memory collector

The memory collector exposes metrics about system memory usage

Metric name prefix	memory
Data source	Perflib
Classes	Win32_PerfRawData_PerfOS_Memory
Enabled by default?	Yes

Flags

None

Metrics

Name	Description	Type	Labels
windows_cs_logical_processors	Number of installed logical processors	gauge	None
windows_cs_physical_memory_bytes	Total installed physical memory	gauge	None
windows_memory_available_bytes	The amount of physical memory immediately available for allocation to a process or for system use. It is equal to the sum of memory assigned to the standby (cached), free and zero page lists	gauge	None
windows_memory_cache_bytes	Number of bytes currently being used by the file system cache	gauge	None
windows_memory_cache_bytes_peak	Maximum number of CacheBytes after the system was last restarted	gauge	None
windows_memory_cache_faults_total	Number of faults which occur when a page sought in the file system cache is not found there and must be retrieved from elsewhere in memory (soft fault) or from disk (hard fault)	gauge	None
windows_memory_commit_limit	Amount of virtual memory, in bytes, that can be committed without having to extend the paging file(s)	gauge	None
windows_memory_committed_bytes	Amount of committed virtual memory, in bytes	gauge	None
windows_memory_demand_zero_faults_total	The number of zeroed pages required to satisfy faults. Zeroed pages, pages emptied of previously stored data and filled with zeros, are a security feature of Windows that prevent processes from seeing data stored by earlier processes that used the memory space	gauge	None
windows_memory_free_and_zero_page_list_bytes	Not yet documented	gauge	None
windows_memory_free_system_page_table_entries	Number of page table entries not being used by the system	gauge	None
windows_memory_modified_page_list_bytes	Not yet documented	gauge	None
windows_memory_page_faults_total	Overall rate at which faulted pages are handled by the processor	gauge	None
windows_memory_swap_page_reads_total	Number of disk page reads (a single read operation reading several pages is still only counted once)	gauge	None
windows_memory_swap_pages_read_total	Number of pages read across all page reads (ie counting all pages read even if they are read in a single operation)	gauge	None
windows_memory_swap_pages_written_total	Number of pages written across all page writes (ie counting all pages written even if they are written in a single operation)	gauge	None
windows_memory_swap_page_operations_total	Total number of swap page read and writes (PagesPersec)	gauge	None
windows_memory_swap_page_writes_total	Number of disk page writes (a single write operation writing several pages is still only counted once)	gauge	None
windows_memory_pool_nonpaged_allocs_total	The number of calls to allocate space in the nonpaged pool. The nonpaged pool is an area of system memory area for objects that cannot be written to disk, and must remain in physical memory as long as they are allocated	gauge	None
windows_memory_pool_nonpaged_bytes_total	Number of bytes in the non-paged pool	gauge	None
windows_memory_pool_paged_allocs_total	Number of calls to allocate space in the paged pool, regardless of the amount of space allocated in each call	gauge	None
windows_memory_pool_paged_bytes	Number of bytes in the paged pool	gauge	None
windows_memory_pool_paged_resident_bytes	Not yet documented	gauge	None
windows_memory_standby_cache_core_bytes	Not yet documented	gauge	None
windows_memory_standby_cache_normal_priority_bytes	Not yet documented	gauge	None
windows_memory_standby_cache_reserve_bytes	Not yet documented	gauge	None
windows_memory_system_cache_resident_bytes	Not yet documented	gauge	None
windows_memory_system_code_resident_bytes	Not yet documented	gauge	None
windows_memory_system_code_total_bytes	Not yet documented	gauge	None
windows_memory_system_driver_resident_bytes	Not yet documented	gauge	None
windows_memory_system_driver_total_bytes	Not yet documented	gauge	None
windows_memory_transition_faults_total	Not yet documented	gauge	None
windows_memory_transition_pages_repurposed_total	Not yet documented	gauge	None
windows_memory_write_copies_total	The number of page faults caused by attempting to write that were satisfied by copying the page from elsewhere in physical memory	gauge	None
