threads`	Gauge	`name`	The maximum allowed number of threads in the pool.
`corda_taskmanager_executor_pool_size_threads`	Gauge	`name`	The current number of threads in the pool.
`corda_taskmanager_executor_queue_remaining_tasks`	Gauge	`name`	The number of additional elements that this queue can ideally accept without blocking.
`corda_taskmanager_executor_queued_tasks`	Gauge	`name`	The approximate number of tasks that are queued for execution.
`corda_taskmanager_executor_scheduled_repetitively_total`	Counter	`name`
`corda_taskmanager_executor_seconds_count`	Counter	`name`	The number of events that have been observed for the base metric.
`corda_taskmanager_executor_seconds_max`	Gauge	`name`	The maximum observed value for the base metric.
`corda_taskmanager_executor_seconds_sum`	Counter	`name`	The total sum of all observed values for the base metric
`corda_taskmanager_completion_time_count`	Counter	`task.manager.name` `task.type`	The number of tasks completed by a task manager.
`corda_taskmanager_completion_time_max`	Gauge	`task.manager.name` `task.type`	The maximum time taken to complete a task by a task manager.
`corda_taskmanager_completion_time_sum`	Counter	`task.manager.name` `task.type`	The total sum of the time taken to execute all completed tasks by a task manager.
`task_manager_live_tasks`	Gauge	`task.manager.name` `task.type`	The number of live tasks running or scheduled in the task manager.
