ManageEngine OpManager is ManageEngine’s network and server monitoring product. It is licensed on the number of monitored devices, where a device is any element that responds to an ICMP ping, such as routers, switches, firewalls, servers, UPS units and printers.[2] The licence covers the device as a whole. Its interfaces, ports, disks and performance metrics are included and are not counted separately.[1] Licences are sold in device packs, either as an annual subscription or as a perpetual licence.[7] They are delivered as a registered XML licence file applied to the installation.[2] OpManager Nexus, formerly OpManager Plus, is the same product under a different licensing model. It bundles the main OpManager add-ons with the base licence.[2] On-premises use is governed by the ManageEngine EULA.[6]
Editions
The OpManager FAQ names three editions of the standalone product: Standard, Professional and Enterprise.[2]
- Standard. Applying a Standard licence requires version 124015 or later.[2]
- Professional. The former Essential edition, now renamed Professional.[2]
- Enterprise. The same functionality, built for scale and distributed networks. Probes are deployed at remote sites and report to a Central server. ManageEngine positions it for estates of more than 500 servers or 5,000 interfaces.[2] The FAQ gives a polling capacity of up to 10,000 interfaces for a standalone engine and up to 50,000 for the Enterprise Edition. These are technical limits, not licence counts.[2]
Editions can be upgraded but not downgraded. A customer can move from Standard to Professional or Enterprise, but cannot move from Professional back to Standard.[2] An OpManager Enterprise installation cannot be converted to OpManager Nexus from within the product. The Nexus build must be installed separately.[2] The store sells OpManager, OpManager Enterprise, OpManager Nexus and OpManager Nexus Enterprise as separate products.[7]
Add-ons (standalone OpManager)
The base device licence covers network devices, servers, virtual machines and basic application monitoring.[2] The FAQ lists the add-ons that need separate licences:[2]
- Network Configuration Management (NCM)
- Firewall Log Analysis
- NetFlow/Flow Analysis
- IP Address Management (IPAM) and Switch Port Management (SPM)
- APM Plugin for advanced application monitoring, which must be licensed and applied in both OpManager and APM
- Storage Monitoring, Access Points Monitoring, IP SLA Monitoring and URL Monitoring
Adding devices, add-ons or plug-ins later is priced at the current rate for the item. Moving up a pack, for example from 250 to 500 devices, costs only the difference between the two tiers.[2]
Metrics
| ManageEngine term | Catalog row | What ManageEngine says |
|---|---|---|
| Device | Device (OpManager) | OpManager is licensed on the number of monitored devices. Every virtual instance is a separate device.[2] |
| Lite device | Lite device (OpManager Nexus) | Used for lightweight devices or components: access points, availability-only IP addresses, WAN IP addresses and network paths.[4] |
| Access point | recorded under Device (OpManager) | Devices in the Wireless Access Point, Meraki Radio (MR), Meraki Vision (MV) and Meraki Gateway (MG) categories are licensed as Access Points.[1] |
Counting / floors
What is a device (as retrieved 2026-09-27). The licensing page lists routers, switches, firewalls, load balancers, wireless LAN controllers, servers, VMs, printers and storage devices, and everything else that has an IP address and is connected to the network.[1] In the vendor’s worked example, 50 network devices with 10 interfaces each and 5 metrics per device and per interface add up to 2,750 monitored metrics. All of them are covered by a 50-device licence.[1] IPMI devices are licensed separately.[1] OpManager offers no unlimited pack.[1] Catalog proof: OpManager device licence includes all interfaces, disks and metrics of the device.
Staying within the pack. If monitored devices exceed the licence, the customer can move up to a larger pack or unmanage less-critical devices to free licences.[1] The store page asks customers with more than 10,000 devices for a personalised quote.[7]
One installation per licence. A licence is restricted to a single OpManager installation and is not a consolidated licence for the enterprise. Monitoring two locations with one 250-device licence is not allowed. The customer needs OpManager Enterprise Edition with probes, or a separate licence for each location.[2] In an Enterprise (probe-central) deployment, the licence is applied only on the Central server and propagates automatically to connected probes.[2] A probe is permanently bound to the Central server where it was first registered.[2] The same restriction appears in the EULA, which bars installing one copy on more than one server.[6] Catalog proof: An OpManager licence covers one installation, not multiple sites.
