Trafficmeter is a traffic collecting and logging system. It collects and groups packets by time, source IP, destination IP, protocol, source port, and destination port. You can get a detailed log of traffic for every IP without any daemon configuration work. It also gives statistics of IP incoming and outgoing traffic for a time period.
DBLog is a logging program for radio amateurs based on a relational database. It allows the user to log QSOs and export a range of them in ADIF format. It can read the radio frequency via CAT interface. It includes a CW Keyer based on cwdaemon. It works with fldigi for digi-modes, and can store QSL pictures with QSO data.
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.
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.
Alerttail monitors a given file and executes a list of actions when a user-defined text pattern has been written to the file. For example, the user can pop up a GTK notification window when a certain message is written to a log file. Actions can be alerttail built in actions (GTK notify action, geoipLocalization action, or filtering text action) or a custom user defined shell command action. A Qt 4 GUI frontend helps with configuration.
