Pros & Cons of ManageEngine OpManager: Analysis of A Leading IT Management Platform

Computer networks—and thus IT management platfomrs—form the backbone of any organization’s IT infrastructure. And if your business is determined by online presence, the integrity of your computer networks could very well mean the success or failure of it. You simply could not afford to have end users turning away because of network-related issues. With this in mind, monitoring and improving network performance becomes absolutely essential to keep your business up and running at all times. This will ensure that service level agreements (SLAs) are maintained and prompt the swift and smooth delivery of business critical solutions.

As network is prone to many errors that can seriously impact its performance, it is necessary for it to be proactively monitored in order to detect network performance issues and prevent mishaps, thus ensuring the smooth functioning of critical applications. Proactive monitoring involves diagnosing and troubleshooting network issues before they are evident to the end user and actively eliminating threats.

A typical network monitoring and troubleshooting process should have the following flow:

OpManager offers comprehensive network monitoring capabilities that help you monitor network performance, detect network faults in real time, troubleshoot errors, and prevent downtime. Being a powerful network monitor, it supports multi-vendor IT environments and can scale to fit your network, regardless of its size. Monitor your devices and network to gain complete visibility and control over your entire network infrastructure.

Real-time network monitoring

Example of OpManager’s real-time statistics on device CPU and Memory Utilization.

Monitor network devices’ performance in real time via live dashboards and graphs. Measure critical metrics like packet loss, errors and discards etc. With OpManager’s real-time graphs, administrators get real-time statistics on device CPU and memory utilization, up-to-the-second information on any performance metric of a device and real-time traffic / bandwidth utilization of an interface/ port.

Total network performance management

OpManager offers a proactive network monitoring solution, making it easy to resolve network outages quickly and take control of your network. With OpManager, it is now easy to monitor the health of all network devices, gain visibility in network traffic patterns, automate network change and configuration management, analyze and troubleshoot WAN issues and monitor and troubleshoot VoIP performance.

Monitoring WAN Links Proactively and Ensure High Network Availability

OpManager actively monitors link latency and link errors and assigns threshold alerts to these, so you can identify degradations early and avoid costly downtime. Alerts can be sent as emails or text messages that contain details on thresholds breached and relevant link details.

OpManager’s reporting functionality also provides you with a detailed availability report of all your interfaces. You can use these reports to cross-check whether your SLAs are being met.

Real-time physical and virtual server performance monitoring

OpManager monitors various performance metrics such as CPU/Memory/Disk utilization up to a minute interval. It provides a graphical view of these metrics to monitor and measure server performance, in real-time. It also allows you to drill down to a particular time interval to understand more about the issue and take necessary actions proactively so that you can fix it before it causes serious damage to your business. It periodically monitors servers via SNMP and WMI protocols to ensure that they are up and running at their optimum performance level, 24×7. It stores all the data for historical performance tracking and troubleshooting, thus eliminating the need for multiple server monitoring tools.

Easy-to-use bandwidth traffic management software

Network traffic visualization in OpManager

Automate network mapping: visualize and pinpoint network outages and performance degradation

When the number of monitored devices increases and when companies expand to multiple locations, it becomes impractical to maintain a static network map. Further, referring to a fixed network diagram in the event of a network failure or performance degradation is highly complex and an unwholesome experience. OpManager reflects the latest device and link status with color coded icons in the network maps, acting like a live Visio diagram that lets administrators

Manage IP address and map switch port like never before

OpManager easily shows IP usage in the network.

OpManager’s IPAM & SPM Add-on brings you an integrated centralized console for IP address management and switch port mapping, giving you extensive details to track each IP address, integrate with active directory, and fetch past information related to any particular IP address. Meanwhile, the powerful switch port mapper presents better visibility of switch ports, allowing you to map devices plugged into each switch port in real time, gain historic information as you do with the IP address, have in hand a superior search capability, group switches for easy control, and get notified for any switch port changes.

Extensive monitoring and management of RAIDs

Storage Capacity Forecast by Growth Trend

OpManager provides comprehensive storage capacity details of your storage devices and do so continuously over time. These data points are then used to predict the capacity consumption in the future. The data growth trend can be analyzed using this report and exact capacity predictions can be made for the future.

Storage Capacity Forecast by Utilization

OpManager lets you make critical forecast on need to expand storage based on current and historical usage.

Forecasting storage capacity requirement is important. But it is equally important to plan your storage spending. This involves buying specific device drives to add capacity to your storage setup. Storage capacity forecast by utilization report gives you the exact dates, based on historical trends, when your devices will reach 80, 90 and 100% of their allocated storage. Planning your storage capacity buys just got better.

Resolve data center management woes once and for all

Monitoring data center performance—a synergy of server performance (both physical and virtual), application performance, and sufficient bandwidth, is a great challenge. The challenge rises multifold when disparate monitoring tools are used. OpManager rises to the challenges through real-time physical and virtual server monitoring, in-depth application monitoring, flow-based bandwidth monitoring and data center environment monitoring.

Scalable Network Monitoring

The Enterprise Edition of OpManager is designed to manage fault and performance of large networks. Enterprise networks are dynamic and keep expanding based on need, and administrators are required to provision for future growth as well. Deploy multiple Probes to distribute the load across servers and gain in-depth visibility into your network performance. Spot bottlenecks efficiently and minimize downtimes. Manage many interfaces per probe by deploying either in the same site for scalability, or in remote sites for geographically distributed network monitoring. Manage all resources either from a local console or an unified console at the NOC.

Network monitoring failover and failback

You trust your network monitor to keep you in total control of your network every second of the day. Since every single network incident – device sickness, unhealthy bandwidth levels, DoS attacks etc., is immediately brought to your notice, you are in a position to act quickly preventing business-affecting repercussions.

OpManager’s failover and failback functionality ensures an always-monitored network environment with the database also having a secondary copy that is ready to be switched to primary mode anytime.

Multiple integrations as they appear in OpManager dashboard.

OpManager Plugins and Add-ons enable administrators to extend the functionality of network management and server monitoring to meet business needs. Further the integration with other ManageEngine products provides the flexibility to manage other aspects of IT network management viz. Helpdesk, Firewall log analysis et al. For third-party integrations, OpManager gives you REST API, and of course you have the vast library of other ManageEngine applications that you can mix and match with OpManager any time.

Work-around on minor issue of network automatic setup

While you will hardly find  issue with ManageEngine OpManager, automatic setup of multiple devices across various network addresses may confuse the system. When this happens, you have to delete the device it setup from OpManager and manually add it as the type of server that you want monitored. The next upgrade of OpManager should take care of this minor issue.

Cloud-based OpManager?

As excellent as OpManager is, many would wish it to have a cloud-based version. As it is, ManageEngine is on-premise only—though ManageEngine is not without a superb application for cloud-based IT management.


From the foregoing, it’s easy to see that with its rich features, there are more pros than cons in our presentation of pros and cons of ManageEngine OpManager. In fact, you will learn once you try or purchase it that the application has a lot more to offer than the ones we ventured to list here.
