NAME
apachetop - display real-time web server statistics SYNOPSIS
apachetop [-f filename] [-H hits | -T time] [-q] [-l] [-s segments] [-p] [-r secs] DESCRIPTION
ApacheTop watches a logfile generated by Apache (in standard common or combined logformat, and generates human-parsable output in realtime. OPTIONS
-f logfile Select which file to watch. Specify this option multiple times to watch multiple files. -H hits | -T time These options are mutually exclusive. Specify only one, if any at all. They work as follows. ApacheTop maintains a table of informa- tion internally containing all the relevant information about the hits it's seen. This table can only be a finite size, so you need to decide how big it's going to be. You have two options. You can either: Use -H to say "remember <this many> hits" or Use -T to say "remember all hits in <this many> seconds" The default (at the moment) is to remember hits for 30 seconds. Setting this too large (whichever option you choose) will cause ApacheTop to use more memory and more CPU time. My experimentation finds that remem- bering no more than around 5000 requests works well. -q Instructs ApacheTop to keep the querystrings, not remove them. -l Instructs ApacheTop to lowercase all URLs, thus /FOO and /foo are treated as the same and accumulate the same statistics. -s segments Instructs ApacheTop to only keep the first <segments> parts of the path. Trailing slashes are kept if present. Statistics are then merged for each truncated url. -p Instructs ApacheTop to keep the protocol (http:// usually) at the front of its' referrer strings. Normal behaviour is to remove them to give more room to more useful information. -r secs Set default refresh delay, in seconds. EXAMPLES
apachetop -f /var/logs/httpd/access.log AUTHOR

NAME
cachefsstat - Cache File System statistics SYNOPSIS
/usr/bin/cachefsstat [-z] [path...] DESCRIPTION
The cachefsstat command displays statistical information about the cache file system mounted on path. The statistical information includes cache hits and misses, consistency checking, and modification operations. If path is not specified, all mounted cache file systems are used. cachefsstat can also be used to reinitialize this information (see -z option). The statistical information has the following format: <cache hit rate> <consistency checks> <modifies> where: hit rate The percentage of cache hits over the total number of attempts, followed by the actual numbers of hits and misses. consistency checks The number of consistency checks performed, followed by the number that passed, and the number that failed. modifies The number of modify operations, including writes, creates, etc. OPTIONS
The following option is supported: -z Zero (reinitialize) statistics. Execute cachefsstat -z before executing cachefsstat again to gather statistics on the cache per- formance. This option can only be use by the superuser. The statistics printed reflect those just before the statistics are reinitialized. USAGE
See largefile(5) for the description of the behavior of cachefsstat when encountering files greater than or equal to 2 Gbyte (2**31 bytes). EXAMPLES
Example 1: Using cachefsstat The following example shows the cachefsstat command run on file system /test: example# cachefsstat /test /test cache hit rate: 100% (0 hits, 0 misses) consistency checks: 0 (0 pass, 0 fail) modifies: 0 garbage collection: 0 EXIT STATUS
The following exit values are returned: 0 Successful completion. non-zero An error occurred. ATTRIBUTES
