The intelligence layer for telemetry

Find what's hidingin your telemetry.

Tero connects read-only to your observability stack and finds costly waste, compliance risk, and production problems your current tools miss. Every finding includes raw evidence, measured impact, and a safe path to resolution.

  • Keep your existing stack.
  • Nothing to deploy or re-pipeline.
  • Every finding backed by raw evidence.

How Tero works

One intelligence layer
over every telemetry store.

Your existing tools store and query telemetry. Tero continuously understands what is inside them, finds important issues, and gives each one a path to resolution.

01

Tero Index

Understands and maintains telemetry context.

02

Tero Issues

Detects, investigates, and proves real problems.

03

Tero Actions

Provides controlled ways to resolve them.

04

Tero Query

Gives agents one place to query telemetry with context.

01 · TERO INDEX

Your telemetry, understood and kept current.

Tero Index turns raw telemetry and the context around it into a living model of production. It combines deterministic analysis with AI to group billions of records into meaningful events, connect behavior across services and signals, fill in missing context, and keep every conclusion 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

Important problems, investigated before they become fire drills.

Tero continuously looks for costly waste, sensitive data, and production risks before they become urgent. Every issue arrives investigated with scope, impact, ownership, raw 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

Give every issue a safe path to production change.

Apply focused, reviewable, reversible Telemetry Policies in real time without rewriting or redeploying shared pipeline configuration. Hand engineering work to agents with the investigation, ownership, and raw evidence already attached.

Hand issues directly to coding agents.

Send the completed investigation, affected service, ownership, evidence, and links to raw records.

TELEMETRY GOVERNANCE

Let teams own their telemetry.

Route evidence-backed issues to the responsible teams through the workflows they already use.

04 · TERO QUERY

Give every agent the context Tero uses.

Tero Query lets agents investigate and close issues using the same context Tero used to find them. They start from the Index, then query connected stores and drill into raw evidence when needed.
