Monitoring network utilization is critical for efficiency, security, and peak performance in today’s data-driven environment. It enables managers to monitor bandwidth utilization, identify faults, and plan for capacity requirements. This prevents malicious activities and unauthorized data usage. This article discusses the tools, methodologies, and best practices for monitoring network utilization monthly.
Why Network Usage Monitoring is Important:
Optimization of Network Resources: Regular monitoring allows administrators to ensure that network resources are used efficiently. If certain users or applications are consuming excessive bandwidth, corrective actions can be taken to optimize usage.
Security: By analyzing traffic patterns and detecting unusual spikes or traffic types, you can identify potential security breaches, such as Distributed Denial-of-Service (DDoS) attacks or malware spreading across the network.
Cost Management: For organizations using bandwidth from an Internet Service Provider (ISP) that charges based on usage, monitoring network bandwidth ensures that you don’t exceed data caps or incur unnecessary costs.
Performance Issues: Constantly measuring network throughput helps to pinpoint bottlenecks or disruptions that affect overall network performance, such as slow connections or downtime.
Compliance: Many industries require regular reporting on network usage for compliance with regulations such as GDPR or HIPAA. Monitoring tools can generate reports to ensure that data privacy and security guidelines are met.
There are a variety of tools available to monitor network usage. However, we will be discussing NetCrunch Network Monitor tool and how we can use it to set up the monthly usage report.

How to Set Up Monthly Network Usage Monitoring Using NetCrunch Monitoring Tool
Setting up monthly network usage monitoring in NetCrunch is a multi-step process. NetCrunch is a powerful network monitoring solution that helps you keep track of network health, performance, and traffic usage. You need to configure appropriate data collection, reporting, and alerting to monitor network usage on a monthly basis, .
Here’s a step-by-step guide to set up monthly network usage monitoring in NetCrunch:
1)Install NetCrunch: First, ensure that NetCrunch is installed and configured properly on your network. Download the NetCrunch software from the official website and install it on a machine that will act as the monitoring server.
2)Add Devices to NetCrunch: Open NetCrunch and log in to the web or desktop console. Add the network devices (routers, switches, servers, etc.) that you want to monitor. Go to Admin > Devices. Click on Add Devices and input the necessary details (IP address, device type, SNMP credentials, etc.).
3)Enable Traffic Monitoring: To monitor network usage, you need to ensure that traffic data collection is enabled. Do the following steps:
a) For devices like routers or switches, ensure that SNMP (Simple Network Management Protocol) is enabled on those devices.
b) In NetCrunch, configure SNMP monitoring for the devices:
c) Navigate to the Devices section and select the device you want to monitor.
d) Under Monitoring options, select SNMP or other relevant protocols (such as NetFlow or sFlow).
e) Once SNMP is set up, NetCrunch will start collecting data about the network interfaces, including traffic (in/out), bandwidth utilization, and errors.
4)Configure Data Collection Period: NetCrunch allows you to set how often the data should be collected. For monthly tracking, you will likely need to collect data at least every day or hour, then generate monthly reports. Do the following steps:
a) Go to Settings > Polling Settings.
b) Set the polling frequency for the relevant devices (e.g., polling every 5 minutes, 15 minutes, or 1 hour).
5)Create Monthly Reports: Create a custom report to monitor network usage over the course of a month. NetCrunch has built-in report templates, but you can create your own to match your specific needs. To create a monthly network usage report, do these steps:
a) Go to the Reports section.
b) Click on Create Report or use a predefined Traffic or Bandwidth Usage report.
c) Customize the report by selecting the time range you want (e.g., monthly). You can also set it to automatically generate reports each month.
d) Choose the devices and interfaces you want to monitor and ensure that you’re tracking both incoming and outgoing traffic (e.g., bandwidth usage, packet count, etc.).
6)Configure Data Retention: Make sure that data is being retained long enough to perform monthly analysis:
a) Go to Admin > Data Retention.
b) Set the retention period to store historical network usage data for a sufficient period of time (e.g., 30 days or more) so that monthly reports reflect accurate usage.
7) Set Up Alerts for High Usage: It’s also a good idea to configure alerts to notify you of unusually high usage, which could indicate a problem (e.g., network congestion, potential security issue). To set alerts, do the following steps:
a) Navigate to Admin > Alerts.
b) Configure Threshold Alerts to monitor bandwidth usage for each device.
c) For monthly monitoring, set the threshold to alert you if any device exceeds a predefined usage threshold, such as 90% of its available bandwidth.
d) Set up notification preferences (email, SMS, etc.) to be notified when alerts are triggered.
8) Schedule Monthly Reporting:
a) Once you’ve created your custom reports, you can schedule them to be sent to you automatically.
b) In the Reports section, click on the report you want to schedule, and then select the option to Schedule.
c) Set the report to be sent monthly (or at your desired frequency) and configure the email recipients.
9)View and Analyze Monthly Network Usage: After a month of data collection, you can view network usage reports directly from the Reports section. These will include summaries of data usage, trends, and potential issues. Do these steps:
a) Go to the Reports tab.
b) Open the Monthly Bandwidth Usage report (or any custom report you’ve created).
c) Review the data in terms of total traffic, usage by device, and interface bandwidth utilization.
10)Export Reports (Optional): If you need to export the monthly network usage data, you can do so from the Reports tab by selecting the report you want and choosing the Export option (e.g., to CSV, PDF, or Excel).
11)Review Performance Over Time: NetCrunch’s visualizations and historical data will allow you to analyze trends over time, including monthly usage patterns. You can use the dashboard and graphs to see network performance and identify any
By following these steps, you can set up monthly network usage monitoring in NetCrunch, helping you track the health and performance of your network on an ongoing basis. You’ll also be able to take corrective actions based on usage trends, potential bottlenecks, or issues with certain devices.
Best Practices for Effective Network Usage monitoring
Regularly Update Software: Always ensure that your monitoring tools are up to date to take advantage of new features and security patches.
Be Proactive, Not Reactive: Regular monitoring helps you stay ahead of issues before they escalate into major problems.
Backup Your Data: Ensure that your monitoring data is backed up, especially if you’re tracking historical usage trends for compliance or audit purposes.
Monitor in Real-Time: While monthly reports are important, real-time monitoring allows you to catch issues as they happen.
Secure Access to Monitoring Tools: Securing access to network monitoring tools is critical to prevent unauthorized users from altering configurations, gaining sensitive information, or disrupting network operations. By employing a combination of strong authentication, encryption, access control, auditing, and secure infrastructure practices, you can significantly reduce the risk of security breaches. This will also ensure that only authorized users have access to your monitoring system. Implementing these strategies will help protect your network’s integrity and keep it resilient against both external and internal threats.
Conclusion
Monitoring network usage on a monthly basis is vital for maintaining network efficiency, security, and performance. By using the right tools, configuring alerts, and analyzing trends, you can optimize your network, reduce costs, and ensure compliance with regulations.
