For industrial switch device，such as Industrial Switch 8 port，in addition to the software function, there are also many independent industrial switch tools for operation, which support link detection, traffic check, message grab and connected diagnosis, which can complete the network problem analysis, quickly locate the on-site fault, simplify the operation of the industrial field.
I. Industrial Switch Tools:network monitoring tool
What is monitoring?
ü Link quality: delay, bag and jitter
ü Device status: cpas, memory, online status
ü Interface traffic: bandwidth utilization, emergency flow
ü Alarm event: interface downlimit, threshold and service exception
Common tools are:
Zabbix
Zabbix is an enterprise distributed open source monitoring solution based on the web interface, which can monitor server cpas, memory, disk and network performance data guarantee system safe operation, and also show the visualization diagram & the analysis function, also supporting real-time monitoring of tens of thousands of servers, virtual machines and network equipment to collect millions of monitoring indicators.
Prometheus + Grafana
The dashboard relies on this mainstream open source monitoring scheme, which implements full dimensional monitoring of programs, systems and business services. Complete index collection, persistence storage and multidimensional retrieval, support alarm trigger, visual dashboard display and various kinds of operation and analysis scenes.
Grafana
It is a cross-platform open source data visualization and analysis tool, which is mainly used for monitoring and presentation of large-scale index data, not directly responsible for data storage, but by interface from the underlying database to carry out rendering.
PRTG
Prtg(Paessler Router Traffic Grapher) is a network monitoring software. It monitors the bandwidth usage, flow load and performance status of servers, routers, switches and other devices in the network through SNMP、NetFlow、data packet sniffing. The software can generate graphical reports and dashboards, which can be used for network management and performance optimization. PRTG provides custom alerts and remote access capabilities that support centralized management of IT infrastructure. It is easy to use and suitable for small and medium-sized network monitoring.
LibreNMS
A powerful network monitoring system based on the SNMP protocol, which automatically finds devices such as switches and routers in the network, and monitors key data such as CPU, memory, bandwidth in real time. Through the visual diagram, the operator can easily master the operation of the network equipment and greatly improve the efficiency of the work.
Nagios
An open source free network monitoring tool that can effectively monitor Windows , Linux and Unixs host status, switch router and other network devices, printers, etc. When the system or service status is abnormal, it will send out email or text alarm to the network operation people. In summary, monitoring is not just about looking at the charts; it is about keeping you constantly informed about: where things are normal and where they are deteriorating.
2. scanning and discovery tools
What problems can we solve?
ü What are the online hosts in the network
ü What ports are open to the outside world
ü What services are running
ü Is the asset boundary clear
Common tools are:
Masscan
An high speed port scanning tool, which claims to be able to scan the entire Internet in a few minutes, is suitable for rapid discovery of large-scale online assets. First, using masscan to discover the open port, and then using Nmap to conduct detailed service identification and vulnerability detection on the discovered ports, by this way is the most efficient.
Nmap
The core functions of the Nmap（Network Mapper）include host discovery, port scan, service version identification and operating system fingerprint detection, and the implementation of hidden scans through TCP SYN、UDP detection, support firewall avoidance strategies such as segmentation and IP camouflage. The built-in NSE script engine extends vulnerability detection and advanced analysis capabilities, providing command lines and Zenmap graphical interfaces, which are widely used in network asset management, security assessment, and so on.
arp-scan
A tool designed to quickly scan the active devices in the LAN, it can help you find out what devices are online in the current network, and show their IP address and the MAC addresses and the information of the factory. The core value of this tool is "fast" and "accurate, especially suitable for network administrators or users who need to check the Internet problem.
Angry IP Scanner
A multi-platform web scanning tool for free open source, based on multi-threaded technology, can create independent thread parallel processing for each of the remaining scan IP addresses, quickly scan the IP address, the MAC address, open port, and host name, and support the setting of the scan range and port parameters through the CIDR format. The scan results can be exported to a variety of formats such as CSV, XML,TXT, where the CSV format can be opened directly with excel and supported to export to the SQL database to facilitate network topology analysis and asset management.
Advanced IP Scanner
Reliable and free network scanners can analyze LAN. The program can scan all network devices so that you can access Shared folders and FTP servers, (through RDP and radmin) remote control computers, and even remotely close the computer. The program is not only easy to use, but also works as easily as portable. It is the preferred program for each network administrator.
