NetXMS is a network monitoring and management system with a modular architecture. It can be used for monitoring an entire IT infrastructure, starting with SNMP-capable hardware (like switches and routers) and ending with applications on servers. The system has a three-tier architecture; the information is collected by monitoring agents (either its own agents or SNMP agents) and delivered to the monitoring server for processing and storing, where it can be accessed by using the management console. It features centralized configuration and centralized agent upgrades.
Nagstamon is a Nagios status monitor with a UI that resides in the systray or as a floating statusbar on your desktop. It informs you in realtime about the status of your Nagios, Icinga, Opsview, Ninja, Check_MK/Multisite, Centreon, or Thruk-monitored network. It alerts you with sound and visual notification. Failed hosts and services are easy to connect with by SSH, RDP, and VNC. Custom actions can be run on certain events. It works best with GNOME, but also with KDE, Mac OS X, and Windows.
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.
Zenoss is an enterprise network/systems management application that provides an integrated software package for monitoring availability, performance, events, and configuration across layers (network, servers, applications, environment, etc.) and across platforms (Linux, Windows, Unix, etc.).
PowerBroker Identity Services is an application that joins Linux, Unix, and Mac OS machines to Microsoft Active Directory and securely authenticates users with their domain credentials. Features include: joining non-Windows systems to Active Directory domains in a single step from the command line or from a GUI; authenticating users with a single user name and password; enforcing the same password policies for all platforms; supporting multiple forests with one-way and two-way cross forest trusts; caching credentials in case your domain controller goes down; and providing single sign-on for SSH and Putty. It does not require Active Directory schema changes for installation.
openpom is a Web interface based on NDO for Nagios or Icinga. It allows you to view almost everything about Nagios or Icinga in a single page: alert, ack, downtime, comment. You can also interact with Nagios or Icinga through ack, downtime, comment, disable, and reset buttons. You can filter on hosts and services states (such as critical, warning, unknown, ok, or outage). The status popin allows you to display graphs, either the ones from Nagios (trends.cgi) or custom ones based on RRD (such as pnp4nagios).
dim_STAT is a performance analysis and monitoring tool for Solaris, Linux, Mac OS X, and other UNIX systems. Its main features are a Web-based interface, data storage in a MySQL database, several data views, interactive (Java) or static (PNG) graphs, real-time monitoring, multi-host monitoring, post analyzing, statistics integration, professional reporting with automated features, and more.
httpry is a specialized packet sniffer designed for displaying and logging HTTP traffic. It is not intended to perform analysis itself, but instead to capture, parse, and log the traffic for later analysis. It can be run in real-time displaying the live traffic on the wire, or as a daemon process that logs to an output file. It is written to be as lightweight and flexible as possible, so that it can be easily adaptable to different applications. It does not display the raw HTTP data transferred, but instead focuses on parsing and displaying the request/response line along with associated header fields.
RHQ is a management platform for everything from the OS level load and network metrics through common databases to application servers and projects. The system includes support for monitoring and/or managing Apache httpd, Apache Tomcat, JBoss Application Server, PostgreSQL, and other popular open source projects. It is built on the powerful RHQ plugin model that allows for the quick development of support for new projects. It supports inventory auto-discovery, rich monitoring and alerting, operational control, configuration management, content deployment, log tracking, and full history and auditing. It supports fine-grained security and rich group management.
