name: onboarding-summary description: Generate a live Single Step Instrumentation (SSI) onboarding confirmation report for Linux hosts — verifies APM instrumentation is working end-to-end with deep links into the Datadog UI. Only use after agent-install and enable-ssi have both completed. metadata: version: "1.0.0" author: datadog-labs repository: https://github.com/datadog-labs/agent-skills tags: datadog,apm,linux,ssi,summary,verification alwaysApply: "false"

APM Onboarding Summary — Linux Host

Triggers

Invoke this skill when:

• All steps in verify-ssi have passed
• All checks in troubleshoot-ssi have been resolved
• The user asks "is everything working?", "show me the status", or "confirm APM is set up"

Do NOT invoke this skill if any verification or troubleshooting check is still failing — resolve those first.

---

Context to resolve before acting

Variable	How to resolve
HOSTNAME	hostname -f on the target host
DD_HOSTNAME	Hostname as Datadog sees it — from sudo datadog-agent status
SERVICE_NAME	DD_SERVICE value from /proc/<PID>/environ or the systemd unit
ENV	DD_ENV value from /proc/<PID>/environ or the systemd unit
DD_SITE	grep "^site:" /etc/datadog-agent/datadog.yaml
SSH_KEY	Path to SSH private key
SSH_USER	SSH username
SSH_HOST	Hostname or IP of the target host

---

Prerequisites

Claude runs

pup auth status --site <DD_SITE>

If valid token — proceed.

ERROR: Not authenticated:

Claude runs

pup auth login --site <DD_SITE>

This opens a browser tab for OAuth. Complete the login there — Claude will continue once the command exits.

---

Collect live confirmation data

Run all of the following. Each populates a row in the final report.

Claude runs

# Agent version and status
sudo datadog-agent status 2>&1 | grep -E "Agent \(v|Status:|API Keys status"

# Inject library armed in ld.so.preload
ssh -o StrictHostKeyChecking=no -i <SSH_KEY> <SSH_USER>@<SSH_HOST> "cat /etc/ld.so.preload"

# Process confirmed injected — launcher + language library in /proc/<PID>/maps
ssh -o StrictHostKeyChecking=no -i <SSH_KEY> <SSH_USER>@<SSH_HOST> \
  "pgrep -a -f '<SERVICE_NAME>' | head -3"

Use the PID from above:

ssh -o StrictHostKeyChecking=no -i <SSH_KEY> <SSH_USER>@<SSH_HOST> \
  "sudo cat /proc/<PID>/maps | grep -E 'launcher|apm-library|datadog'"

# UST vars in process environment
ssh -o StrictHostKeyChecking=no -i <SSH_KEY> <SSH_USER>@<SSH_HOST> \
  "sudo cat /proc/<PID>/environ | tr '\0' '\n' | grep -E 'DD_SERVICE|DD_ENV|DD_VERSION'"

# Agent APM receiver — trace counts
ssh -o StrictHostKeyChecking=no -i <SSH_KEY> <SSH_USER>@<SSH_HOST> \
  "sudo datadog-agent status 2>&1 | grep -A 10 'Receiver (previous minute)'"

# Service visible and traced in APM backend
DD_SITE=<DD_SITE> pup apm services list --env <ENV> --from 1h

# Traces arriving in the last hour
DD_SITE=<DD_SITE> pup traces search --query "service:<SERVICE_NAME>" --from 1h --limit 5

Only if DSM was enabled via enable-dsm:

# DSM pipeline data for the service
DD_SITE=<DD_SITE> pup metrics query \
  --query "avg:data_streams.latency{service:<SERVICE_NAME>,env:<ENV>} by {pathway_type}" \
  --from 15m --to now

---

Present the report

Fill in every value from live command output. Do not leave any placeholder unfilled. If a value cannot be confirmed, mark that row as failed and link to troubleshoot-ssi.

Security constraints

• Never write a raw API key into any file or chat message
