| Deployment | The FusionReactor agent is available on-premise or can be added to Cloud, and the maker says data can stay local. | Metoro is installed with Helm and is available as Metoro Cloud, BYOC, or on-premises deployment. |
| OpenTelemetry | The Q2 2026 product update says the agent can export Java and ColdFusion telemetry to OpenTelemetry-compatible backends including Datadog, New Relic, Grafana Cloud, Honeycomb, and Splunk. | The in-cluster exporter accepts custom metrics through an OTLP HTTP endpoint and examples are provided for Python, Go and Node.js. |
| Purpose | FusionReactor APM monitors application performance and helps identify why applications perform poorly or break. | Metoro continuously profiles Kubernetes workloads using an eBPF sampling profiler running at the kernel level. |
| Security | The security page states Intergral Information Systems GmbH is SOC 2 Type 2 compliant and that personal data processing is GDPR compliant. | Metoro states SOC 2 Type II certification, TLS 1.3 in transit, AES-256 at rest, SSO/SAML, RBAC and audit logging for Cloud. |
| Support | The site provides a Contact Support page for requesting assistance. | The Scale plan includes support via Slack with Metoro engineers, while Enterprise includes 24/7 white-glove support and onboarding. |
| Supported runtimes | The FusionReactor agent is available for monitoring Java and ColdFusion applications. | The profiling page lists Go, Python, C++, C, Rust, Node.js and Java, plus additional runtimes, with no language agent required. |

Metoro Kubernetes Profiling
Metoro Kubernetes Profiling continuously profiles Kubernetes workloads with an eBPF sampler running at the kernel level. It creates interactive flame graphs that can be grouped by service, pod, or container and filtered by cluster, namespace, deployment, or Kubernetes label. Metoro lists Go, Python, C++, C, Rust, Node.js, and Java support, with host-level frames for other runtimes. Profiling does not require SDKs, code changes, language agents, restarts, or rebuilds, and can cover third-party containers and vendor workloads. Profiles connect to Metoro APM traces, logs, metrics, pod state, and deployment context. Installation uses Helm, with Cloud, BYOC, and on-premises deployment options. The free Hobby plan includes one cluster, one user, and two nodes with 28-day retention. Scale costs $20 USD per node per month, plus $0.20 per GB above 100GB per node. Enterprise pricing is contract-based and offers custom retention and SLAs. eBPF requires Linux kernel 4.18 or newer.
