OpManager Plus represents a solid “middle ground”: it’s powerful enough to cover most common needs — network, server, bandwidth, application monitoring — without the cost or complexity (on day‑to‑day use) of ultra‑enterprise or bespoke monitoring platforms. For small to mid‑sized IT shops, growing enterprises, or organizations wanting unified visibility without too many separate tools, it’s a dependable choice.
That said, it is not “perfect” — initial set up, edge‑case device coverage, and alert/response delays need careful handling. For very large, highly dynamic, or extremely customized environments, you might eventually bump against those limitations.

Unified monitoring across devices & infrastructure — OpManager Plus lets you monitor a wide variety of devices (servers, routers, switches, firewalls, etc.), along with applications and bandwidth, all from one console. This centralization simplifies infrastructure oversight.
Automatic device discovery & wide vendor support — It can automatically scan and discover multiple devices on your network (regardless of vendor: Cisco, HP, Dell, Huawei, etc.), which reduces manual configuration and speeds up setup.
Intuitive UI with customizable dashboards & alerting — Users appreciate the user‑friendly interface, dashboards that are easier to navigate, and a strong alerting/notification system (email, mobile, etc.) that helps stay on top of issues proactively.
Comprehensive monitoring functionality — It supports monitoring of server performance (CPU, RAM, disk), network traffic and bandwidth, process/service status, and more — giving a full picture of infrastructure health.
Good value for money — Compared with many high‑end enterprise monitoring tools, OpManager Plus offers a broad feature set at a relatively reasonable cost — especially attractive for small to medium‑size organizations.
Scalable for growing environments — The software can scale to monitor many devices (hundreds to thousands), making it suitable for organizations that expect to grow without immediately needing an entirely new monitoring solution.
Automation and reporting features — It supports automation (e.g. auto‑backups, threshold‑based alerts), and offers reporting and auditing capabilities — helpful for long‑term performance tracking and capacity planning.

Complexity & Learning Curve
The breadth of features means initial setup and configuration can be complex. Some users report that enabling advanced monitoring (custom device types, SNMP traps, workflows) takes time and technical effort.
Performance & Scalability Issues at Large Scale
In large deployments (many devices or high traffic), the system sometimes slows down — for example dashboards and UI may lag; browser-refresh delays or sluggishness have been reported when exporting reports or monitoring many devices.
Alerting / Reporting Limitations or Inconsistencies
Some users note that alert notifications can be delayed or unreliable at times, especially under heavy load. In other cases, bandwidth or traffic‑analysis reports may show inaccurate or inconsistent data, which impacts capacity planning or troubleshooting.
Device / Protocol Coverage Gaps
While device-discovery is generally good, there are occasions where new or less-common devices (or those not in the built-in database) get only limited monitoring (e.g. only basic “ping / ICMP” rather than full SNMP/flow), or require manual configuration.
Licensing Complexity & Cost at Scale
As network size grows and more devices/modules are added, licensing cost and management become non-trivial. For smaller or home‑lab setups, the full‑version license may feel overkill; for large enterprises, cost can escalate as device count and optional modules grow.
Upgrade & Update Challenges
Some users said that updating the software (to new versions) or installing patches can be difficult, especially if one is a few versions behind — this can lead to downtime or configuration issues if not carefully managed.
Limited Integration / Third‑Party / Cloud Focus
For organizations that rely heavily on cloud services or need deep integration with many third‑party tools, OpManager Plus can feel lacking. Some integrations require manual effort or scripting to get working properly.
UI / Usability & Customization Constraints
While basic dashboards and monitoring are often fine, customizing certain views or reports can be limited or unintuitive — users report that visualizations or report‑export features might not meet advanced or very specific requirements.

One of the major use case where we use ManageEngine OpManager is basically for monitoring application consumption of resources before putting it to production. This helps in knowing how much resources and mission critical application would need for working as expected. Further, another use case is for network packet monitoring and bandwidth consumption monitoring. We get alerts as soon as the bandwidth choke starts. This helps us in identifying the root cause and hit the exact point of issue. Also whenever the file system gets full, we get notifications, and hence we act on it on priority and remove unnecessary files to clear space.

ManageEngine OpManager provides a good option to system administrators as they can monitor all the infra devices through a centralized terminal having OpManager. The OpManager has the capability to monitor infra devices like servers, firewalls, routers, switches and more. The CPU utilization, memory utilization, space utilization, bandwidth utilization all can be monitored from one place. If any such resource utilization crosses the threshold limit, alerts are sent to the respective mail ids. We are using it on daily basis for monitoring. Whenever the application usage increases, this increasing the resource consumption, the same can be monitored and notified by OpManager to the concerned officials so that the required actions can be taken. It not only provides you with real time monitoring but also the historical data can be monitored and decisions for increasing and decreasing the resources can be taken based on the statistics.

The OpManager is a great option for monitoring, however monitoring large number of devices requires higher compute of the server on which the OpManager is used. Further, configuring the advanced features requires trained system administrators. Integration support is available, however Third party integrations require efforts.
