Troubleshooting procedures will involve knowledge databases, guides, and processes to cover the role of network operations engineers from initial diagnostics to advanced troubleshooting. This stage often involves problem simulation and is the traditional interface to design.
Example of a basic network diagram. Network documentation is a form of technical documentation, the goal of which is to maintain computer networks. [1] It contains information about how the network is built, how it should perform, and where to troubleshoot problems.
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
Monitoring: This function enables the network management software to monitor the network for problems and to suggest improvements. [2] [3] The software may poll the devices periodically or register itself to receive alerts from network devices. One mechanism for network devices to volunteer information about itself is by sending an SNMP Trap ...
Troubleshoot performance problems by monitoring network data from an application Serve as the primary data source for day-to-day network monitoring and management Spy on other network users and collect sensitive information such as login details or users cookies (depending on any content encryption methods that may be in use)
Software-defined networking (SDN) is an approach to network management that uses abstraction to enable dynamic and programmatically efficient network configuration to create grouping and segmentation while improving network performance and monitoring in a manner more akin to cloud computing than to traditional network management. [1]
The OpenDataPlane project is an open-source, cross-platform set of application programming interfaces (APIs) for the networking data plane. ODP consists of an API specification and a set of reference implementations that realize these APIs on different platforms. [3]
dig is a network administration command-line tool for querying the Domain Name System (DNS).. dig is useful for network troubleshooting and for educational purposes. [2] It can operate based on command line option and flag arguments, or in batch mode by reading requests from an operating system file.
