|FS_GETCACHEPARMS(1)||AFS Command Reference||FS_GETCACHEPARMS(1)|
NAME¶fs_getcacheparms - Displays the current size and usage of the cache
SYNOPSIS¶fs getcacheparms [-help] [-files] [-excessive]
fs getca [-h] [-files] [-excessive]
DESCRIPTION¶The fs getcacheparms 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 fs setcachesize command has been used to alter cache size.
- Prints the online help for this command. All other valid options are ignored.
- Displays the current number of cache files in use, and the maximum available, as well as displaying the current cache size.
- Displays detailed cache statistics, including the flags set on each cache element, and the distribution of cache entries by size.
OUTPUT¶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.
EXAMPLES¶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) afs_cacheFiles: 6250 IFFree: 6171 IFEverUsed: 79 IFDataMod: 0 IFDirtyPages: 0 IFAnyPages: 0 IFDiscarded: 1 DCentries: 3122 0k- 4K: 74 4k- 16k: 3045 16k- 64k: 2 64k- 256k: 0 256k- 1M: 1 >=1M: 0
