newrelic-mcp

name	newrelic-mcp
description	Use this skill whenever the user wants to query, debug, monitor, or analyze anything in New Relic — including logs, metrics, traces, APM data, alerts, incidents, dashboards, or infrastructure. Triggers on phrases like "check New Relic", "query NRQL", "look at alerts", "analyze performance", "what's happening in production", "check error rate", "find slow transactions", "investigate incident", or any request to pull observability or monitoring data. Also triggers when the user mentions APM, distributed tracing, golden signals, Errors Inbox, or synthetic monitors. Always use this skill rather than guessing — it contains the tool list, NRQL syntax, and multi-step workflows needed to do it right.

Decision: Which Tool First?

User asks about...
├── "what services do I have?" / "find X service"  →  get_entity
├── "any alerts / incidents / issues?"             →  list_recent_issues → search_incident
├── "how is X performing?"                         →  analyze_golden_metrics
├── "what errors are happening?"                   →  list_entity_error_groups → execute_nrql_query
├── "slow transactions"                            →  analyze_transactions
├── "check logs"                                   →  analyze_entity_logs / list_recent_logs
├── "did deploy cause this?"                       →  analyze_deployment_impact
└── anything else / complex                        →  natural_language_to_nrql_query

Common Workflows

Workflow 1: Production Error Investigation

1. get_entity           → find the service GUID
2. analyze_golden_metrics → health snapshot
3. list_entity_error_groups → error patterns
4. analyze_entity_logs  → log anomalies
5. list_change_events   → recent deployments
6. execute_nrql_query   → drill into specific errors

NRQL for step 6:

SELECT count(*), error.class, error.message
FROM TransactionError
WHERE entity.guid = '<guid>'
FACET error.class, error.message
SINCE 1 hour ago
LIMIT 20

---

Workflow 2: Performance Degradation

1. get_entity              → find the service GUID
2. analyze_transactions    → slow/error-prone endpoints
3. analyze_golden_metrics  → latency trend
4. list_garbage_collection_metrics → JVM health (if Java)
5. analyze_threads         → thread contention
6. analyze_deployment_impact → correlate with a deploy

---

Workflow 3: Alert Investigation

1. list_recent_issues             → open issues
2. generate_alert_insights_report → root cause analysis
3. generate_user_impact_report    → customer blast radius
4. get_entity                     → affected service
5. list_related_entities          → upstream/downstream impact
6. analyze_entity_logs            → logs during alert window
7. list_change_events             → correlated changes

---

Workflow 4: Natural Language (Quickest Path)

When the user's request is clear but the right NRQL isn't obvious, use:

natural_language_to_nrql_query(request="<user's question verbatim>")

This generates + executes NRQL automatically. Best for one-off queries.

NRQL Quick Reference

Structure

SELECT <functions/attributes>
FROM <event_type>
WHERE <filters>
FACET <grouping>
SINCE <time>
LIMIT <n>
TIMESERIES AUTO   -- optional, for trend charts

Key Event Types

• Transaction — APM spans
• TransactionError — app errors
• Span — distributed trace spans
• Log — log events
• Metric — dimensional metrics
• SystemSample — host infrastructure
• ProcessSample — process metrics

Golden Signal Queries

Latency (p95/p99):

SELECT percentile(duration, 95, 99) FROM Transaction SINCE 1 hour ago TIMESERIES AUTO

Error rate:

SELECT percentage(count(*), WHERE error IS true) FROM Transaction SINCE 1 hour ago

Throughput:

SELECT rate(count(*), 1 minute) FROM Transaction TIMESERIES AUTO SINCE 1 hour ago

Saturation:

SELECT average(cpuPercent), average(memoryUsedPercent) FROM SystemSample SINCE 1 hour ago

Time Ranges

• SINCE 30 minutes ago
• SINCE 1 hour ago UNTIL 5 minutes ago
• SINCE '2024-03-01 00:00:00'
• SINCE today

---

NRQL Rules (Always Follow)

✅ Do:

• Always include SINCE — be explicit even though default is 1 hour
• Use LIMIT to cap results
• Use FACET to group by service/error/host
• Use percentile() not average() for latency (p95/p99 is what matters)
• Filter by appName, service.name, or entity.guid to scope to one service
• Use TIMESERIES AUTO when you want to show a trend

❌ Don't:

• SELECT * without LIMIT (can return huge data)
• Query without any WHERE clause across a whole account
• Use long time ranges with raw event queries (use aggregations instead)
• Use vague LIKE '%..%' patterns on high-cardinality fields

---

Troubleshooting

Problem	Likely Cause	Fix
No results	Filters too strict or wrong event type	Widen time range, remove a WHERE clause, check attribute name casing
Query timeout	Too complex / time range too large	Add WHERE filters, narrow SINCE, reduce FACET cardinality
Missing attribute	Not instrumented or wrong name	Use Data Explorer in NR UI to check available attributes
Incomplete traces	Distributed tracing not enabled	Verify tracing config + context propagation across services
