For small networks, it’s easy to manage them. But as soon as the network starts growing, it becomes difficult to manage. To overcome this situation there are many free and paid network monitoring tools available in the market for network performance monitoring. Normally, we called them network monitoring tools.
There are many tools available in the market and they are growing every year. When it comes to network monitoring, it is not limited to software. There is a huge variety of devices that play a role in Network monitoring.
With today’s complex needs, some advanced network monitoring tools will also serve the purpose of network mapping and network management. But in this article, we will only discuss the effective monitoring of the network.
Selecting the best network monitoring software
When selecting Network monitoring tools, there are few things that we should consider:
- The device up and down alerting system
- The notification system like instant messaging, email, sms or other notification channels should be supported.
- The ability of its integration using SNMP and integration with old in place systems
- We might be interested in automation and fault resolution so that those tools can help saving our time.
- Network security monitoring can also be added to the monitoring tool for network traffic monitoring, analysis and alerting.
- It should work irrespective of the Operating System whether it is Windows, Linux, Mac or any mobile device. If the device is connected to the network, it should be supported and monitored.
There are different types of tools for monitoring different types of networks. For example, if you want to monitor services like IP addresses space usage, DNS and DHCP services, you will need IPAM software. And if you want to monitor Cisco specific equipment, you will need software which supports Netflow protocol. Other network devices may support SNMP protocol and can be monitored using the tools mentioned below.
