# Linux Network Monitor Keep your Linux network readily available with OpManager ![Linux Network Monitoring Tools - ManageEngine OpManager](https://i.ytimg.com/vi/XaiR9BM3btw/hqdefault.jpg) Businesses depend on their network infrastructure to deliver digital services to clients and end users. These environments include Windows and Linux networking devices. Windows networks with their GUI are relatively easy to manage while Linux networks provide greater flexibility and advanced levels of customizations compared to Windows networks. Since operating systems help the deployed applications interact with the hardware, you should choose the OS depending on your business needs and your IT team's expertise. Often, businesses like data centers lean towards Linux networks, as they are good at: 1. **Scalability**: Exceptionally scalable. 2. **Consistency:** Consistent with their operating model across all distributions. 3. **Customization**: Easily customizable, because of their freely available source code. 4. **Security**: More secure from cyberattacks. 5. **Cost-free**: Free of licenses (but may include support costs). Although Linux networks are considered efficient in running applications compared to their Windows counterparts, they still experience performance and bandwidth issues, which ultimately affect their services, so what you really need is a Linux [network monitoring tool](https://www.manageengine.com/network-monitoring/network-monitoring-tools.html). With a feature-rich Linux network monitor, you can keep in check the Linux network environment by tracking the network for its availability and health. ## What do you need in Linux network monitoring? The fundamental reason behind performing Linux network performance monitoring is to know your network's state at any given point, so you can maintain and improve your quality of service (QoS). To better understand the state of your Linux network, an IT admin must: - Maintain an inventory of all your Linux devices. - Know the real-time state of your Linux devices. - Identify traffic congestion in the interfaces. - Get insightful reports on the performance of Linux devices. While there are tons of [network monitoring tools](https://www.manageengine.com/network-monitoring/network-monitoring-tools.html) for Windows, there are only a handful of network monitoring tools for Linux that can do everything mentioned above. One such powerful Linux [network monitor](https://www.manageengine.com/network-monitoring/network-monitor.html?linux) is OpManager. ## OpManager: A powerful Linux network monitor tool [ManageEngine OpManager](https://www.manageengine.com/network-monitoring/) is a highly scalable and powerful **Linux network monitor**. It monitors all the Linux devices in your network for availability, health, and performance in real time. Using OpManager, a potent Linux network traffic monitor, you can monitor Linux network traffic, generate Linux network performance reports, and automate routine tasks. ## How to monitor network traffic in Linux with OpManager - Linux inventory - Real-time monitoring - Traffic monitoring - Fault management - Automation - Advanced reporting ### Linux network inventory Your Linux network is ever expanding and constantly evolving. New devices are added every day into the network. Manually adding every device and configuring thresholds for new devices is an exhausting task for an IT admin. Keeping this in mind, OpManager - a Linux network management software is designed to automatically scan and add devices into the Inventory with the help of [Linux device templates](https://www.manageengine.com/network-monitoring/device-discovery/linux-performance-monitoring.html). Further, you can configure the Discovery Rule Engine in OpManager to automatically associate performance monitors to discovered devices. ![Linux Network Monitoring - ManageEngine OpManager](https://www.manageengine.com/network-monitoring/images/linux-network-inventory.png) ### Real-time network monitor for Linux Your Linux network's performance is dependent on the performance of individual Linux network devices. Faults need to be identified in real time with a Linux network performance monitor, so performance issues can be fixed before they impact end users. Using OpManager's Linux based network monitoring, you can [monitor the availability](https://www.manageengine.com/network-monitoring/availability-monitoring.html) and performance of Linux devices in real time (up to one-minute granularity). OpManager offers more than 2,000 metrics for monitoring network device performance, which helps you instantly identify performance issues. With OpManager's **Linux network monitoring**, you can monitor the network traffic in real time. ![Real-Time Linux Network Monitor - ManageEngine OpManager](https://www.manageengine.com/network-monitoring/images/real-time-linux-network-monitor.png) ![Linux Network Monitor Tool - ManageEngine OpManager](https://www.manageengine.com/network-monitoring/images/real-time-linux-network-monitor1.png) ### Linux network traffic monitor When the Linux application servers in your network are unable to handle incoming requests, the user experience is negatively impacted. This could be due to network congestion, which creates the need for Linux network monitoring. Using OpManager as a Linux network traffic monitor, you can monitor the traffic in the interfaces of Linux servers as well as switches and routers. You can also monitor the response time of the servers, which helps in identifying network lags in [Linux server monitoring](https://www.manageengine.com/network-monitoring/linux-server-monitoring.html?linux-network-monitor). ![Linux Network Monitoring Software - ManageEngine OpManager](https://www.manageengine.com/network-monitoring/images/linux-network-traffic-monitor.png) ### Intelligent Linux network fault management **Linux network monitoring tools** raise alerts to inform IT admins about network faults, but not all alerts require an IT admin's attention. To help you immediately identify show-stopping alerts so you can quickly act on them, OpManager categorizes [network monitoring alerts](https://www.manageengine.com/network-monitoring/network-monitoring-alerts.html) into Attention, Trouble, Critical, and Service Down. This way, you can prioritize alerts and troubleshoot the crucial ones first. ![Network Monitoring Tool Linux - ManageEngine OpManager](https://www.manageengine.com/network-monitoring/images/intelligent-linux-network-fault-mgmt.png) ### Linux network automation There are certain routine tasks to be executed by an IT admin to maintain a healthy network.
