Your telemetry haswork to do.

Tero connects read-only to the telemetry you already store and continuously finds costly waste, sensitive data, and operational risks your current tools miss. Every issue is backed by raw evidence and ready to trigger the agent or workflow you choose.

How Tero works

The agent-native telemetry layer.

01

Tero Index

Builds a living model of your telemetry.

02

Tero Issues

Finds and investigates material problems.

03

Tero Actions

Triggers safe paths to production change.

04

Tero Query

Gives agents the context to investigate and act.

01 · TERO INDEX

Turn messy telemetry into a living model of production.

Tero turns raw records into a continuously maintained understanding of what exists, what changed, and who owns it. Every conclusion stays linked to raw evidence.

See the whole system

Turn fragmented telemetry into one coherent picture of production.

Understand what it means

Purpose, behavior, relationships, ownership, and value.

See what changes

New, missing, growing, declining, and changing telemetry.

Inspect the evidence

Move from any conclusion to examples, trends, and raw records.

02 · TERO ISSUES

Find the issues your current tools miss.

Costly waste, sensitive data, and operational risk arrive already investigated, with impact, ownership, evidence, and a recommended next step.Explore the live demo

Telemetry waste

Duplicate, unused, over-retained, and high-volume telemetry delivering little or no value.

Sensitive data

Personal data, payment information, secrets, and tokens found with examples, sources, and owners.

Reliability risk

Retries, recurring failures, degraded dependencies, and quiet patterns that can become incidents.

03 · TERO ACTIONS

Trigger the right action for every issue.

Apply a safe Telemetry Policy, trigger the agent you choose, or route the issue into the workflow your team already uses.

EXISTING SYSTEMS

Route the investigation into the systems you already use.

Send completed issues into your existing orchestration workflows. Let the system decide whether an agent or person handles it.

04 · TERO QUERY

Give agents the context to finish the work.

Agents start with the issue and completed investigation, then query connected stores and drill into raw evidence when needed.

One place to query every store.

Work across Datadog, ClickHouse, object storage, and every connected system through one interface.

Start with prepared context.

Understand services, events, ownership, behavior, and change without rediscovering the estate.

Drill into raw evidence.

Follow context back to the records and systems of truth that support it.
