Network Monitoring with Proactive Maintenance

Network monitoring has a function that is very important for network communication that you have. Is it goes down, or other involvement occurs. Network monitoring is very useful for problems if this problem occurs so that it can save time and money. There are now many network monitoring applications or tools that you can get free or paid for. The level is different and the average network monitoring is at a reactive maintenance level and there is also proactive maintenance.

Reactive maintenance also known as breakdown maintenance that repairs the damage is then returned to normal operation by repairing or replacing damaged components and tools. While proactive maintenance, In other words, it can see further if there is damage so that it can take action before this happens. After seeing the explanation above, reactive maintenance and pro-active maintenance have their respective advantages. There are several networks monitoring that are already at the level of reactive maintenance and proactive maintenance. One of the networks proactive maintenance is NetMonk from Ketitik.

NetMonk is a network monitoring from Indonesia that has been proactive. Unlike other network monitoring applications, NetMonk has several features that other applications do not have. These features include NetMonk using notifications from Telegram applications that use far more efficiently and practically than using SMS notifications or emails that are at risk of spam. But NetMonk also uses email as a notification. The dashboard features are also very informative and easy to understand. As in the picture below.

From the picture above, there are several boards such as device status, link utilization, gateway status, CPU, RAM, and storage. Through the board above, and can find out the status that is happening. For example on the status of the board device, information about Up and Down. It is known that the number dropped by 9 and that rose 6. Why on this board there is only a list of devices that just dropped? This is because the devices that come down are more important to be repaired immediately. NetMonk has the filtering feature as above which is very useful for engineers in its use. NetMonk, is network maintenance that can see network traffic information and as the best monitoring tool you can choose. To see first hand how NetMonk works, the network monitoring application in Indonesia, visit our website and see the demo directly.

Open Sources in NetMonk

The term open source is no stranger to developers and engineer. Open source is referring to a program that its source code can be changed freely, modified, and copied as much as possible by user or developer. Not only that, but the user also can use it for any purposes. However, you must follow the rules because open source is a sign of certification from the OSI (Open Source Initiative). The example of open source software is Ubuntu Linux. Unlike open source, you can not use close source freely because you can not get the source code. The example of this close source software is Mozilla FireFox, Chrome, and the popular one is software Microsoft Windows.

What is API?

The API stands for application programming interface is a software that can receive calls or requests from other software such as applications and websites that provide services. In other words, the API is a software that allows or connects two applications. Not only that the API is also used to create software and applications by developers. You can find APIs in everyday life such as when you book a hotel, send messages, order food online or when downloading software. How did this happen? The process is like this when you use the application or do the activity, the application connects to the internet and sends data to the server. After that, the data is taken and translated by the server which then takes the necessary action as a result and then sent back to your smartphone. After receiving the data, the application translates it and then provides the information you want in an easy-to-read way. With the API all can run smoothly and make it easy.

Network Traffic Analytics

In conducting network traffic analytics, an engineer or network administrator can see the whole and analyze the network for the purpose of security, management and or general network operation. The main purpose of network traffic analytics is to get a deeper insight into types of traffic network, network packet or data that flows through the network. Besides that, network traffic analytics also can be used to understand the operation, dangerous packet, suspicious network traffic, upload, and download speed, and content by a network administrator and network security staff. Not only that, but the attacker also use network traffic analytics to analyze traffic pattern for break through and retrieve data.

Following are the advantages of network traffic analytics :

  1. Download and upload speed
  2. To understand network utilization
  3. Real-time network data analysis

Dashboard from demo NetMonk

As well as NetMonk by Ketitik, you can conduct it as a network traffic analysis tool which is easily and efficiently to use. In NetMonk, you will get which status information up and down on your device. But on the dashboard, as you can see the pictures above, you will find the complete information about the number of your devices that are down. Why? It is because the network device data that is down is more important so that it can be immediately followed up for repairs. You can also see the link utilization, gateway status, CPU, RAM, and storage. To see how NetMonk works in full, you can see the demo first and learn it from there.

