[51CTO.com Comprehensive Report] Wherever there is a network, network management is a necessity. Today鈥檚 computer networks are characterized by ever-expanding scale and increasing complexity. How to more effectively leverage enterprise IT resources to achieve stable network support and maximize network benefits has always been a challenging issue for network administrators.
Enterprises invest heavily in purchasing network equipment and building WANs, LANs, and Internet access networks. However, the variety and types of network devices are vast, including routers, switches, load balancers, and firewalls. How to manage them more effectively is the primary issue that must be addressed.
How to Determine Current Network Usage
Network administrators typically can only view and analyze the usage status of network devices through SNMP or device log files, including basic device information, CPU, Memory, board information, as well as port traffic data, packet loss rates, and error packet rates.
Log files can meticulously record the various events that occur in the system daily, playing a crucial role in network security. With a large number of devices on the network, checking each one individually is extremely time-consuming and labor-intensive. An effective log data collection method should be established in daily network management to aggregate all log records, facilitating management and querying, and extracting useful log information for network management purposes. This allows for the timely discovery of issues during device operation, thereby better ensuring the stable operation of the network.
Some fault log information from network devices, such as environmental alerts and SNMP access failures, is reported via SNMP Traps. By interpreting the Trap field values in SNMP data packets, you can obtain critical information about a network device, completing the information monitoring and data collection for network devices.
Creating More Effective Management Our Way
Unify the display of different content through a portal, receive SNMP Traps and SYSLOG sent by network devices, analyze them, and ultimately feed them into event management to generate fault alarms. As shown below:
