18.WifiCutout Landscape

With digitization conquering businesses, maintaining data and network security health standards and providing the best experience to clients and end users is essential. Today's networks are, for the most part, comprised of Linux and Windows-based environments. Businesses with data centers often prefer Linux networks, as they are good at scalability, security, customizations, consistency, and flexibility.

For these Linux-based networks to perform at their best optimum levels, tracking their health and availability with a Linux monitoring tool is essential. The primary functions of a Linux network monitor include:


  • Maintaining an inventory of your Linux-based devices.
  • Giving real-time status updates. 
  • Spotting traffic congestion in the interfaces.
  • Providing insightful reports on the network performance of Linux-based systems.

While so many Linux monitoring tools are available in the IT market, ManageEngine OpManager stands out for its holistic and dynamic nature.

OpManager: The Powerful Linux Monitoring Tool

OpManager is a potent and dynamic Linux network security threat monitor that scrutinizes all the Linux-based devices accessed. Its threshold-based monitoring also prevents constantly-rising performance and bandwidth-related network security issues. 

OpManager's Linux Monitor 

The key Linux monitor features include:

  • Intuitive discovery: To maintain a network inventory of Linux-based systems
  • Real-time monitoring: To gain instant device status updates
  • Fault management: To manage network security issues efficiently
  • Advanced Reporting: To oversee the network performance of Linux-based devices 

Intuitive Linux Device Discovery

With the constant addition of new devices to your Linux network, manually adding devices and configuring threshold levels for them can be challenging. OpManager provides a feature called "Scheduled Discovery" that runs an automated cloud security scanner periodically to find changes in the network, like the addition or removal of devices and updates in the inventory. With the help of OpManager's Linux device templates and Discovery Rule Engine, you can also automate associating performance monitors to these discovered devices.


Real-time Linux Network and Server Monitoring 

Your Linux data and network security and health are crucial for the individual devices and servers in the network to perform at their best. Servers need to be monitored in real-time since any outages in the server can directly impact network performance and end-user experience. OpManager keeps this in check by monitoring Linux devices and servers in real-time. With more than 2,000 metrics to monitor network performance, OpManager's Linux monitoring is everything you can rely on to thwart performance and network security issues. Hence, you retain control of your Linux system.


Linux Network Traffic Monitoring

You can leverage OpManager's Linux monitoring to track traffic flow and identify network congestion in your Linux network. This helps you better manage I/O requests and ensure all Linux network operations continue uninterrupted. You can monitor network traffic in the interfaces of Linux servers, switches, and routers, track the servers' response time, and identify and fix network lags before they affect end users.


Fault Management for Linux Devices

OpManager's Linux monitoring solution performs fault management through active alerting and automating L1 and L2 troubleshooting tasks. L1 refers to an engineer who is troubleshooting, and L2 refers to who is responsible for troubleshooting tickets to detect problems that may arise.

Active Alerting  


OpManager uses different network monitoring alerts when any Linux device's set threshold level is breached. These alarms are called  Attention, Trouble, and Critical. They are based on the severity of a cloud security breach, determining how quickly you need to act on the network security threat. This way, you can prioritize and troubleshoot network security issues that require immediate attention. You can also configure these alarms to escalate or alternate people if the notification goes unattended. This ensures that no critical faults will be left unresolved or impact Linux network performance.

Intelligent Automations  


Sometimes, an on-field team will rush to a situation only to learn that troubleshooting could have been done remotely. In other cases, network admins perform routine maintenance tasks manually to ensure the health of the Linux network, which can become repetitive and time-consuming. Automation is the key to saving IT admins' time and effort. OpManager's Workflows feature automates specific L1 and L2 troubleshooting tasks that no longer require manual intervention. Now, all you need to do is define the criteria needed to execute the required actions, and then you drag and drop the desired Linux devices into the Workflows feature. This lets you focus on critical tasks and automate the rest. 

Advanced Reporting

With over 100 reports on network health, availability, hardware metrics, network and applications performance, and more, OpManager helps you stay resourceful and performs historical data analysis to understand data security trends and growth patterns. This cloud security framework analysis helps you forecast when CPU usage spikes or if no free space is left. In other words, you can plan your storage capacity to ensure it upgrades well and avoid potential CPU/memory issues and indiscriminate storage purchases.


Built-In Linux Troubleshooting Tools

OpManager's Linux monitoring has a built-in network security toolkit that aids in quicker Linux network security threat troubleshooting, such as :

  • Ping Tool
  • Traceroute
  • CLI Tool
  • SNMP Tool
  • MAC Address Resolver
  • DNS Resolver
  • DHCP Scope Monitor
  • Port Scanner
  • And more
