Your telemetry
has a new user.

Agents. Tero continuously understands the telemetry across the stores you already use, finds cost, compliance, and reliability issues, and proves every finding with raw evidence.

See Tero on your dataRead the docs
  • Connect read-only. Nothing to deploy.
  • First findings in 10–15 minutes.
  • Find 40–60% waste.
  • Every finding backed by raw evidence.

The agent-native
telemetry layer.

One read-only layer over the stores you already use. No migration, no pipelines. Connect and Tero builds the index and surfaces issues in minutes.

01

Tero Index

Turns raw telemetry into maintained context.

02

Tero Issues

Finds problems before they become fire drills.

03

Tero Actions

Safe paths to production change.

04

Tero Query

Opens the same context to agents.

01 · TERO INDEX

Tero Index turns raw telemetry into maintained context.

Raw records become event types, changes, ownership, facts, and evidence, maintained continuously across the stores you already use.

Events, not records

Repetitive telemetry grouped into meaningful event types.

Filter by meaning

Change, domain, outcome, impact, signal.

Watch change over time

New, spiking, missing, or changed events.

Drill into evidence

Facts, examples, trends, owners, raw records.

02 · TERO ISSUES

Tero Issues finds problems before they become fire drills.

Cost waste. Sensitive data. Compliance exposure. Reliability risk. Raised with evidence, owner, impact, and next step.Explore the live demo

Cut waste before renewal

High-volume, low-value events, debug noise, oversized payloads. Data you ingest only to drop later.

Catch sensitive data at the source

PII, PHI, payment data, secrets, and tokens, surfaced with examples, owners, and destinations.

See reliability risk while it is still quiet

Recurring failures, terminal errors, dependency issues, and slow degradation already visible in the logs.

03 · TERO ACTIONS

Tero Actions gives agents safe paths to production change.

Issues should not end as reports. Tero routes each issue to the owner, workflow, policy, or agent that can act. Routine telemetry cleanup can move automatically; complex work keeps the evidence attached.

04 · TERO QUERY

Tero Query opens the same context to agents.

Agents can inspect issues, ask what changed, and pull raw records through one MCP over connected stores. Raw records stay the source of truth; Tero gets agents to the right records after the index narrows the work.

One interface over every store.

Datadog, ClickHouse, S3, CloudWatch, Elastic, R2, GCP Logging, and whatever comes next.

Start from context, not syntax.

Agents ask about services, domains, outcomes, changes, issues, and evidence instead of guessing schemas and query language.

Pull raw records with purpose.

Raw telemetry stays the source of truth. Tero gets agents to the right event, time range, examples, and source links first.
