CLIChart is intended for quick summarization and visualization of data, especially from system logs. It provides tools to extract and manipulate tabular summary data from text files, and to generate and view simple charts from tabular data on the command line. Charts can be displayed in a window and/or saved.
Logsend is a Unix daemon for email notification of log file changes, having 3 different backends. It watches the log files and periodically mails you the additions (being able to filter them). Logsend comes with a dialog-based configuration tool, as well as a live monitor that allows the users to watch the changes in real time.
Logapp is a wrapper utility that helps supervise the execution of applications that produce heavy console output (e.g. make, CVS, and Subversion). It does this by logging, trimming, and coloring each line of the output before displaying it. It can be called instead of the executable that should be monitored; it then starts the application and logs all of its console output to a file. The output shown in the terminal is preprocessed, e.g. to limit the length of printed lines and to show the stderr output in a different color. It is also possible to automatically highlight lines that match a certain regular expression. The output is therefore reduced to the necessary amount, and all important lines are easy to identify.
mod_log_dbd is a module for Apache 2.2+ that writes access logs to a database using the APR DBD framework. It's designed for simplicity and speed, and therefore lacks some of the features of other logging modules. It does, however, automatically create any needed tables and columns.
SiLK (System for Internet-Level Knowledge) consists of two sets of tools: a packing system and an analysis suite. The packing system receives Netflow V5 PDUs or IPFIX and converts them into a more space efficient format, recording the packed records into service-specific binary flat files. The analysis suite consists of tools that can read these flat files and then perform various query operations, ranging from per-record filtering to statistical analysis of groups of records. The analysis tools interoperate using pipes, allowing a user to develop a relatively sophisticated query from a simple beginning.
GLBOX is a lightweight version of a sandbox. It monitors the execution of any program, regardless of the programing language in which it was written or the accessibility to source code. Since all processes access operating system resources via system calls, controlling those calls is the most general way to monitor a program's behavior.
Avast-ng gives you the ability to sift through vast amounts of log files and display current syslog data which is useful to you. It sifts out all the normal flotsam in your log files, and just displays messages which you have defined to be either out of the ordinary or unexpected. With its built in query builder, you can build new filters to include or exclude log messages quickly. It uses a nifty, intuitive AJAX interface. You can save multiple filters for quick access. Avast-ng continuously monitors your syslog messages, showing the most current messages matching your filter.
