NAME
Polygraph - performance benchmark for web intermediaries DESCRIPTION
Web Polygraph is a performance testing tool for caching proxies, origin server accelerators, L4/7 switches, content filters, and other Web intermediaries. Polygraph's features include: * high-performance HTTP clients and servers * realistic HTTP, FTP, and SSL traffic generation * HTTP Basic, NTLM, and Negotiate proxy authentication * LDAP-friendly generation of user credentials * flexible content simulation * ready-to-use standard workloads for benchmarking * powerful domain-specific configuration language * portable open-source implementation * friendly commercial support Web Polygraph consists of many tools listed below. See individual man pages for more information. Detailed documentation is available at www.web-polygraph.org. polygraph-aka - IP aliases manipulation tool polygraph-beepmon - forwards BEEP messages to an external program polygraph-cdb - content database manipulation tool polygraph-client - Web Polygraph client simulator polygraph-cmp-lx - log comparison tool polygraph-distr-test - distribution test polygraph-dns-cfg - DNS server configuration tool polygraph-lr - console log extractor polygraph-ltrace - trace extractor polygraph-lx - stats extractor polygraph-pgl2acl - translates PGL access rules into Squid Proxy ACLs polygraph-pgl2eng - PGL to English converter polygraph-pgl2ips - PGL IP addresses calculator polygraph-pgl2ldif - LDIF (and other text-based) configuration generator polygraph-pgl-test - PGL validator polygraph-pmix2-ips - PolyMix-2 address calculator polygraph-pmix3-ips - PolyMix-3 address calculator polygraph-polymon - interactive test monitoring tool polygraph-polyprobe - tests TCP throughput in a full client/server mesh polygraph-polyrrd - supplies run-time Polygraph stats to RRDtool polygraph-pop-test - predicts cache hit ratios for a given workload polygraph-reporter - HTML report generator polygraph-rng-test - random number generator test polygraph-server - Web Polygraph server simulator polygraph-udp2tcpd - converts UDP monitoring messages into a TCP stream read by polymon polygraph-webaxe4-ips - WebAxe-4 address calculator COPYRIGHT

NAME
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 10.0.0.1:access_log.1 10.0.0.2:access_log.2 mergelogs -p pen.log 10.0.18.6:access_log-10.0.18.6 10.0.18.8:access_log-10.0.18.8 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