NetFlow Data

In the previous article discussed NetFlow broadly like what is NetFlow, what data can be found in NetFlow, the history of NetFlow and lastly is why do you have to use NetFlow. To recall, NetFlow is a protocol that helps engineers to collect metadata on IP (internet protocol) network in switch or router. Still related to NetFlow topic, this article will discuss the use of data in NetFlow as mentioned before. Following are the explanation of data NetFlow.

What Is NetFlow?

In network monitoring, the engineers must be familiar with NetFlow term. What is NetFlow? NetFlow is a protocol developed by Cisco System that is used to collect the metadata on IP network in switch or router. NetFlow can be utilized by a network operator to determine network throughput, traffic congestion on certain interface level and packet loss. Not only that, but you can also browse deeper into the network traffic you have, to find out where the network originates and where it ends.

NetFlow has some variants include sFlow, IPFIX and owned by several vendors like XFlow, J-Flow, and NetStream. In NetFlow, there are 3 important components such as exporter, collector, and application.

The following are data that can be found in NetFlow record:

  1. Input and output interface numbers
  2. Packet and byte counts
  3. TCP flags and encapsulated protocol (TCP/UDP)
  4. Source and destination TCP/User Datagram Protocol (UDP) ports
  5. BGP routing information (next-hop address, source autonomous system (AS) number, destination AS number, source prefix mask, destination prefix mask)
  6. Source and destination IP address
  7. Type of service (ToS)
  8. Start and end timestamps

These NetFlow data are metadata that have been collected and stored by the collector in the form of records determined by the protocol.

The History

NetFlow is developed by Cisco System in 1996. This is based on Cisco’s need to understand their bandwidth usage in detail which SNMP doesn’t have because it only networks device monitoring without detailed traffic. In 2003, NetFlow version 9 chosen to be the Internet Engineering Task Force or IETF which purposes internet standards especially TCP. Recently, NetFlow becomes the main standard device in switch and router which produced by Cisco or another producer. Before NetFlow existed, to monitor network and internet on LAN and WAN, the network administrators and engineers still used SNMP.

Why NetFlow?

By using NetFlow, network monitoring become more detailed and clearer. As explained above, NetFlow is a protocol that has a better way of monitoring networks compared to SNMP. For example, NetFlow can retrieved data up to layer 3 while SNMP only retrieves data up to layer 2. The point is NetFlow can retrieve more data than SNMP. It makes it easier for the engineer to knowing where the traffic network is originated etc. This is proof that the performance of NetFlow is more sophisticated than SNMP.

The Differences Between SNMP and NetFlow

In order for network performance to work properly, the effectiveness of network monitoring and traffic management are important. In network monitoring, SNMP stands for simple network monitoring protocol and NetFlow has different ways of monitoring. Both have advantages and disadvantages of each. What makes it different? This article will discuss the differences between SNMP and Netflow.

What is SNMP?

SNMP (simple network monitoring protocol) is a protocol for equipment management that is connected in an IP (Internet Protocol) network. SNMP can be used for standard network monitoring while NetFlow is specifically for monitoring, analyzing and gathering network traffic. To collect bandwidth, monitor router bandwidth usage, switch port-by-port, device readings and network usage data are the most common uses of SNMP.

What is meant by NetFlow?

NetFlow is an application that used to monitor the type of traffic and the amount in bytes, either from or to a network router interface. The main function of NetFlow is source and destination, type of port, bandwidth used in a particular network system, delivery time and recipient. For network engineers, NetFlow is very useful for analyzing irregular that occurs when traffic passes from or to a router. Whereas in its use, NetFlow is limited to IP traffic only.

The differences between SNMP and NetFlow

  1.  SNMP can be used for real-time monitoring even every second while the time shown by NetFlow is not real even though it gives start and end times for each flow.
  2.  To collect CPU and memory usage are things that can be found when using SNMP which cannot be found on NetFlow because it is not yet available.
  3.   Notification made by NetFlow about bandwidth usage is too long-winded when compared to SNMP.
  4.   SNMP is used for standards as described above while NetFlow is used for higher traffic network.

To choose between SNMP or NetFlow, you should first look at the conditions that belong to your network device. Both have advantages and disadvantages. So that after reading this article, you can choose the right one for your needs. If you want to choose the right one for network monitoring, Ketitik, network monitoring application in Indonesia has the answer for you. Visit our website for more information.
