Searching for Datadog alternatives?

ManageEngine OpManager Nexus is a cost-effective, AI-driven observability alternative to Datadog!

Full-stack observability meets enterprise-grade security intelligence

Overview

OpManager Nexus is a simple, cost-effective alternative to Datadog. Datadog's billing for hosts, data intake, and searches can run you into overages without active financial oversight. With OpManager Nexus, you don't have to spend more than your allocated observability budget. You get fixed, upfront pricing based on your monitored resources. Clear caps on your usage ensure that you get no surprises with your bills, only deep infrastructure visibility and smart AI tools for one clear price, with savings up to 90%.

Get started

Simple, transparent, and fixed billing

  • Datadog follows a usage-based pricing model that charges you for: the number of hosts or instances you're monitoring, the amount of data you ingest, and indexed data. This often results in a situation where you have pay twice or thrice for monitoring the same system.
  • With OpManager Nexus, the pricing is predictable and completely within your control. You can monitor a certain number of resources, with fixed billing and flat-rates for cloud costs.
  • OpManager Nexus' flexible deployment strategy also helps you control your spending. The self-hosted version allows you to structure your costs up-front. While the SaaS version allows you to get started with minimal infrastructure costs.
Your network has a normal. Security Analytics knows when it isn't.

Cost-effective OpenTelemetry portability

  • Datadog bills OpenTelemetry (OTel) and custom metrics per host/microservice. This often leads to large bills and overages for complex microservice deployments.
  • OpManager Nexus offers a cost-effective alternative to Datadog when it comes to OTel. The on-premises model is billed based on the number of hosts.You can monitor unlimited OTel metrics for each host or microservice.
  • The cloud model of OpManager Nexus uses a flat GB rate for OTel. You can monitor any number of hosts or microservices you want within a fixed data volume. If your OTel metrics increase beyond that fixed volume, you can extend it with add-ons.

AI built in as a platform, not an add-on

OpManager Nexus delivers powerful AI and ML features while giving you the flexibility to choose the AI that works best for you.

  • Built-in AI assistance: OpManager Nexus has Zoho's Zia AI built into its interface. You can run Zia as an autonomous agent (in the cloud model), or as an on-demand analytics assistant.
  • GenAI integrations: OpManager Nexus integrates with GenAI LLMs to give you real-time IT insights. You can also integrate Ollama's local LLMs to enable secure, air-gapped AIOps.
  • Model context protocol (MCP) server: OpManager Nexus supports a native MCP server. You can connect it with AI assistants and LLMs through a natural language interface.
Every threat has a name. MITRE ATT&CK makes sure you know It.
When incidents happen, answers shouldn't be hard to find

Unparalleled network and infrastructure observability

OpManager Nexus leads the market in network and infrastructure observability with some key features.

  • Native gNMI (gRPC network management) support: OpManager Nexus supports gNMI's push-based telemetry. gNMI allows network devices to stream telemetry on a sub-second level. Without gNMI, anomalies, traffic spikes, and hardware telemetry cannot be captured in real-time to provide true network observability.
  • Network config management: Datadog supports viewing and tracking changes to network configs. But unlike OpManager Nexus, it cannot perform rollbacks or push config changes in bulk. In the event of an outage, OpManager Nexus lets you detect issues, and backup an operational config in seconds.
  • DNS, DHCP, and IP management: OpManage Nexus also helps you resolve DNS, DHCP, and IP service issues, giving you complete end-to-end control over your infrastructure.

Full-stack observability, from switch-ports to app-stacks

Datadog requires you to look at three separate maps from two different modules to visualize your full-stack infrastructure. A separate map for apps and services, one for network topology, and one for VMs and containers.

OpManager Nexus has a unified organization map that automatically draws your infrastructure: from switch-port to applications.

  • This helps you translate infrastructure-level faults to app, service, and user-experience issues in a single glance.
  • You can see the servers, VMs, containers, and databases hosting your business services to perform impact analysis and optimization.
  • When user-facing services go down, you can correlate issues across stacks to speed up root-cause analysis.
Enterprise-scale protection. Zero additional infrastructure.

Pricing comparison: OpManager Nexus vs Datadog

How much do you save by moving from Datadog to OpManager Nexus?

Datadog has a complex license plan that charges you per host per month. You cannot purchase Datadog APM by itself. You must also pay for the underlying Infrastructure license ($15 to $23 per host), making the baseline entry cost roughly $46 to $58 per host, per month. On top of this, Datadog has usage based costs for ingestion and indexing. Accidental usage spikes could easily run you into overages.

OpManager Nexus, on the other hand has a simple, element based license. Even excluding Datadog's usage-based costs, OpManager Nexus can be up to 90% cheaper.

FAQ

Why do teams look for an alternative to Datadog?

Datadog's pricing penalizes teams with per-host billing, expensive custom metrics, cardinality-based surcharges, and a dual-cost log management where you pay once to ingest and again to index. Datadog’s pricing is designed to increase spend without active billing governance.

Many teams also shift from Datadog because of vendor lock-in. To use Datadog, you must embed their agent throughout your infrastructure. They also penalize the usage of open standards like OTel with custom metric billing.

Datadog competitors like OpManager Nexus, Dynatrace, Grafana, New Relic, and SigNoz offer different kinds of solutions for these problems.

What are the benefits of a self-hosted Datadog alternative?

For teams under GDPR, HIPAA, or FedRAMP, Datadog has no self-hosted option. All telemetry flows through Datadog's managed infrastructure, which is an obstacle for teams subject to data residency policies. Self-hosted solutions give you complete control over telemetry.

How does OpManager Nexus compare with Dynatrace?

Dynatrace is similar to Datadog with a complex, usage-based pricing model. OpManager Nexus offers several benefits compared to Dynatrace:

  • OpManager Nexus has a simple and predictable pricing model.
  • You get complete infrastructure coverage, from the network to the app stack.
  • You can deploy it on-premises or on the cloud.
  • You can monitor distributed hybrid environments with ease.
Will switching away from Datadog cause vendor lock-in problems?

Teams switching from Datadog can often face vendor lock-in issues. If you decide to switch, you face a major migration project ripping out the Datadog agent and re-instrumenting your app stack.

OpenTelemetry (OTel) is the key to avoiding vendor lock-in. OpManager Nexus supports OTel natively. Moreover, you also get a dedicated team to help you migrate from Datadog to OpManager Nexus with ManageEngine's enterprise support.

How does gNMI push-based telemetry differ from standard pull-based monitoring?

Traditional monitoring tools pull device data at fixed intervals (typically every 1 to 5 minutes). This creates visibility gaps during short-lived traffic spikes or hardware errors. OpManager Nexus addresses this by providing native support for gNMI push-based telemetry. Instead of waiting for a request, network devices stream telemetry data continuously.
