Different types of technology for monitoring your network

There are many kinds of technology for monitoring your network. The most common ones are SNMP, sFlow, NetFlow, and JFlow.

SNMP stands for Simple Network Management Protocol. It is a set of standards that allow you to monitor your network components and devices SNMP remotely. SNMP is the most popular protocol for monitoring networks because it is free and open-source.

sFlow is a protocol for network traffic analysis used to measure the amount of data flowing through a network. There are plenty of use cases for sFlow, such as monitoring bandwidth utilization, identifying network bottlenecks, and identifying which applications use the most bandwidth on a network.

Netflow is a protocol that is used to measure internet traffic. It was created by Cisco Systems in 1996. Netflow can be used for many purposes, such as detecting network congestion and malicious activity. Netflow data can be exported to other software packages for more detailed analysis.

J-Flow is Juniper’s proprietary protocol for collecting and monitoring IP flows. It can be used to sample data on Juniper routers, like how Cisco Netflow works.

How to set up a network monitoring system?

There are many different types of network monitoring systems available on the market today. They vary in complexity and price. The most basic ones are usually free or have a low cost and provide only basic functions such as email alerts for device failures or bandwidth usage alerts. More advanced systems like Motadata offer more features such as graphing, reporting, and alerting on specific events like port scans or failed logins.

A network monitoring system can be set up by following these steps:

– Identify the network components and their respective roles.
– Identify what kind of data you want to monitor, e.g., bandwidth, latency, packet loss, etc.
– Choose a software or hardware solution for your needs.
– Configure the chosen solution according to your needs and requirements.

Network monitoring common practices

There are many different things to monitor, but the most common ones are:

Server Storage monitoring: Disk issues can become a serious problem for business continuity. Disk monitoring can identify I/O operations of logical disks and can help teams establish threshold limits to receive warnings when network metrics reach a critical level set by department or organization.

Availability monitoring: To guarantee organizational functionality, IT infrastructure needs to be available around the clock to meet the needs of contemporary businesses. For that reason, availability monitoring—the process of examining all the networking features and resources within an enterprise to ensure continuous operation—is vital.

Network hardware monitoring: The networking hardware supplies the structure for a whole IT infrastructure. Any issue with the internal network hardware will cause massive network issues. Therefore, it is essential for network hardware monitoring to ensure the stability of the whole network.
