nfslogsum(8) System Manager's Manual nfslogsum(8) NAME nfslogsum - Summarize nfswatch log file SYNOPSIS /usr/sbin/nfslogsum [-n] [-v] [logfile] FLAGS Directs nfslogsum to read only the first n entries in the log file. This is useful for summarizing log files in cumulative chunks. Pro- duces a verbose summary of the log file. DESCRIPTION The nfslogsum command summarizes log files produced by the nfswatch program. By default the log file nfswatch.log is summarized; an alter- nate log file can be specified on the command line. Each nfswatch log file may contain one or more log sessions, each indi- cated by a header which is printed when logging is turned on. For each log session, nfslogsum tallies up the interval packet totals and prints out a one-page summary of the log session. Total packets and percent- ages are tabulated for each category and displayed. In addition to the summary information printed as described above, a summary of how many calls to each NFS procedure were made on each file system and individual file will be printed. This summary information is divided into three sections of six columns each. The columns are headed by the names of the following NFS procedures: Does nothing. This procedure is provided to allow server response testing and timing. Gets the file attributes (type, mode, number of links, owner's uid, owner's gid, size, access, modification and change times, and others). This procedure is used by the stat(2) system call, as well as several others. Sets the file attributes (mode, owner's uid, owner's gid, size in bytes, access and modification times). This procedure is used by system calls such as chmod(2), chown(2), and truncate(2). Gets the file system root. This procedure is obsolete, and has been replaced by a MOUNT protocol procedure. Looks up the file name. This procedure is used to obtain an initial file handle for use in current and future re- quests on that file, and is used by many different system calls. Reads from the symbolic link. This procedure is used by the readlink system call and by the kernel. Reads data from the file. This procedure is used by the read(2) system call. Writes to the cache. Unused in the current NFS protocol revision. Writes data to a file. This procedure is used by the write(2) system call. Creates a file. This procedure is used by the creat(2) and open(2) system calls. Removes a file. This procedure is used by the unlink(2) system call. Renames a file. This procedure is used by the rename system call. Creates a link to the file. This procedure is used by the link'(2) system call. Creates a symbolic link to the file. This procedure is used by the symlink(2) system call. Creates a directory. This procedure is used by the mkdir(2) system call. Removes a directory. This procedure is used by the rmdir(2) system call. Reads entries from a directory. Generally only one READDIR call is needed per directory, since a variable number of entries can be returned. Gets file system attributes (transfer size, block size, blocks in use, blocks free). This procedure is used by the statfs(2) system call. RESTRICTIONS The nfslogsum utility is sensitive to the format of the log file pro- duced by nfswatch. Do not edit or change the log file before using it as input to nfslogsum. RELATED INFORMATION nfswatch(8), tcpdump(8), packetfilter(7), bpf(7) delim off nfslogsum(8)
