OpenAFS                                            2025-03-21                                FS_GETCACHEPARMS(1)

       The fsgetcacheparms command displays the current size of the cache (which can be in memory or on disk),
       and the amount currently in use.

       The reported statistics are from kernel memory, so the reported size can differ from the setting
       specified in the /etc/openafs/cacheinfo file on a machine using a disk cache, if the fssetcachesize
       command has been used to alter cache size.

       The following example shows the output on a machine with a 25000 kilobyte cache.

          % fs getcacheparms
          AFS using 22876 of the cache's available 25000 1K byte blocks.

       The following shows the output when asked to show file information.

          % fs getcacheparm -files
          AFS using     0% of cache blocks (897 of 200000 1k blocks)
                        1% of the cache files (79 of 6250 files)

       And finally, the following detailed information can be obtained by using the excessive flag

          % fs getcacheparm -excessive
          AFS using     0% of cache blocks (897 of 200000 1k blocks)
                        1% of the cache files (79 of 6250 files)

-help
           Prints the online help for this command. All other valid options are ignored.

       -files
           Displays  the  current number of cache files in use, and the maximum available, as well as displaying
           the current cache size.

       -excessive
           Displays detailed cache  statistics,  including  the  flags  set  on  each  cache  element,  and  the
           distribution of cache entries by size.

       The output reports

          AFS using <amount> of the cache's available <size> 1K byte blocks.

       where  <amount> is the number of kilobyte blocks currently used to cache data and status information, and
       <size> is the total current cache size.

       None
