netframework_clrmemory collector

The netframework_clrmemory collector exposes metrics about memory in dotnet applications.

Metric name prefix	netframework_clrmemory
Classes	Win32_PerfRawData_NETFramework_NETCLRMemory
Enabled by default?	No

Flags

None

Metrics

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_heap_size_bytes	Displays the maximum bytes that can be allocated; it does not indicate the current number of bytes allocated.	gauge	process
windows_netframework_clrmemory_promoted_bytes	Displays the bytes that were promoted from the generation to the next one during the last GC. Memory is promoted when it survives a garbage collection.	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
windows_netframework_clrmemory_gc_time_percent	Displays the percentage of time that was spent performing a garbage collection in the last sample.	gauge	process
