pagefile collector

The pagefile collector exposes metrics about the pagefile usage

Metric name prefix	pagefile
Data source	Performance counter Paging File (% Usage and its base), GetPerformanceInfo (page size)
Enabled by default?	No

Flags

None

Metrics

Name	Description	Type	Labels
windows_pagefile_free_bytes	Number of bytes that can be mapped into the operating system paging files without causing any other pages to be swapped out	gauge	file
windows_pagefile_limit_bytes	Current size of the paging file in bytes	gauge	file

Both values come from the % Usage counter: its raw value is the number of pages in use and its base is the size of the paging file in pages. They are multiplied by the system page size. A paging file without a valid size is left out.

Example metric

# HELP windows_pagefile_free_bytes Number of bytes that can be mapped into the operating system paging files without causing any other pages to be swapped out
# TYPE windows_pagefile_free_bytes gauge
windows_pagefile_free_bytes{file="C:\\pagefile.sys"} 6.025797632e+09
# HELP windows_pagefile_limit_bytes Current size of the paging file in bytes
# TYPE windows_pagefile_limit_bytes gauge
windows_pagefile_limit_bytes{file="C:\\pagefile.sys"} 6.442450944e+09