OpManager Nexus
OpManager Nexus includes NCM, Firewall Log Analysis, IPAM, NetFlow Analyzer and the Applications Manager plugin in the base licence, at a discounted price.[2] Its Device pack is shared across three bundles:
- Splitting. A 100 Devices pack can activate 100 Devices of the Network bundle, 100 of the SAM (server and application monitoring) bundle, 100 of the Storage bundle, or any combination adding up to 100.[4] Devices can be moved between bundles as long as the total stays within the licence.[4] Catalog proof: An OpManager Nexus Device pack can be split across Network, SAM and Storage bundles.
- Primary Count. A bundle’s consumption is its Primary Count, the number of Devices used by the component in that bundle that consumes the most.[4] In the vendor’s example, 50 Devices in the Network bundle allow up to 50 network devices, 50 flow interfaces, 50 NCM hosts, 500 switch ports, 500 IPs, logs from 1 firewall and 100 Lite devices.[4]
- No double counting. A server monitored both in the Network bundle and in the SAM bundle is counted once, and the user chooses which bundle monitors it.[4] Third-party integrations such as ServiceDesk Plus, ServiceNow, Slack and Jira do not consume Devices.[4] Catalog proof: A server monitored in both Nexus Network and SAM bundles is counted once.
- Firewalls and users. Firewall log management is limited by pack size: 1 firewall for packs of 50 and 100 Devices, 2 for 250, 3 for 500 and 5 for 1,000. Health and performance monitoring of firewalls is not limited in this way.[4] Included users also scale with the pack, from 2 users (50 and 100 Devices) to 10 users (1,000 Devices). More are sold as an Additional Users add-on.[4]
- Add-ons. Extra Lite devices, switch ports, IP addresses and flow interfaces can be bought individually without a larger pack.[4] IP SLA monitors and the SAM add-ons, including the APM Insight agents, Oracle EBS, SAP and End User Monitoring, are extra.[4] Failover (high availability) and the Advanced Security Analysis Module are included.[4] An add-on licence bought for NetFlow interfaces is used up first, before Devices from the base licence are consumed.[4]
- Trial and renewal. The trial provides 1,000 Devices.[4] Customers who bought the earlier OpManager Plus licence pay the new Device-based subscription fee at renewal. The APM plugin is included in the new licence.[4]
Virtualization & partitioning
OpManager applies no host-based counting. In a virtualized environment, every virtual instance is a separate device for monitoring and for licensing.[2] Physical devices and virtual machines are charged in the same way.[1] A hypervisor host and each guest it runs are therefore separate devices when all are monitored. The vendor’s answer to a VM count above the licence is to move up a pack or to unmanage less-critical devices.[1] Catalog proof: Every virtual machine counts as a separate OpManager device. See virtualization and partitioning.
Cloud / BYOL
The retrieved OpManager licensing documents cover only the on-premises product. They describe no bring-your-own-license mapping. An OpManager server running on a cloud virtual machine is one installation under the EULA,[6] and monitored cloud instances with IP addresses count as devices like any other.[1]
Programs
- Annual Subscription License and Perpetual License. The FAQ names these two licence types: an annual payment model and a one-time purchase model.[2]
- AMS. OpManager charges 20% of the licence cost as AMS and publishes both the perpetual and AMS prices.[1] Upgrades to newer versions are free while AMS is current.[2] After a version’s end of support (EOS) date, its users cannot renew AMS or get technical support, although they may keep running the build at their own risk until end of life. An AMS contract bought for an older version stays valid for its term, but the build must be updated before the EOS date.[5] Catalog proof: OpManager AMS is 20% of licence cost; upgrades are free with current AMS; AMS cannot be renewed for OpManager versions past end of support.
- OpManager IPF / ASF licence model. The Interface Polling Factor and Agent Support Factor model was adopted in July 2017. After the support period ends, the annual support fee must be paid for OpManager to keep working. Alerts start 60 days before expiry. From 15 days before expiry, the product shows a pop-up at every login and sends a daily email, and failing to renew makes OpManager non-functional.[3] Catalog proof: Under the IPF / ASF model OpManager stops functioning if the annual support fee is not paid.
- OpManager Nexus bundled licensing. The shared Device pack described above.[4]
- Evaluation License. The 30-day OpManager trial has all functions and no device limit. Longer evaluations need an extension licence.[2]
- Services. The store lists onsite assistance and online training as separately priced services.[7]
Out of scope
- OpManager MSP and the cloud-hosted probe service, which have their own terms.
- Standalone licences for NetFlow Analyzer, Network Configuration Manager, Firewall Analyzer, OpUtils and Applications Manager.
- Store prices, which the store page loads by script and which were not captured, and non-US currency prices.
