Monit is a utility for managing and monitoring processes, programs, files, directories, and devices on a Unix system. It conducts automatic maintenance and repair and can execute meaningful causal actions in error situations. It can be used to monitor files, directories, and devices for changes, such as timestamps changes, checksum changes, or size changes. It is controlled via an easy to configure control file based on a free-format, token-oriented syntax. It logs to syslog or to its own log file and notifies users about error conditions via customizable alert messages. It can perform various TCP/IP network checks, protocol checks, and can utilize SSL for such checks. It provides an HTTP(S) interface for access.
Performance Co-Pilot (PCP) is a framework and set of services for supporting system-level performance monitoring and performance management. It provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data using a single API. A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts. Archive logging and replay are integrated so that a client application can use the same API to process real-time data from a host or historical data from an archive.
AFD is a program to automatically distribute files either locally or to remote hosts. The files are distributed by using FTP or SMTP, and can be sent in parallel and with priority. It provides a GUI to monitor and control the distribution and extensive logging of all activities.
Cfengine is a tool for setting up and maintaining BSD and System-5-like operating system optionally attached to a TCP/IP network. You can think of cfengine as a very high level language, much higher level than Perl or shell: a single statement can result in many hundreds of operations being performed on multiple hosts. Cfengine is good at performing a lot of common system administration tasks, and allows you to build on its strengths with your own scripts.
Automated Password Generator is a set of tools for random password generation including a standalone password generator, an RFC972 password generation server, and a Perl client for the password generation server. These feature a built-in X9.17 random number generator, and 35 modes of password generation, including pronounceable password generation.
System Configuration Collector collects and classifies most of your Unix/Linux/BSD configuration data in flat files called snapshots. This allows changes in snapshots of consecutive runs to be detected. These changes are added to a logbook, which is helpful for administrators during troubleshooting and for auditors during audits. Snapshots and logbooks are also available in HTML format. All data can be send to an SCC server, where a Web interface provides access to summaries and supports comparing snapshots of different servers and searching of all data. A WMI-based Windows client is also available.
Directory administrator is a smart LDAP directory management tool. It can be used to manage UNIX and Samba user accounts and groups in a single sign-on setup, corporate address book information, host-based access control and advanced email routing. It's extremely easy to install and use, yet powerful at the same time.
