Manage Engine Adminstrator

The tool offers strong visibility into device performance, easy troubleshooting through alerts and dashboards, and supports a wide range of devices in multi-vendor setups. While the initial setup and some advanced configurations can be a bit complex, once implemented, it significantly improves network uptime, reduces manual effort, and delivers good value for money for day-to-day operations.

Additionally, some advanced features require extra licensing, reporting customization is limited in certain cases, and performance may slow down when managing a large number of devices, with support response times occasionally being slower than expected.

System Engineer

If I had to choose one con, it would be the on-going maintenance of detected systems where agents are or previously were installed, specifically in the case where a system has been renamed, it doesn't always clean up the old record in a timely manner, leaving duplicate entries for the same system.

Chief Technology Officer

It is a robust platform that has ability to capture even the intricate sensor that may seem difficult to capture (i.e. CPU cycles, Memory slacks etc.) very important from the performance and security standpoint.

Manager - IT

ManageEngine Opmanager is a user-friendly, scalable network monitoring tool that offers real-time device monitoring, automated alerts, cutomized reports, and strong integration with other tools.

Network Security Engineer

The device management and asset visibility features are also helpful, allowing us to maintain an inventory of network devices and track their status from a single dashboard.

IT-Manager

The platform provides a comprehensive and intuitive approach to network monitoring, offering strong visibility into devices, performance metrics, and potential issues.

Assistant Manager

It provides real-time visibility into the entire IT infrastructure—including servers, routers, switches, and virtual environments—through a single dashboard.

In terms of cloud and modern network environments like Cisco Meraki, the tool has limited native integration, and deeper visibility often depends on APIs, which adds complexity.

System Adminstrator

The overall value, ease of monitoring, and performance insights make it a good option, especially for businesses looking to minimize downtime and control network health in a single dashboard, even though the initial setup and configuration may take some time.

Senior Officer, Networking

What I liked most about OpManager was its user-friendly interface and real-time monitoring, which made it easy to track network performance and quickly respond to issues.

Additionally, the customization options for dashboards, alerts, and reports make it easier to align monitoring with operational requirements.

OP-Manager delivers strong reliability, flexibility, and insight, making it a solid choice for organizations looking to improve their network monitoring and infrastructure management.

IS Engineer

OPManager has robust capability in monitoring. Either in hardware (CPU, RAM and Disk utilization), services, applications or network monitoring.

NOC Analyst

Some advanced features can be complex to configure, especially for new users and custom reports require additional fine-tuning also initial setup for advanced monitoring may take extra time.

The customization and reporting capabilities support operational needs, and once configured properly, it becomes a stable monitoring solution.

Assistant Manager IT

Device discovery via SNMP isn’t always accurate on the first attempt, requiring multiple rescans or manual adjustments to get all devices added correctly.

Senior Technical Support Executive

It helps us monitor network performance, reduce downtime, and quickly identify issues.

Lead Engineer

Ability to build custom dashboards, business views, and detailed performance reports

Systems Engineer

It has been great in terms of metric monitoring for our on prem infrastructure and integration with alarms one is helping us alot

It helps me monitor servers and network devices easily, and the alerts are reliable.

Senior Software Development Engineer

Monitoring VM performance metrics in alignment with the host system stats is a big plus that contributed to better management of hybrid systems.

The setup is simple, and the dashboard makes it very clear to see the health of all servers and network devices in one place.

Initial deployment and fine-tuning of alerts, thresholds, and templates can be time-consuming and require experience.

Systems and Network Supervisor

I found the user interface of ManageEngine OpManager to be somewhat cluttered and not very intuitive, making navigation challenging at times.

Overall experience has been very positive becasue its provides strong visibility across the entire network and makes monitoring devices, servers, and bandwidth easier.

Easy setup, clean dashboard, accurate alerts, great device visibility, and smooth network/server monitoring with minimal effort.

Senior Engineer

It takes long time to scan the device during device onboarding than onboarding of multiple devices at a time.

IT Engineer

some tasks in op manager involve multiple navigation steps , and new user may require training due to product's complexity.

Tech System Specialist

The initial setup is relatively straightforward, and the dashboards and visualization tools are helpful for both monitoring and reporting.

Sysadmin

All-in-One Dashboard: Monitors servers, switches, and firewalls in one place.

Infrastructure Engineer

We have benefited from features like WAN RTT monitoring and VoIP performance tracking since it has provided us with information on areas that cannot be measured.

IT Support Specialist

It provided clear insight into the service response time, packet losses, and memory consumptions which enabled me to adjust the servers’ setups when the traffic was high.

IT Services Manager

Its intuitive, customizable dashboard simplifies the visualization of key metrics and alerts, enabling swift and proactive issue resolution.

Senior IT Engineer

OpManager’s alerting system enables us to set specific performance levels and the software raises an alert when these levels are crossed.

Functional behavior I found was inconvenient was that when adding very large vmware clusters, it sometimes required further configuration to get performance counters perfectly synched across each node.

IT Director

Some of the proactive monitoring attributes of OpManager include the threshold-based alerts and performance trend analysis which helped in early warning signs for risks.

In my case I utilized it in association with a VMware environment, and was impressed with its ability to identify hosts and VMs while monitoring the CPU, memory and disk usage among others.

Applications and Packaging Specialist

A standout attribute of this product is its ability to provide a consolidated overview of all equipment in a single location, enabling effortless monitoring of network status.
