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'.
Big Brother is a combination of monitoring methods. Unlike SNMP where information is just collected and devices polled, Big Brother is designed in such a way that each local system broadcasts its own information to a central location. Simultaneously, Big Brother also polls all networked systems from a central location. This creates a highly efficient and redundant method for proactive network monitoring.
Bandwidth Monitor NG is a small console-based live network and disk I/O bandwidth monitor for Linux, BSD, Solaris, Mac OS X, and others. It supports /proc/net/dev, netstat, getifaddr, sysctl, kstat, /proc/diskstats, /proc/partitions, IOKit, devstat, and libstatgrab. An unlimited number of interfaces and disks are supported. Interfaces and disks are added or removed dynamically from the list. You can white or blacklist interfaces and disks. The output includes KB/s, Kb/s, packets, errors, average, max, and total sum, and can be viewed via curses, a plain console, CSV, or HTML. Configuration can be done through a config file or the command line.
Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
bcnu is a Web-based system management tool which delivers information on the status of networked systems in a simple and easy-to-use manner. It uses a web browser to display information about hosts in a tabular form. Historical information can be held indefinitely, and there is a powerful query tool available to interrogate it. Client systems can run an agent which logs information back to a central system. An agent scheduler is integrated to allow agents to be run at different intervals. Standard agents include ftp, http, disk space, logfiles, processes, and more.
Nets is a flexible and extensible network inventory and asset management system that works on all Unix and Windows platforms, and works with most SQL databases. Its complete GUI allows you to maintain details of your entire network, from network links down to interfaces and routers. It assists in provisioning, costing, reporting, and maintaining network details. It includes a network browser, an extension API, and plugins for IP address map visualisation, reports, schematics.
NEPM monitors and reports uptime, critical events and their predecessors, access rates, bytes-served rates, and error rates for network node equipment. Hardware and software elements within the nodes are tracked and reported separately to make possible rapid fault isolation. It is a very general, highly configurable, two-part software system that captures and analyzes logged performance data from IP-networked equipment and reports it via email and Web pages. Current conditions and history from systems based on Windows NT/2000, Unix, and Unix-style operating systems can be tracked and reported. Most major server, switch and router systems can be monitored, without running agents on the target systems. NEPM itself is system-independent and can be hosted on either a Unix or Win NT system or a combination of these with equal ease.
