The mysqlard daemon collects MySQL performance data in a round robin database using rrdtool. rrdtool stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density. The main goal of the package is to help the database system administrator in tuning the system for maximum performance. The package also contains example graphing, cron, and PHP scripts.
Objectrefenceanalyser is a framework that helps the user understand object/data correlations and their impact. It analyzes and traverses objects and their references during the runtime of any Java application using reflection or by importing data from a CSV-table. The results can be shared for remote access, persisted, or explored via diagrams and graphs in the GUI.
check_mysql runs as a daemon with a continuous connection to MySQL, watching the list of running SELECT queries. It enforces a timeout for queries: if a query runs too long, it is killed and a report including the query and EXPLAIN output are emailed. Its probably not something you'd want to use on a production system, but it is very useful during development and testing phases for finding, analyzing, and optimizing SQL queries.
Simple Log is a small library that does logging very simply and requires you to do almost nothing (other than actually logging) to get log output to happen. It is much simpler to use than a logging framework, especially in terms of configuration. It doesn't attempt to solve every logging problem in one package, but contains enough features to be a viable alternative for most applications that need logging. This tool will handle the logging needs of most small- to large-sized projects, but with an almost non-existent learning curve.
The DPML SDK is a management platform for Java-based component development, resource management, and deployment. It is composed of the Transit resource management layer, the Depot multi-project build system, the Metro component management runtime engine, and the Station application management console.
LogDistiller is a log files merge and sort tool. It reads log files, parses them into structured log events with attributes, then classifies them according to rules configured in an XML file. Classification results go into reports, which are published according to the rule configuration: simply stored in a file, sent by mail, or even added in a news feed. Some log parsers are included for syslog, Weblogic, simple line logs, Oracle alerts, and others. Log file parsing is designed to be easy to extend.
NoBug is a library which provides assertions, logging statements, and annotations for C and C++ programs. It includes pre-/post-condition and invariant checks, as well as generic assertions. Checks are enabled based on build-levels and scope tags. It also includes debugger support (valgrind), dumping of data structures, logging your application's activities, runtime customizable logging via environment variables, different logging targets (ringbuffer, stderr, syslog, debugger, etc.), and annotation of your source code regarding known bugs, things to do, and planned things. It can track resources and detect deadlocks.
