ZABBIX is an enterprise-class distributed monitoring solution designed to monitor and track performance and availability of network servers, devices, and other IT resources. It supports distributed and Web-based monitoring, auto-discovery, real-time monitoring, SLA assurance, trending, and more.
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'.
Spinlogs is a shell script for rotating system logs. It is configurable through a text file similar in format and featureset to the newsyslog program in FreeBSD. Any Unix system running ksh should be able to use it. There are many options defining how and when log files should be rotated, and the config file is very straightforward. Rotating log files is a pretty simple task, but some commercial platforms don't include anything better than the old "newsyslog", so this is provided as a system-independent alternative.
svclean is a set of utilities for enhancing svscan and supervise. With these tools, you get clean shutdown (i.e. services are guaranteed to be stopped before their loggers, so no logs are lost) and supervised logging of svscan's and supervise's output (so if the last-resort logger is killed, it can be restarted). These features are practically necessary for running svscan as process 1, but are useful even when svscan does not run as process 1.
The DAP daemon runs entirely as a non-privileged user and sends regular updates of the server status to a specified set of peers in a cluster. You can specify any number of information elements, such as uptime, networkdevice counters (packet/octet), logged in users (via utmp), load averages, and memory/swap usage.
Complete System Resource Monitor and Task Organizor consists of a daemon, a client, and a WWW-server (within the daemon). The daemon can run tasks and handle client-daemon and WWW-daemon requests. Clients can receive statistics and issue commands. Monitoring and maintenance is performed as prescheduled tasks. The system includes a process monitor and handler, a basic WWW-client, and a console client.
