Nagios is configured by building configuration files for each machine which is usually done to monitor small number of systems. The configuration of Nagios can also be automated by using shell scripting which is generally done in an industry, where the numbers of systems to be monitored are large. Both the above methods of configuration have been implemented in this project. The project has been successfully used to know the status of each service running on the defending team’s network. -

Fredrik Linder [email protected] Thesis for the Degree of Bachelor of Science in Engineering - Computer Network Engineering 15.0 hp IDT (academy for Innovation, Design and Technology) Mälardalen University Västerås, Sweden 2015-11-15 Supervisors: Peter Helin, ABB crane systems Stefan Löfgren, Mälardalen University Examinator: Mats Björkman, Mälardalen University | Network monitoring of automated harbor terminals | | Linder | ABSTRACT Nowadays, more information and services are migrated into computers using a network as the carrier for data communication. One example of this is the migration from PROFIBUS to PROFINET. The big problem is that there are no network monitoring solution implemented, despite the significance of the network. The drawback of not having a network monitor solution are many. This includes areas within security, availability, control and troubleshooting. The goal is to find a solution to this problem with providing a complete network monitor solution in ABB’s existing environment. The work was divided in four different parts, research, design, implementation and verification. Information from the World Wide Web (WWW) pointed towards that CentOS (operating system) together with OMD (network monitor software) would be the best choice for this task. The design phase described how all devices should be able to communicate with each other. The implementation part mostly were configuration of devices, such as servers, monitor software, switches and security. The configuration were made by using the built in user interface in each device. The verification part proved that all functions worked as expected, such as security and notifications. Rest of the verification could be seen in the web interface. The result is a complete solution demonstrated in ABB crane system’s lab, which includes a complete set of network devices that exist on sites all around the world. -

Deploying the BIG-IP LTM with the Nagios Open Source Network Monitoring System Archived Deploying F5 with Nagios Open Source Network Monitoring System Welcome to the F5 and Nagios deployment guide. This guide provides detailed procedures for configuring F5 devices with the Nagios Open Source Network Monitoring System. Network Management Systems (NMS) provide insight to device and application performance, system stability, network trouble spots and a host of other items that affect a company's ability to provide computer network services. Recent advances in automated event correlation, data storage and retrieval, as well as open source systems that allow greater integration, have greatly improved today's Network Management Systems. The Nagios system and network monitoring application is an open source project. Nagios maintains network status information by polling objects for specific service responses. Examples of monitored network services include SMTP, DNS, HTTP, and so on. For more information on the Nagios project, see http://www.nagios.org/ or http://sourceforge.net/projects/nagios/. For further Nagios resources and information, see http://community.nagios.org/. For more information on F5 devices described in this guide, see http://www.f5.com/products/big-ip/.

It has become impossible to carry out network management functions without the support of automated tools and applications. In this chapter, the major network management issues, including network management requirements, functions, techniques, security, some well- known network management protocols and tools, will be discussed. Location management for the wireless cellular networks will also be briefly described. Finally, policy-based network management, which is a promising direction for the next generation of network management, will be briefly described. Keywords: -

For this reason dependency on automated network monitoring has been increased. Objectives: There are many tools and systems available for network monitoring. This includes expensive commercial solutions to open source products. Nagios and OpenNMS are two of the most popular systems and they are considered to be close competitors. Comparison discussions about them are very common at different forums on internet. -
