Log4php is a PHP port of Log4j, the most popular Java logging framework. It supports configuration through XML and properties files (with the same structure as log4j) and custom Configurators. File, RollingFile, DailyFile, Echo, Console, Mail, PEAR::Db, PHP error, Syslog or NT events, and socket appenders are supported. Simple, TTCC, Pattern, Html, and Xml Layouts are supported. It also supports Filters, custom Levels, and Loggers. Internal debugging can be switched on and off. Log4php can be used inside a class or inside a main/sub function.
The Google Serial Graphics Adapter BIOS, or SGABIOS, provides a means for legacy x86 software to communicate with an attached serial console as if a video card were attached. It is designed to be inserted into a BIOS as an option ROM to provide over a serial port the display and input capabilities normally handled by a VGA adapter and a keyboard, and additionally provide hooks for logging displayed characters for later collection after an operating system boots. It is designed to handle all text mode output sent to the legacy video BIOS int 10h service routine. Int 10h is the most common method for displaying characters in 16-bit legacy x86 code.
OtrosLogViewer (OLV) is software for analyzing an application's logs and stack traces. It loads logs from remote servers using ftp, sftp, ssh, samba and other supported filesystems, listening on a socket, or connection to a Log4j SocketHubAppender. Logs can be gzipped, and OLV will decompress them on the fly. Many log formats are supported (JDK logging, Log4j XML, and custom patterns). OLV allows log highlighting. Automatic log highlighting is based on string matches, regular expressions, or custom Java code. Notes can be added to log events. Display of message details can be customized by message formatters and a colorizer (i.e., formating SOAP request and highlighting XML syntax). OLV can be extended by plugins (filters, log parsers, log event markers, message detail formatters, and colorizers).
