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.
So


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.
