mergelogs - merge and consolidate web server logs SYNOPSIS
mergelogs -p penlog [-c] [-d] [-j jitter] [-t seconds] server1:logfile1 [server2:logfile2 ...] EXAMPLES
mergelogs -p pen.log mergelogs -p pen.log DESCRIPTION
When pen is used to load balance web servers, the web server log file lists all accesses as coming from the host running pen. This makes it more difficult to analyze the log file. To solve this, pen creates its own log file, which contains the real client address, the time of the access, the target server address and the first few bytes of the requests. Mergelogs reads pen's log file and the log files of all load balanced web servers, compares each entry and creates a combined log file that looks as if the web server cluster were a single physical server. Client addresses are replaced with the real client addresses. In the event that no matching client address can be found in the pen log, the server address is used instead. This should never happen, and is meant as a debugging tool. A large number of these indicates that the server system date needs to be set, or that the jitter value is too small. You probably don't want to use this program. Penlog is a much more elegant and functional solution. OPTIONS
-c Do not cache pen log entries. The use of this option is not recommended, as it will make mergelogs search the entire pen log for every line in the web server logs. -d Debugging (repeat for more). -p penlog Log file from pen. -j jitter Jitter in seconds (default 600). This is the maximum variation in time stamps in the pen and web server log files. A smaller value will result in a smaller pen log cache and faster processing, at the risk of missed entries. -t seconds The difference in seconds between the time on the pen server and UTC. For example, this is 7200 (two hours) in Finland. server:logfile Web server address and name of log file. AUTHOR

nislog - display the contents of the NIS+ transaction log SYNOPSIS
/usr/sbin/nislog [-h num | -t num] [-v] [directory...] DESCRIPTION
nislog displays the contents of the NIS+ server transaction log on the standard output. This command can be used to track changes in the namespace. The /var/nis/trans.log file contains the transaction log maintained by the NIS+ server. When updates occur, they are logged to this file and then propagated to replicas as log transactions. When the log is checkpointed, updates that have been propagated to the replicas are removed. The nislog command can only be run on an NIS+ server by superuser. It displays the log entries for that server only. If directory is not specified, the entire log is searched. Otherwise, only those logs entries that correspond to the specified directories are displayed. OPTIONS
-h num Display num transactions from the ``head'' of the log. If the numeric parameter is 0, only the log header is displayed. -t num Display num transactions from the ``tail'' of the log. If the numeric parameter is 0, only the log header is displayed. -v Verbose mode. FILES
