Frequently asked questions

  • Standalone
  • Enterprise Edition

Q. Are there any restrictions on the 30-day trial?

A. No, the trial edition comes with all functionalities and can monitor up-to unlimited devices. If you need to monitor more number of devices, please request a license.

Q. What are the system requirements for OpManager?

A. Please refer to the System Requirements page. 

Q. Am I eligible for technical support during evaluation?

A. Yes absolutely. Install a 30-day trial version and register yourself during installation to avail free technical support during evaluation period.

Q. How is OpManager licensed?

A. OpManager is licensed based on the number of monitored devices. Any device that responds to an ICMP ping can be monitored using OpManager e.g. Routers, Switches, Firewalls, Servers, UPS, printers. In a virtualized environment, every virtual instance is considered as a separate device for both monitoring and licensing purposes. 

Q. Do I need to rebuild OpManager from scratch after purchasing?

A. No, all ManageEngine products are licensed through a registered XML file. One can simply apply the license and use the same OpManager instance in production environments. One can even move the data to a different server if needed.

Q. Does upgrading to a newer OpManager version cost me?

A. No, it is absolutely free. All you need to do is, ensure you have paid the Annual Maintenance and Support fee. 

Q. If I buy more devices or add-ons or plug-ins in future, how does it work?

A. Absolutely, you can upgrade OpManager at any point of time. For instance, if you wish to upgrade OpManager 250 devices to 500 devices pack, you have to pay only the difference between these price slabs. Similarly for add-ons and plugins, you have to pay only the cost pertaining to it as per the current pricing.

The newly obtained license file has to be applied on your existing OpManager installation to enable the purchased devices pack or modules. It is not necessary to start things from scratch.

Q. Can I buy a single 250 devices OpManager license and monitor in two different locations?

A. No. The license is restricted to a single installation of OpManager and not a consolidated license for the enterprise. In such a case you have to buy OpManager Enterprise Edition for remote network monitoring or separate license for each locations. 

Q. How does OpManager monitor the devices?

A. OpManager is an agent-less monitoring and management tool that uses a wide variety of protocols and technologies: ICMP, SNMP, WMI, CLI (Telnet/ SSH), TFTP, SCP. OpManager also includes a Syslog demon, SNMP Trap listener and Flow collectors for NetFlow, sFlow etc.. All these and more bring together many network performance monitoring and management capabilities within OpManager.

Q. Which vendors are supported by OpManager?

A. OpManager supports out-of-the-box over 100 vendors. To list a few: 3Com, Cisco, DELL, HP, D-Link, Extreme, Fortigate, Foundry, Juniper, Netgear, Netscreen, Nortel, Linux, Solaris, HP-UX, IBM-AIX, Microsoft Windows, APC, Libert. 

Q. How many devices can I monitor with OpManager?

A. The OpManager polling engine can monitor upto 10,000 Interfaces. However this depends on the system hardware, polling frequency and type of devices. The OpManager Enterprise Edition can monitor upto 50,000 interfaces. To know the exact number of interfaces monitored by your OpManager installation, refer to the "About" page in the product (top right-hand side).

Q. Does OpManager integrate with 3rd party tools?

A. Yes through API. More about REST API at http://api.opmanager.com. Further OpManager integrates with ManageEngine products viz. ServiceDesk Plus, Firewall Analyzer, Applications Manager, NetFlow Analyzer and Device Expert. See more on OpManager Integration

Q. Can I Install OpManager on Linux? Is there any limitation?

A. Yes, you can install OpManager on any Linux server viz. RedHat 7.x and above, Debian 3.0, Suse, Fedora, Mandrake. However NCM plug–in supports only Windows OS and doesn’t support Linux.

Note: Installing OpManager on a Linux server will disable all WMI based monitors.

I still have some questions which needs clarification!
