Performance Co-Pilot (PCP) is a framework and set of services for supporting system-level performance monitoring and performance management. It provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data using a single API. A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts. Archive logging and replay are integrated so that a client application can use the same API to process real-time data from a host or historical data from an archive.
Sawmill is a log analysis tool which can be used to analyze Web site traffic, proxy usage, ftp usage, and much more. Major features include a persistent database for long-term tracking of statistics, hierarchical data mining features, and many security features appropriate for use in a multi-user environment.
NEPM monitors and reports uptime, critical events and their predecessors, access rates, bytes-served rates, and error rates for network node equipment. Hardware and software elements within the nodes are tracked and reported separately to make possible rapid fault isolation. It is a very general, highly configurable, two-part software system that captures and analyzes logged performance data from IP-networked equipment and reports it via email and Web pages. Current conditions and history from systems based on Windows NT/2000, Unix, and Unix-style operating systems can be tracked and reported. Most major server, switch and router systems can be monitored, without running agents on the target systems. NEPM itself is system-independent and can be hosted on either a Unix or Win NT system or a combination of these with equal ease.
LinkGrammar-WN is a lexicon expansion for the Link Grammar Parser. The Link Grammar Parser is a syntactic parser of the English language that is capable of handling a wide variety of syntactic constructions and is considered quite robust. The LinkGrammar-WN project aims to import lexical information from WordNet in an effort to increase the size of the LGP lexicon. This project is of interest to anyone interested in NLP (natural language parsing) of English text.
Snare for Apache provides a remote distribution facility for Apache Web server logs. It is known to run on most Unix variations, including Linux, Solaris, AIX, Tru64, and Irix. Snare for Apache can be used to send data to either a remote or local SYSLOG server, or the Snare Server for centralized collection, analysis, and archival.
nxlog is a modular, multi-threaded, high-performance log management solution with multi-platform support. In concept, it is similar to syslog-ng or rsyslog, but is not limited to Unix/syslog only. It can collect logs from files in various formats, receive logs from the network remotely over UDP, TCP, or TLS/SSL on all supported platforms. It supports platform-specific sources such as the Windows Eventlog, Linux kernel logs, Android device logs, local syslog, etc. Writing and reading logs to/from databases is also supported for many database servers. The collected logs can be stored into files, databases, or forwarded to a remote log server using various protocols. The old BSD Syslog and the newer IETF syslog standard (RFC 3164 and RFC 5424-5426) are fully supported by nxlog in addition to XML, JSON, CSV, GELF, and other custom formats. A key concept in nxlog is to be able to handle and preserve structured logs so there is no need to convert everything to syslog and then parse these logs again at the other side. It has powerful message filtering, log rewrite, and conversion capabilities. Using a lightweight, modular, and multi-threaded architecture which can scale, nxlog can process hundreds of thousands of events per second.
