1：Zabbix
Nowadays, enterprises are "no monitoring, no operation and maintenance". It is unimaginable to have no monitoring means in the enterprise. Zabbix is an enterprise-level open source solution based on WEB interface that provides distributed system monitoring and network monitoring functions. Zabbix server can monitor system and hardware information through SNMP protocol, and zabbix agent can monitor system and hardware information. DELL iDRACE, HP iLO, IBM IMM, etc. can all be monitored through SNMP protocol.
2: Grafana
Grafana is an open source monitoring data analysis and visualization suite. When paired with Zabbix, it can help you query, visualize, alert, and analyze the indicators and data you care about, and achieve cool displays.
3：FinalShell
Nowadays, enterprises must use SHH to connect to hosts. FinalShell can not only connect to Linuxz hosts but also Windows hosts, and can also monitor memory, CPU performance, Ping delay packet loss, Trace routing monitoring, real-time hard disk monitoring and other functions.
4: sunflower
Nowadays, enterprises must have remote maintenance, and Sunflower is a good choice. It can remotely control mobile phones, remote desktop connection, remote boot, remote management, etc.
5：IDM
The biggest feature of IDM is its super-fast download speed, although it does not support BT/magnetic/Thunder links. But we usually go to the official website to download some software, such as system images, etc. This is much better than browsers and some download tools.
6： EVE-NG
EVE-NG supports many manufacturers including Huawei and Cisco, unlike other simulators that only support one product. For example, Packet Tracer supports Cisco equipment. By using EVE, you can build networks that require and plan for the correct design to validate the solution.
7： NMAP
nmap is a network connection scanning software, used to scan open network connections of computers on the Internet. Determine which services are running on which connections and infer which operating system the computer is running (this is also known as fingerprinting). It is one of the must-use software for network administrators and is used to assess network system security.
8: MAC Address Scanner
In enterprises, it is often necessary to count the MAC address corresponding to an IP address. This tool is a good choice. MAC address query scanner is a powerful MAC tool that can assist in device identification through the network. It is mainly used for computers, routers/managed switches/other intelligent network equipment, IPTV set-top boxes, radio and television CableModem/CMTS/two-way set-top boxes, and Bluetooth. Wait for the communication equipment manufacturer to identify.
9：Wireshark
Wireshark (formerly Ethereal) is a network packet analysis software. The function of network packet analysis software is to intercept network packets and display the most detailed network packet information as possible. Wireshark uses WinPCAP as the interface to directly exchange data packets with the network card. We can use it to check whether there are problems with the network, such as whether there are loops.
10：Graylog
Reading logs is indispensable in an enterprise. If the number is not large, we can manually check them one by one, but if the number is large, centralized management tools are needed. Graylog is a log management tool that is easy to use and has comprehensive functions. It is simple to deploy and maintain and takes up relatively small resources.
