Automatic host discovery

Generally a system administrator who wants to integrate its hardware and software infrastructure into the Nagios configuration for monitoring, is required to add each single host into the configuration.

Although there are many possibilities to accelerate this task, like the web based configuration architect Monarch of NetEye, or the possibility to define templates for hosts and services to auto complete default settings, the time needed remains rather high.

Beside the time to spend to integrate the infrastructure host by host, there arises also the risk to oversee a host that should be included into the monitoring and possible failures are then not discovered in time.

For this has been integrated a new feature into NetEye coming with the purpose of a quick integration of your server and service infrastructure into the monitoring environment.

The monitoring discovery module allows to define a segment of your network to scan for available hosts that can be discovered and included into the monitoring. The scanning is done by making use of standard network tools like Nmap,  Ping, TCP and SNMP. With the help of those tools it is already possible to discover a certain number of installed services discoverable via web.

Once defined an address rage to scan trough, the scan process can be started by selecting the desired Range/Filter profile. After a click on “GO” and the confirmation for having temporarily disarmed any eventually installed IDS (intrusion detection system) the scan process is started.

Finally the result is listed with an overview of all discovered hosts. At this moment it is possible to adapt and personalize the settings of the single hosts, bye setting also the desired templates and group.

Once confirmed the configuration is included directly into the configuration and is ready to be committed into the running configuration of the Nagios monitoring agent.

Product Manager at Würth Phoenix
After my graduation in Applied Computer Science at the Free University of Bolzano I decided to start my professional career outside the province. With a bit of good timing and good luck I went into the booming IT-Dept. of Geox in the shoe district of Montebelluna, where I realized how a big IT infrastructure has to grow and adapt to quickly changing requirements. During this experience I had also the nice possibility to travel the world, while setting up the various production and retail areas of this company. Arrived at Würth Phoenix I started developing on our monitoring solution NetEye. Today, in my position as Product Manager, I aim to continuously improve our solutions and to adapt them to actual market requirements.
