Network Monitoring

Network Monitoring

In today's world, the term network monitoring is widespread throughout the IT industry. Network monitoring is a critical IT process where all networking components like routers, switches, firewalls, servers, and VMs are monitored for fault and performance and evaluated continuously to maintain and optimize their availability. One important aspect of network monitoring is that it should be proactive. Finding performance issues and bottlenecks proactively helps in identifying issues at the initial stage. Efficient, proactive monitoring can prevent network downtime or failures.

Faulty network devices impact network performance. This can be eliminated through early detection, and this is why a continuous monitoring of the network and related devices is essential. Ineffective network monitoring, at first, is to identify the devices and the related performance metrics to be monitored. The second is determining the monitoring interval. Devices like desktops and printers are not critical and do not require frequent monitoring whereas servers, routers and switches perform business-critical tasks but at the same time have specific parameters that can be selectively monitored. Monitoring interval determines the frequency at which the network devices and their related metrics are polled to identify the performance and availability status. Setting up monitoring intervals can help to take the load off the network monitoring system and in turn, your resources. The interval depends on the type of network device or parameter being monitored. The availability status of devices has to bemonitored at the least interval of time preferably every minute. CPU and memory stats can be monitored once every 5 minutes. The monitoring interval for other metrics like Disk utilization can be extended and is sufficient if it is polled once every 15 minutes. Monitoring every device at the least interval will only add unnecessary load to the network and is not quite necessary.

When monitoring a network and its devices, a common good practice is to adopt a secure and non-bandwidth consuming network management protocol to minimize the impact it has on network performance. 

Network downtime can cost a lot of money. In most cases, the end-user reports a network issue to the network management team. The reason behind this is a poor approach to proactive network monitoring. The key challenge in real-time network monitoring is to identify performance bottlenecks proactively. This is where thresholds play a major role in network monitoring. Threshold limits vary from device to device based on the business use case.

Failover and fail-back functionality ensure an always-monitored network environment by utilizing a secondary standby server. If a failure occurs in the primary server, the secondary server is readily available to take over, and the database is secure. This ensures a hundred percent network and device uptime.

The process of network monitoring and management is simplified and automated with the help of network monitoring software and network monitor tools. A network monitor system is essential to tackle network bottlenecks and performance woes that might harm network performance. With the sudden spurt in enterprise network monitoring and remote network monitoring, a wide range of network monitoring device and network monitoring solutions are available in the market. An effective network management system will contain a built-in network monitor tool that can help admins cut down on the workforce and automate basic troubleshooting techniques.
