Network Monitoring Tools

What is Network Monitoring?

The Network Monitoring Tools is common across the IT industry. Network monitoring is a critical IT process where all network components, such as routers, switches, firewalls, servers, and VMs, are monitored for error and performance, and are continually evaluated to maintain and optimize their usability. An important aspect of network monitoring is that it should be proactive. Finding performance problems and bottlenecks helps proactively identify problems at the first stage. Efficient proactive monitoring can prevent network downtime or malfunctions.

Important aspects of network monitoring:
  • Basic requirements monitoring
  • Optimizing the monitoring interval
  • Selecting the correct protocol
  • Adjusting the thresholds

Monitoring of Key Issues

Incorrect network devices affect network performance. This can be eliminated by early detection and therefore continuous monitoring of the network and associated devices is essential. The first step in active network monitoring is to determine the devices to be monitored and the relevant performance metrics. The second step is to determine the monitoring range. Devices such as desktops and printers are not critical and do not require frequent monitoring; however, servers, routers and switches perform critical tasks for business, but also have specific parameters that can be monitored selectively.

Monitoring range

The monitoring interval determines the frequency with which network devices and related measurements are interrogated to identify performance and availability. Adjusting the viewing intervals can help reduce the burden of the network monitoring system and then your resources. The range depends on the type of network device or parameter to be monitored. 

The availability of the devices, preferably the minimum time interval, must be monitored every minute. CPU and Memory statistics can be viewed every 5 minutes. For other measurements, such as disk usage, the monitoring range can be extended and interrogated every 15 minutes. The minimal monitoring of each device will only add an unnecessary burden to the network and is not necessary.

Protocol and its Types

When monitoring a network and devices, it is a safe and non-bandwidth network management protocol to minimize the impact on network performance. Most network devices and Linux servers support SNMP (Simple Network Management Protocol) and CLI protocols and Windows devices WMI protocol. SNMP is one of the widely accepted protocols for managing and monitoring network elements with Network Monitoring Tools. 

Most network items come with an SNMP agent. To communicate with the network management system (NMS), they only need to be enabled and configured. Allowing SNMP read-write access provides one control over the device. Using SNMP, the entire configuration of the device can be changed. A network monitoring system helps the administrator control the network by setting SNMP read / write privileges and restricting control for other users.

Proactive Monitoring and Thresholds.

The down time of the network can cost a lot of money. In most cases, the end user notifies the network management team of a network problem. The reason behind this is a weak approach to proactive network monitoring. The key challenge in real-time network monitoring is the proactive definition of performance bottlenecks. This is where network thresholds play an important role. Threshold limits vary from device to device depending on the operating state.

Immediate Warning Based on Threshold Violations

Configuring thresholds helps you to proactively monitor the resources and services that run on servers and network devices. Each device may have a range or threshold value set according to the user preference and need. The multi-level threshold can help to classify and mitigate any errors encountered. Warnings can also be increased by using thresholds before the device turns off or reaches a critical state.

Dashboards and Customization

The data is useful only when explicitly presented to the right audience. It is important for IT administrators and users to be informed about critical metrics at the time they log in. A network board, routers, switches, firewalls and servers, services, applications, URLs, printers, UPS and other Infrastructure devices. Widget support to track required features and real-time performance graphs can help administrators quickly troubleshoot problems and monitor devices remotely with Network Monitoring Tools.

High Availability and Fault.

What happens if your trusted network monitor solution is running on a server that is disconnected or lost? You'll want to be warned about this and you'll also want the status to be automatically corrected using a backup / backup of another twin-network monitor application installation. Each network event - device diseases, unhealthy bandwidth levels, DoS attacks, etc. Immediate notification should be made so that countermeasures can be taken immediately.

The failover and recoil function provides a network environment that is always monitored using a secondary standby server. If a failure occurs on the primary server, the secondary server is ready to inherit and the database is safe. This provides one hundred percent network and device uptime.

Benefits of Failover system:
  •  Instantly recognize the primary server failure.
  •  Immediate e-mail notification in case of primary server failure.
  • 100% uptime and continuous network management
  • Automatic and seamless switching between the primary server and the Standby Server.

Network Monitoring Solutions.

The network monitoring and management process is simplified and automated with network monitoring software and network monitoring tools. A network performance monitor is required to address network bottlenecks and performance issues that can adversely affect network performance issues.

Features of an effective network monitoring software:
  • Visualize your entire IT infrastructure by more classification than by type or logical group.
  • Automatic configuration of devices and interfaces with predefined templates.
  • Monitor network, server, and application performance and troubleshoot.
  • Implement advanced network performance monitoring techniques to quickly resolve network failures by getting to the source of the problem.
  • Obtain advanced reporting capabilities with provisioning to schedule reports and automatically post or publish with Network Monitoring Tools.
