Techniques for Network Monitoring
- NetFlow monitoring:- This technique traps the packet to examine the traffic that passes through a network. It captures the traffic data and then sends it to a monitoring tool for analysis. The analysis performed on these are examined as network traffic flow and volume to determine how data moves through the network. This flow-based processing system includes analyzing the communication or conversation between devices and ensuring that information and data is transmitted smoothly along the network path.
- Ping monitoring: This technique transmits or sends a packet to a device and waits for a response. If the device receives the response, then it is considered that the device is running or up and if there is no response, the monitoring tool sends multiple ping to get the device’s response and still there’s no response then the monitoring tool alter the user about the improper functioning of the device. This technique is considered as the oldest monitoring technique. Pings are a relatively simple monitoring technique, but it is still considered as the best way for industries to examine if the devices are currently running or not.
- SNMP monitoring:- Simple Network Management Protocol (SNMP) is a type of protocol that is used to monitor network devices. SNMP tool collects information from network devices and uses it to monitor network performances. It runs on a common language to communicate with each other. The system depends on the agents inside the device to provide the information to network monitoring tools. or network managers. An SNMP tool or manager send out polls to the device to inquire about their current status and the device can send the trap signal when any significant network events occur. NPMs that include the SNMP tool have a common framework to communicate with each other, centralizing and monitoring capabilities.
- SQL query Monitoring:- For monitoring the databases connected to the network, monitors can use SQL queries. The queries query the database to provide information on the number of requests, transmissions etc. Using the extracted information from the database is sending data across a network to accommodate for every request it receives or not. If it finds that the database is performing slowly the motoring tool can detect it and it will send an alert to admin department of network team.
Network Monitoring and Packet Capture Techniques
Computer networking is the interconnection of some devices which can communicate and exchange data among themselves. The communication can be either wired or wireless. In this article we will discuss how we can monitor and packet packets.
What is Network Monitoring and Packet Capture?
Network monitoring is the process of continuously monitoring a network for any reason like any system failure, slow traffic, some network-related problem, some data analytics etc. It is a very important process that helps to discover, map and monitor the network and the related devices and network components like switches, routers, servers, VMs (virtual machines) etc.
Packet Capturing:- Packet capture is the process of analyzing, intercepting, and recording data packets that are exchanged (transmitted or received) over a network. It is a important technique for analyzing performance issues, track packet loss, managing traffic etc. Packet capturing helps the admin department to detect vulnerabilities, intrusion detection attacks or attempts, undesirable network behaviors, network congestion etc.
