Using analytics on network devices can allow us to find out information about “who, what and why” is active on the network. This information can be used to improve performance, maintain security, and general network management.

Not all analytics on network devices provide sufficient and effective information to solve network problems. This is because tools to help analyze network traffic based on data flow only provide top-level information. For example, IP (Internet Protocol) addresses and traffic volume. To be able to monitor activity and analyze network traffic thoroughly, you need specialized tools, including:

1. SNMP (Simple Network Management Protocol)

Through a specially designed simple protocol, users can monitor and manage computer networks remotely using a control center. You can obtain network device data or information about the status and conditions in the network when using SNMP.

This protocol uses UDP transport, specifically on port 161. Network management is operated by collecting network device data and determining the variables in the network used. The network management monitoring process is performed from a PC that acts as the network management station of the SNMP agent.

Furthermore, the results of network management monitoring will be displayed in a graphical form that shows fluctuations in network traffic or traffic. SNMP is a very important mechanism in network monitoring and has several components, namely:

Managed devices: Nodes on the network that support SNMP and access to certain information.

Agent: software that is part of the monitored device. The agent has access to the device’s MIB (database information management) and allows the NMS system to read and write to the MIB.

Network Management System (NMS): an application in the system that monitors and controls devices managed through agents using SNMP commands.

2. Web GUI

Web GUI is used to monitor and monitor graphical displays in the form of graphical fluctuations and network traffic. Web GUI can be easily used because it is easy to read and understand due to the website-based interface.

We don’t need to type in special commands or syntax that only a number of reliable network engineers can understand, because the website-based interface makes everything look easier to use and read.

3. Ping

If a network engineer wants to test the reachability and availability of hosts on an IP (Internet Protocol) network, then the tool to use is Ping.

Through one of the basic instructions that a network admin must master, Ping results can be viewed to determine whether a host on the network is active or not. In addition, Ping can be used to measure transmission time and packet loss when communicating with a hosts.

4. Syslog

Syslog is different from Windows Eventlog. Syslog is a messaging system that allows devices to send event notifications to an IP (Internet Protocol) network. Information from these messages can be used for network management and network security monitoring. Syslog can support a variety of devices ranging from printers, routers, to firewalls.

5. Utilizing Script Strength

On networks where there is no Network Management System (NMS), or a Network Management System (NMS) that does not have certain features, network administrators can use scripts. The script can utilize commands commonly used in the IT networking world.

For example Ping, Lynx, SNMP Walk, and others. Scripts are supported by almost network elements to run certain programs. For example, collecting information, making changes to design configurations, or displaying special programs that have been scheduled. Bash scripts, Perl and others are tools for writing scripts that are commonly used by network admins.

Based on these specialized tools, TITS uses SNMP in its web-based application NetMonk, a network monitoring application. Using SNMP allows NetMonk to find the latest information about device conditions. Want to know more about NetMonk? Read the NetMonk article.
