What is Monoscope?

Monoscope is an open-source observability platform that stores your telemetry data in S3-compatible storage. Self-host it or use our cloud offering.

Core capabilities:

• 💰 S3 storage — Store years of logs, metrics, and traces affordably in your own S3 buckets
• 💬 Natural language queries — Search your data using plain English via LLMs
• 🤖 AI agents — Create agents that run on a schedule to detect anomalies and surface insights
• 📧 Email reports — Receive daily/weekly summaries of important events and anomalies
• 🔭 OpenTelemetry native — 750+ integrations out of the box
• ⚡ Live tail — Stream logs and traces in real-time
• 🕵️ Unified view — Correlate logs, metrics, traces, and session replays in one place

Cloud vs Self-hosted

In both options, you bring your own S3 buckets—your data stays yours.

	Cloud	Self-hosted
Storage	Your S3 buckets	Your S3 buckets
Compute	Managed by us	You manage
Auth & SSO	Built-in	DIY
Alert channels	Slack, PagerDuty, etc.	Basic email
Pricing	Usage-based	Free (AGPL-3.0)

→ Start free on Cloud or continue below to self-host.

The Cloud Free plan supports one user: the project owner (the first member added when the project is created). Other members can access the project after an upgrade. This limit does not apply to self-hosted Open Source projects.

Quick Start

git clone https://github.com/monoscope-tech/monoscope.git
cd monoscope
docker-compose up

Visit http://localhost:8080 (default: admin/changeme)

Send Test Data

Populate your dashboard with test telemetry:

monoscope auth login

# Single event — see your message appear in the dashboard
monoscope send-event -m "Hello from Monoscope"

# Sustained load — stress-test the pipeline
monoscope telemetrygen --kind=trace --rate=5 --count=50

CLI

Manage your Monoscope project from the terminal — search logs, query metrics, manage monitors and dashboards, triage issues, and more.

curl https://monoscopehq.com/install.sh | sh
monoscope auth login

See the CLI reference for the full command list.

Agentic pipeline

Every CLI command emits a stable JSON envelope, so you can chain discovery → search → triage without manual munging. This is the same pipeline a Claude Code skill runs end-to-end:

# 1. What services exist? (Precomputed; no aggregation query needed.)
SVC=$(monoscope facets resource.service.name --top 1 \
        | jq -r '.["resource.service.name"][0].value')

# 2. Grab one error event from that service — id only, ready to chain.
ID=$(monoscope logs search 'severity.severity_text=="error"' \
        --service "$SVC" --first --id-only)

# 3. Pull the surrounding 5 minutes of traffic, with a per-trace summary
#    showing which other services were affected.
monoscope events context --window 5m --summary \
  --at "$(monoscope events get "$ID" | jq -r .timestamp)" \
  | jq '.traces | sort_by(-.error_count) | .[0:3]'

# 4. Acknowledge the open issue once you have a hypothesis.
monoscope issues list --service "$SVC" --status open \
  | jq -r '.data[].id' | head -3 \
  | xargs -I {} monoscope issues ack {}

Each step's output shape is documented and stable:

Command	Envelope
facets [FIELD]	{<field_path>: [{value, count}, ...]}
events search (and logs/traces)	{events: [...], count, has_more, cursor}
events context --summary	{events, count, traces: [{trace_id, services, span_count, error_count}]}
issues list, monitors list, ...	{data: [...], pagination: {has_more, total, cursor, page, per_page}}
auth status (agent mode)	{authenticated, method, api_url, project}

Set MONOSCOPE_AGENT_MODE=1 (or run with --agent) to force JSON output and disable interactive prompts — auto-detected when CI or CLAUDE_CODE is set.

Claude Code Skills

Let Claude investigate incidents, triage alerts, and write KQL queries using the monoscope CLI — install the skills plugin:

# Claude Code
claude plugin marketplace add monoscope-tech/skills
claude plugin install monoscope-skills@monoscope-skills

# or via npx (Cursor, Cline, Copilot, and other agents)
npx skills add monoscope-tech/skills

Restart Claude Code after installation. Skills activate automatically when relevant — e.g. "investigate the 500 errors in payment-api" or "do an on-call sweep".

See github.com/monoscope-tech/skills for the full skill list and documentation.

MCP Server

Monoscope exposes itself as a Model Context Protocol server at /api/v1/mcp, so any MCP-aware client (Claude Desktop, Cursor, Cline, custom agents) can search events, manage monitors and dashboards, triage issues, and run composite workflows like search_events_nl (natural-language → KQL) and analyze_issue (LLM-assisted root-cause).

{
  "mcpServers": {
    "monoscope": {
      "url": "https://api.monoscope.tech/api/v1/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Every public REST endpoint is auto-registered as a verb-first tool (list_monitors, search_events, mute_monitor, …). See the MCP reference for the full protocol, tool catalog, and examples.

Integration

Auto-instrument your apps

pip install opentelemetry-distro opentelemetry-exporter-otlp
opentelemetry-bootstrap -a install
OTEL_SERVICE_NAME="my-app" \
OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4317" \
opentelemetry-instrument python myapp.py

npm install --save @opentelemetry/auto-instrumentations-node
OTEL_SERVICE_NAME="my-app" \
OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4317" \
node --require @opentelemetry/auto-instrumentations-node/register app.js

curl -L https://github.com/open-telemetry/opentelemetry-java-instrumentation/releases/latest/download/opentelemetry-javaagent.jar -o otel-agent.jar
OTEL_SERVICE_NAME="my-app" \
OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4317" \
java -javaagent:otel-agent.jar -jar myapp.jar

# Install OpenTelemetry Operator
kubectl apply -f https://github.com/open-telemetry/opentelemetry-operator/releases/latest/download/opentelemetry-operator.yaml

# Configure auto-instrumentation
kubectl apply -f - <<EOF
apiVersion: opentelemetry.io/v1alpha1
kind: Instrumentation
metadata:
  name: my-instrumentation
spec:
  exporter:
    endpoint: http://monoscope:4317
  propagators:
    - tracecontext
    - baggage
EOF

# Annotate your deployments for auto-instrumentation
kubectl patch deployment my-app -p \
  '{"spec":{"template":{"metadata":{"annotations":{"instrumentation.opentelemetry.io/inject-java":"my-instrumentation"}}}}}'

Natural Language Queries

Query your telemetry data in plain English:

• "Show me all errors in the payment service in the last hour"
• "What caused the spike in response time yesterday?"
• "Which endpoints have the highest p99 latency?"

AI Agents & Reports

Create AI agents that monitor your systems on a schedule:

• Scheduled analysis — Agents run at intervals you define (hourly, daily, weekly)
• Anomaly detection — Automatically surface unusual patterns in logs, metrics, and traces
• Email reports — Receive summaries of important events and insights directly in your inbox
• Customizable focus — Configure agents to watch specific services, error types, or metrics
