check_openmanage is a plugin for Nagios that checks the hardware health of Dell servers running OpenManage Server Administrator (OMSA). The plugin can be used remotely with SNMP or locally with NRPE, check_by_ssh, or similar. It checks the health of the storage subsystem, power supplies, memory modules, temperature probes, etc., and gives an alert if any of the components are faulty or operate outside normal parameters.
check_logfiles is a plugin for Nagios which checks logfiles for defined patterns. It is capable of detecting logfile rotation. If you tell it how the rotated archives look, it will also examine these files. Unlike check_logfiles, traditional logfile plugins were not aware of the gap which could occur, so under some circumstances they ignored what had happened between their checks. A configuration file is used to specify where to search, what to search, and what to do if a matching line is found.
check_oracle_health is a plugin for the Shinken (Nagios) monitoring software that allows you to monitor various metrics of an Oracle database. It includes connection time, SGA data buffer hit ratio, SGA library cache hit ratio, SGA dictionary cache hit ratio, SGA shared pool free, PGA in memory sort ratio, tablespace usage, tablespace fragmentation, tablespace I/O balance, invalid objects, and many more.
Passwd_exp notifies users via email of upcoming password or account expiration. Its simple modular architecture allows you to perform expiration checks on any data source you use (SQL databases, LDAP...), send expiration warnings only to desired users or group and on selected days only. Administrators can use it to review expired accounts in the system. Support for Linux and Solaris shadow (including LDAP and NIS systems) and BSD passwd systems is included.
Tellu is inventory management software that collects hardware and software information automatically from networked servers and workstations, and stores collected data in MySQL database where data is easily readable using a comprehensive user interface usable by any modern Web browser. Devices (like routers and switches), peripherals (like video projectors and displays), and service providers (like hosting and maintenance) can also be stored in the database using a Web interface called Tellu Skin. Inventory management is only one part of Tellu's capability, Tellu offers the possibility to group together workstations, servers, devices, passwords, file attachments, and others to form a faction. For example, a faction can contain all the stuff that a development team needs in their development environment.
Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable. A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.
GResolver is a graphical DNS query tool. It allows system administrators to quickly and easily make the most common DNS queries without constructing lengthy dig commands. It supports all the main resource record types, including AAAA, AXFR, MX, and TXT, and the appropriate in-addr.arpa address is constructed from dotted-quad IP addresses when doing PTR queries. There are checkboxes for controlling the most commonly used options.
Aranha is an application that uses an XML-RPC layer to retrieve information from one or more servers. The type of information gathered is implemented via plugins, and can be displayed or archived in several different ways. The data is gathered in Round Robin Databases (integrated with rrdtool) and can be accessed using a XUL interface available from the system. Plugins are very easy to write.
