Metrics

CLR Exceptions

Name	Description	Type	Labels
windows_netframework_clrexceptions_exceptions_thrown_total	Displays the total number of exceptions thrown since the application started. This includes both .NET exceptions and unmanaged exceptions that are converted into .NET exceptions.	counter	process

CLR Interop

Name	Description	Type	Labels

windows_netframework_clrinterop_interop_stubs_created_total	Displays the current number of stubs created by the common language runtime. Stubs are responsible for marshaling arguments and return values from managed to unmanaged code, and vice versa, during a COM interop call or a platform invoke call.	counter	process

CLR JIT

windows_netframework_clrloading_assemblies_loaded_total	Displays the total number of assemblies loaded since the application started. If the assembly is loaded as domain-neutral from multiple application domains, this counter is incremented only once.	counter	process
windows_netframework_clrloading_classes_loaded_total	Displays the cumulative number of classes loaded in all assemblies since the application started.	counter	process
windows_netframework_clrloading_class_load_failures_total	Displays the peak number of classes that have failed to load since the application started.	counter	process

CLR Locks and Threads

Name	Description	Type	Labels
windows_netframework_clrlocksandthreads_current_queue_length	Displays the total number of threads that are currently waiting to acquire a managed lock in the application.	gauge	process
windows_netframework_clrlocksandthreads_current_logical_threads	Displays the number of current managed thread objects in the application. This counter maintains the count of both running and stopped threads.	gauge	process
windows_netframework_clrlocksandthreads_physical_threads_current	Displays the number of native operating system threads created and owned by the common language runtime to act as underlying threads for managed thread objects. This counter's value does not include the threads used by the runtime in its internal operations; it is a subset of the threads in the operating system process.	gauge	process
windows_netframework_clrlocksandthreads_recognized_threads_current	Displays the number of threads that are currently recognized by the runtime. These threads are associated with a corresponding managed thread object. The runtime does not create these threads, but they have run inside the runtime at least once.	gauge	process
windows_netframework_clrlocksandthreads_recognized_threads_total	Displays the total number of threads that have been recognized by the runtime since the application started. These threads are associated with a corresponding managed thread object. The runtime does not create these threads, but they have run inside the runtime at least once.	counter	process
windows_netframework_clrlocksandthreads_queue_length_total	Displays the total number of threads that waited to acquire a managed lock since the application started.	counter	process
windows_netframework_clrlocksandthreads_contentions_total	Displays the total number of times that threads in the runtime have attempted to acquire a managed lock unsuccessfully.	counter	process

CLR Memory

Name	Description	Type	Labels
windows_netframework_clrmemory_allocated_bytes_total	Displays the total number of bytes allocated on the garbage collection heap.	counter	process
windows_netframework_clrmemory_finalization_survivors	Displays the number of garbage-collected objects that survive a collection because they are waiting to be finalized.	gauge	process

windows_netframework_clrmemory_number_gc_handles	Displays the current number of garbage collection handles in use. Garbage collection handles are handles to resources external to the common language runtime and the managed environment.	gauge	process
windows_netframework_clrmemory_collections_total	Displays the number of times the generation objects are garbage collected since the application started.	counter	process
windows_netframework_clrmemory_induced_gc_total	Displays the peak number of times garbage collection was performed because of an explicit call to GC.Collect.	counter	process
windows_netframework_clrmemory_number_pinned_objects	Displays the number of pinned objects encountered in the last garbage collection.	gauge	process
windows_netframework_clrmemory_number_sink_blocksinuse	Displays the current number of synchronization blocks in use. Synchronization blocks are per-object data structures allocated for storing synchronization information. They hold weak references to managed objects and must be scanned by the garbage collector.	gauge	process
windows_netframework_clrmemory_committed_bytes	Displays the amount of virtual memory, in bytes, currently committed by the garbage collector. Committed memory is the physical memory for which space has been reserved in the disk paging file.	gauge	process
windows_netframework_clrmemory_reserved_bytes	Displays the amount of virtual memory, in bytes, currently reserved by the garbage collector. Reserved memory is the virtual memory space reserved for the application when no disk or main memory pages have been used.	gauge	process
