# Network Fault Monitoring - ManageEngine OpManager ## Fault Monitoring Identify, locate and prevent network faults proactively with OpManager. Network fault monitoring and [network fault management](https://www.manageengine.com/network-monitoring/network-fault-management.html?fault-mon) are the big challenges when you have a small team. The task becomes more complicated if you have to manage a remote site and have to dispatch a technician to the site only to find out the problem is something you could have fixed remotely, or you could find that you don't have the right equipment and have to go back and get it, hurting your service restoration time. In most cases, the time taken to identify the root cause of a problem is longer than the time taken to fix it. ## ManageEngine OpManager: The swift fault monitoring system OpManager, a fault monitoring software, constantly monitors faults in the network devices by [network device monitoring](https://www.manageengine.com/network-monitoring/network-device-monitoring.html?fault-mon) and simplifies the process of network alert management by implementing advanced alert monitoring capabilities. Having a proactive tool like OpManager that performs fault monitoring efficiently helps you quickly identify the root cause of the problem and fix it before end-users notice it. ## Gain visibility into network faults with event-alarm correlation ![Fault monitoring software- ManageEngine OpManager](https://cdn.manageengine.com/network-monitoring/images/Alarms.JPG) OpManager's fault monitoring performs intelligent event processing in the case of [network monitoring alerts](https://www.manageengine.com/network-monitoring/network-monitoring-alerts.html?fault-mon). It correlates raw network events, filters unwanted events, and presents only meaningful alarms to the operator. It supports color-coded alarms which are presented in a user-friendly format. You can view the event history associated with an alarm and manually clear or delete alarms. ## Ensure prompt alerting with threshold-based fault monitoring ![threshold](https://www.manageengine.com/network-monitoring/images/threshold.gif) OpManager's fault monitor supports threshold-based alerting such that it alerts an operator when a service or health check counter on a device exceeds or goes below a certain limit. It performs alerting through various channels such as SMS, Email, slack messages, ticket logs, and web alarms. You can also configure OpManager to run external programs or homegrown scripts automatically when an alarm occurs. OpManager alerts the user with a sound alarm for critical notifications. It provides complete customization, allowing you to filter unwanted alerts and get notification sounds only for critical alerts. All you have to do is [configure a web alarm profile](https://www.manageengine.com/network-monitoring/help/configure-web-alarm-profile.html?fault-mon) to alert you on selective criteria based on your preference. ## Acknowledge alarms to never miss out on even a single network fault ![acknowledge-network-alarm](https://www.manageengine.com/network-monitoring/images/acknowledge-network-alarm.gif) While working on multiple alarms simultaneously, OpManager allows admins to quickly mark alarms on which they have already initiated action, much like marking emails as read or unread. Acknowledging alarms is another small but beneficial feature for network admins to keep track of new network monitoring alerts and the ones that have already been read and acted upon. It is especially helpful when more than one network admin is involved in the network fault monitoring, such that one can know the alarms that have been taken care of even when the other is unavailable. ## Keep tabs on critical variables with SNMP Trap and custom MIBS support ![network_tools](https://www.manageengine.com/network-monitoring/images/network_tools.gif) Most network devices nowadays are capable of sending out SNMP traps when a fault occurs. A good fault monitoring system should be able to support [SNMP traps](https://www.manageengine.com/network-monitoring/snmp-trap-monitor.html?fault-mon) and provide meaningful information to the admins. OpManager, a fault monitoring tool, does exactly that by providing support for basic SNMP traps out of the box. You can also add support for traps from any custom SNMP MIB. OpManager's network fault management can extract useful information that is sent with SNMP traps as variable bindings (SNMP varbinds). So if you have bought devices from different vendors, all you need to do is get access to those vendor-specific MIBS and you can easily have OpManager monitoring critical variables on that device. ## Create escalation rules to automate actions on critical/unnoticed alarms ![Alarm escalation rules- ManageEngine OpManager](https://cdn.manageengine.com/network-monitoring/images/alaramesc1.JPG) OpManager's fault monitoring software allows IT administrators and managers to set up automatic alarm escalation rules. For example, IT managers can set up an escalation rule to get a [report](https://www.manageengine.com/network-monitoring/network-performance-reporting.html?fault-mon) of server alarms that are currently open for more than one hour. This report can be periodically sent to the IT manager via email. ## FAQs on Fault monitoring ### What are the types of network faults? Some of the common network faults include: - Interference in data transmission - Network latency - Packet loss - Configuration errors - Hardware failures - High resource utilization - Connectivity issues - Slow response time - Performance degradation ### Why network fault monitoring is important? Network fault monitoring is important to ensure peak network performance and uninterrupted network operations. With constant monitoring of network devices, you can easily locate network faults and quickly act upon them to reduce MTTR and the impact on network availability. Fault monitoring helps you stay stay on top of your network by keeping you aware of network issues even before it affects your end users. ## Discover more on Fault monitoring ### Featured - [Network fault alerting](https://www.manageengine.com/network-monitoring/network-fault-alerting.html?fault-mon) - [Root cause analysis](https://www.manageengine.com/network-monitoring/root-cause-analysis.html?fault-mon) - [Network troubleshooting tools](https://www.manageengine.com/network-monitoring/network-troubleshooting-tools.html?fault-mon) ### Quick links - [Blogs](https://blogs.manageengine.com?fault-mon) - [E-books](https://www.manageengine.com/network-monitoring/ebooks.html?fault-mon) - [Videos](https://www.manageengine.com/network-monitoring/videos.html?fault-mon) - [Case studies](https://www.manageengine.com/network-monitoring/customer-recommends.html?fault-mon) - [Awards and Recognitions](https://www.manageengine.com/network-monitoring/network-software-review.html?fault-mon) - **Blog:** [VLAN monitoring](https://blogs.manageengine.com/corporate/general/2022/05/19/vlan-monitoring-in-opmanager.html?lan-mgt) - **Whitepaper:** [Event and fault management](https://www.manageengine.com/network-monitoring/event-and-fault-management.html?fault-mon) - **Help:** [Fault management and escalation](https://www.manageengine.com/network-monitoring/help/storage-monitoring-fault-mgmt.html?fault-mon)
