Network Management
Introduction
Network Management is a crucial part of maintaining the health, performance, and security of an IT infrastructure. This document outlines the features and capabilities of a comprehensive network management system designed for proactive monitoring, resource management, and troubleshooting.
Key features include the ability to scan subnet ranges, add SNMP devices, manage network links, monitor bandwidth utilization, and track server performance (specifically RAMS utilization). Additionally, the system offers robust alerting and notification capabilities, ensuring the team is promptly informed of critical events such as device status changes or over-utilization of network resources.
Key Features
1. Scan Subnet Range
The Scan Subnet Range feature allows administrators to scan and detect devices across a specific IP range or subnet within the network. This feature provides a quick overview of network devices by identifying all active hosts within a given range, including their IP addresses, device names, and network status.
- Dynamic Scanning: Can automatically detect new devices as they are added to the network.
- Batch Scanning: Allows administrators to scan multiple subnets or IP ranges simultaneously.
- Device Classification: Devices can be classified by type (e.g., routers, switches, servers) for easier management.
2. Add SNMP Device
Adding SNMP-enabled devices to the network management system is simple and efficient. The system supports SNMPv1, SNMPv2, and SNMPv3 protocols, ensuring compatibility with a wide range of network hardware.
- Auto-Discovery: The system can automatically discover SNMP devices when scanning the subnet range.
- Custom SNMP Polling: Define custom polling intervals and thresholds for performance metrics (e.g., CPU load, memory usage, temperature).
- Link Monitoring: Continuous monitoring of device links for status changes such as Link Up/Down events.
- Alerts and Notifications: Immediate alerts via email when a link goes down or when a monitored metric exceeds the threshold.
3. Link Management
The Link Management feature allows administrators to monitor and manage all network links between devices. This includes tracking the operational status of links, their throughput, and ensuring that network traffic flows efficiently between devices.
- Link Status Monitoring: Real-time monitoring of link statuses (up/down) and operational health.
- Link Capacity Analysis: Track link utilization and detect potential bottlenecks.
- Alerting: Email notifications for any link status changes (e.g., a link goes down) or when performance issues (like bandwidth overload) are detected.
4. Link Dashboard
The Link Dashboard provides a graphical overview of all network links in the system. It presents information on the status and health of each link, allowing administrators to quickly detect issues and analyze network performance.
- Visual Layout: Links are displayed on an easy-to-navigate interface, categorized by device, status, and link type.
- Real-time Statistics: Live metrics on link health, throughput, and utilization.
- Historical Trends: View historical link performance to identify patterns or recurring issues.
5. Bandwidth Management
Bandwidth management allows administrators to control and optimize the bandwidth allocation for different network segments. This feature helps in preventing network congestion, ensuring that critical applications receive sufficient bandwidth while minimizing the impact on non-essential services.
- Bandwidth Allocation: Set limits on bandwidth usage for different devices or subnets.
- Traffic Shaping: Apply rules to control the flow of traffic and prioritize critical applications.
- Utilization Alerts: Email notifications are triggered when a bandwidth threshold is exceeded.
6. Bandwidth Dashboard
The Bandwidth Dashboard gives administrators a clear view of overall network bandwidth consumption. It aggregates data from all devices to present real-time and historical bandwidth usage statistics.
- Real-time Monitoring: Track bandwidth usage on a per-device or per-link basis.
- Usage History: View historical bandwidth usage and identify trends or spikes in network traffic.
- Threshold-based Alerts: Get notified via email when bandwidth utilization reaches configured thresholds.
7. RAMS Server Utilization
RAMS (Remote Access Management Server) is an essential part of the network infrastructure, often responsible for handling large amounts of data and user requests. The RAMS Server Utilization feature tracks and monitors the performance of the RAMS server, focusing on key metrics like CPU usage, RAM consumption, and disk I/O.
- CPU Monitoring: Track CPU utilization in real-time to ensure that processing power is not being overwhelmed.
- Memory Utilization: Monitor RAM usage and set alerts for high memory consumption, which could indicate a need for scaling or optimization.
- Disk I/O: Track disk read/write operations to prevent potential bottlenecks.
8. RAMS Server Dashboard
The RAMS Server Dashboard provides a unified view of the RAMS server’s performance. This dashboard aggregates critical metrics from the server to help administrators make data-driven decisions for server scaling or optimization.
- Comprehensive Metrics: Displays real-time CPU, RAM, and disk utilization metrics.
- Alerts and Thresholds: Set thresholds for high server utilization and receive instant email notifications when the server exceeds defined limits.
- Historical Trends: Review historical server utilization data to understand long-term performance patterns.
9. Link Up/Down Monitoring and Alerts
The network management system continuously monitors the operational status of network links. If a link goes down, the system will automatically trigger an alert via email to notify administrators.
- Real-time Monitoring: All link status changes (up/down) are tracked in real time.
- Instant Alerts: Admins receive immediate alerts via email to address connectivity issues promptly.
- Link Recovery Notification: Email alerts are sent when a link is restored to service.
10. Server Over-Utilization Monitoring and Alerts
Over-utilization of server resources, particularly CPU, RAM, and disk, can lead to performance degradation or downtime. The system offers comprehensive server over-utilization monitoring and sends alerts via email when resource consumption exceeds predefined thresholds.
- CPU Alerts: Get notified when the CPU usage exceeds a set threshold.
- Memory Alerts: Receive alerts when RAM usage goes beyond a critical level.
- Disk Usage Alerts: Monitor disk space utilization and set alerts for low disk space or high read/write operations.
11. User Interface and Reporting
The system's user interface (UI) is designed to provide administrators with quick access to all network resources and performance data. The UI features:
- Graphical Dashboards for network links, bandwidth, and server utilization.
- Interactive Charts to analyse historical performance data.
- Real-time Alerts Panel for viewing active alerts and events.
- Custom Reports that can be generated for audits, performance reviews, or troubleshooting.
12. Custom Alerts and Email Notifications
The system allows administrators to configure custom alerts for various network parameters such as:
- Link Status (Up/Down)
- Bandwidth Utilization
- RAMS Server Utilization
- Over-utilization of server resource
Alerts can be configured to send notifications to one or more email addresses, ensuring that network administrators are promptly notified of any critical events.
Overview
This Network Management System is designed to provide organizations with the tools needed to effectively monitor and manage their network infrastructure. By incorporating features like subnet scanning, SNMP device management, link and bandwidth monitoring, server utilization tracking, and robust alerting mechanisms, it ensures optimal network performance, fast issue detection, and quick resolution. With the inclusion of real-time dashboards and email notifications, the system offers a powerful, proactive solution for maintaining a healthy and efficient network.
