Datadog APM

Distributed tracing, service maps, and performance analysis.

Requirements

Datadog Labs Pup should be installed. See Setup Pup if not.

Command Execution Order (Token-Efficient)

For scoped commands, use this order:

1. Check context first (prior outputs, conversation, saved values).
2. If a required value is missing, run a discovery command first.
3. If still ambiguous, ask the user to confirm.
4. Then run the target command.
5. Avoid speculative commands likely to fail.

Quick Start

pup auth login
# Confirm env tag with the user first (do not assume production/prod/prd).
pup apm services list --env <env> --from 1h --to now
pup traces search --query "service:api-gateway" --from 1h

Services

List Services

pup apm services list --env <env> --from 1h --to now
pup apm services stats --env <env> --from 1h --to now

Service Stats

pup apm services stats --env <env> --from 1h --to now

Service Map

# View dependencies
pup apm flow-map --query "service:api-gateway&from=$(($(date +%s)-3600))000&to=$(date +%s)000" --env <env> --limit 10

Traces

Search Traces

# By service
pup traces search --query "service:api-gateway" --from 1h

# Errors only
pup traces search --query "service:api-gateway status:error" --from 1h

# Slow traces (>1s)
pup traces search --query "service:api-gateway @duration:>1000ms" --from 1h

# With specific tag
pup traces search --query "service:api-gateway @http.url:/api/users" --from 1h

Trace Detail

# No direct get command for a single trace ID.
# Use traces search with a narrow query and time window.
pup traces search --query "trace_id:<trace_id>" --from 1h

Key Metrics

Metric	What It Measures
trace.http.request.hits	Request count
trace.http.request.duration	Latency
trace.http.request.errors	Error count
trace.http.request.apdex	User satisfaction

Service Level Objectives

Link APM to SLOs:

pup slos create --file slo.json

Common Queries

Goal	Query
Slowest endpoints	avg:trace.http.request.duration{*} by {resource_name}
Error rate	sum:trace.http.request.errors{*} / sum:trace.http.request.hits{*}
Throughput	sum:trace.http.request.hits{*}.as_rate()

Troubleshooting

Problem	Fix
No traces	Check ddtrace installed, DD_TRACE_ENABLED=true
Missing service	Verify DD_SERVICE env var
Traces not linked	Check trace headers propagated
High cardinality	Don't tag with user_id/request_id
