NetOculus is a network monitoring system that provides all the functions of the well-known monitoring system MRTG. It also has a number of its own benefits. It can automatically monitor any kind of detectable alteration in a computer network (and in relatively separated network areas). It can efficiently notify staff about hardware state changes. Analytical information is aggregated. Specific pieces of hardware are associated with the staff members who responsible for them. The solutions for solved problems are reported to the staff for further use.
pv (Pipe Viewer) is a terminal-based tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion.
IptablesWeb allows a user to inspect iptables logs and to receive email and alerts using a Web browser. It is plugin-based, portable to any database, and supports multiple languages and multiple users. It features the ability to duplicate each plugin in any number of blocks, each with its own characteristics. The update (refresh) time can be set on each block to reduce the CPU load. Blocks can be dragged and dropped to change their display order.
Pandora is a distributed system to monitor processes, performance, status, application, or operating parameters of almost any operating system. It has a decentralized management system, based on flexible user profiles, that allows the user to generate graphical reports, define alarms, and a full incident management system to operate a 24x7 monitoring team.
geo is a script that reads a file or input stream and looks for IP addresses in it. Then, it looks up the country that corresponds to the IP address and inserts the country name before the IP address. Optionally, it can suppress all output except for the IP address and/or country name.
MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). Merging of 2 or more log files is possible. It can also use colors while displaying the log files (through regular expressions) for faster recognition of what is important. It can also filter lines (again with regular expressions). It has interactive menus for editing given regular expressions and deleting and adding windows. One can also have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like 'watch'.
Unix Server Monitoring Scripts is a suite that will monitor Unix disk space, Web servers via HTTP, and the availability of SMTP servers via SMTP. It will save a history of these events to diagnose and pinpoint problems. It also sends a message via email if a Web server is down or if disk usage exceeds one of two thresholds. Each script acts independently of the others.
