Monitoring Tools in Linux
There have been great strides in improving the performance of network devices thanks to tools such as routers, switches and connectors. However, slow network connections are sometimes inevitable and not knowing the cause of network issues is frustrating for sysadmins and harms the entire IT organization. For Linux users, it is particularly important to understand how the operating system executes data transmission because with that knowledge, you have greater insight into the type of tools that can properly monitor and diagnose your system’s network. If you are a Linux admin who is running into performance issues, here are several useful monitoring tools existing in Linux that will provide a complete overview of your network status.
One of the most popular Linux commands, the ip command organizes and manages the network by assigning an address to a network interface and configuring network interface guidelines. This gives you direct access into the health of your network as well as the ability to control routing, devices, and tunnels. With the advantage of performing multiple network admin tasks instantaneously, the ip command is a powerful way of monitoring your system’s network and making the necessary changes to solve any problems.
The ip link displays link layer information, activates/deactivates a network interface and offers other detailed information regarding your network devices. By being able to view link layer characteristics and manipulate devices to your liking, the ip link command provides you with a wealth of network data and full control of your Linux system, which are both crucial when working to monitor all aspects of your infrastructure.
Netstat is a utility that shows all the network connections that are running with your system. With numerous statistics including routing tables, interface statistics and multicast memberships, Netstat can be a helpful Linux monitoring tool for finding bottlenecks or network issues occurring within your environment.
By being able to display and modify your network driver/interface card, Ethtool can help achieve several tasks such as identifying/diagnosing Ethernet devices and controlling the queue selection process for multi-queue devices. These capabilities are particularly helpful when tuning your network and ultimately, Ethtool plays an important role as a monitoring tool within Linux.
