Description
This Collector provides Poco::ThreadPool specific metrics:
- poco_threadpool_max_threads: Maximum number of threads available in the thread pool (capacity).
- poco_threadpool_used_threads: Number of currently used threads.
- poco_threadpool_allocated_threads: Number of currently allocated threads.
Metrics have a single label "name" identifying the thread pool. The name of the default thread pool is "default".
