OpenTelemetry Collector Fleet Management, Governed by Default.
Deploy, govern, and cost-optimize your entire collector fleet — with a built-in Copilot that answers from your live data and does the legwork, while your engineers approve every action. Neutral to any backend, audited end to end, free to use, self-hosted on your infrastructure.
✓ Fleet is stable. All agents running policy v1.4.1.
Why Collector Fleets Break Without a Control Plane
SSH into 50 servers to change one config
Manual config edits across hundreds of nodes are slow, error-prone, and impossible to audit.
Restarting collectors = telemetry gaps
Every collector restart tears down network sockets and drops data. Users notice.
No idea if your fleet is healthy
Collectors fail silently. By the time you notice missing data, the incident is already live.
Built for Engineers Who Need Fleet Control
Managing OpenTelemetry Collectors across hundreds of servers, Kubernetes clusters, and Windows machines is painful. CollectorCtrl replaces SSH scripts and manual config edits with a centralized, policy-driven control plane — every change authenticated, authorized, and written to an audit trail.

Meet the CollectorCtrl Copilot
Stop hunting through pages, filters, and YAML. Just ask. The Copilot lives on every page, answers with your live fleet data, shows its work — and never applies a change without your approval.
- Evidence, not vibesEvery answer ships with an Agent Reasoning trace of the exact tools consulted.
- It proposes, you approveInline approval cards with blast radius and full diff — right in the chat.
- Clickable answersCollectors, templates, and packages become chips that take you straight there.
- Diagrams rendered in chatInteractive pipeline topology with a one-click source view, in every theme.
- Apply to EditorSuggested YAML lands in the collector's config editor in one click.
- It remembersPage-aware prompts, "this"-aware context, and chat history that survives refresh.
otel-prod-07 went unhealthy 12 min ago. The config pushed at 14:02 points its exporter at an endpoint that now fails the TLS handshake. Rolling back restores the last known-good config.
Who Uses CollectorCtrl
Platform & SRE Teams
Manage OTel Collectors across dev, staging, and production from one dashboard. Roll out config changes to specific environment rings. Detect unhealthy agents before they impact telemetry pipelines.
Security & Compliance
Stream every action to your SIEM via OTLP. Audit who changed what config and when. Enforce RBAC with SSO group mapping.
Multi-Cloud Observability
Run the server on-prem or in your VPC. Agents connect outbound — no inbound firewall rules needed. Works across AWS, Azure, GCP, and private data centers.
Pipeline & Cost Governance
The control plane is where the observability bill is decided. Build custom OTel Collector binaries with the integrated OCB Builder, filter and sample before data reaches expensive backends, and deploy the right version to the right machine with fleet policies.
If You Don't Own the Control Plane, You're Not Vendor-Neutral
Vendor leverage in OpenTelemetry is real, support tiers are rational, and your exit strategy lives in one layer most teams never audit. An honest scorecard of the four architectures everyone proposes — no pitch at the end.
