Gamma Incident Runbook

Overview

Systematic procedures for responding to and resolving Gamma integration incidents.

Prerequisites

• Access to monitoring dashboards
• Access to application logs
• On-call responsibilities defined
• Communication channels established

Incident Severity Levels

Quick Diagnostics

Step 1: Check Gamma Status

set -euo pipefail
# Check Gamma status page
curl -s https://status.gamma.app/api/v2/status.json | jq '.status'

# Check our integration health
curl -s https://your-app.com/health/gamma | jq '.'

# Quick connectivity test
curl -w "\nTime: %{time_total}s\n" \
  -H "Authorization: Bearer $GAMMA_API_KEY" \
  https://api.gamma.app/v1/ping

Step 2: Review Key Metrics

set -euo pipefail
# Check error rate (Prometheus)
curl -s 'http://prometheus:9090/api/v1/query?query=rate(gamma_requests_total{status=~"5.."}[5m])' | jq '.data.result'  # 9090: Prometheus port

# Check latency P95
curl -s 'http://prometheus:9090/api/v1/query?query=histogram_quantile(0.95,rate(gamma_request_duration_seconds_bucket[5m]))' | jq '.data.result'  # Prometheus port

# Check rate limit
curl -s 'http://prometheus:9090/api/v1/query?query=gamma_rate_limit_remaining' | jq '.data.result'  # Prometheus port

Step 3: Review Recent Logs

# Last 100 error logs
grep -i "gamma.*error" /var/log/app/gamma-*.log | tail -100

# Rate limit hits
grep "429" /var/log/app/gamma-*.log | wc -l  # HTTP 429 Too Many Requests

# Timeout errors
grep -i "timeout" /var/log/app/gamma-*.log | tail -50

Incident Response Procedures

Scenario 1: API Returning 5xx Errors

Symptoms:

• High error rate in monitoring
• Users reporting failed presentations
• 500/502/503 responses from Gamma

Actions:

1. Verify Gamma status: https://status.gamma.app
2. If Gamma outage confirmed:

- Enable degraded mode / show maintenance message - Monitor status page for updates - No action needed on our side

1. If Gamma is operational: # Check our request patterns grep "5[0-9][0-9]" /var/log/app/gamma-*.log | \ awk '{print $1}' | sort | uniq -c | sort -rn # Look for malformed requests grep -B5 "500" /var/log/app/gamma-*.log | grep "request"
2. Rollback recent deployments if issue correlates

Scenario 2: Rate Limit Exceeded (429)

Symptoms:

• 429 responses in logs
• Rate limit metrics at zero
• Slow or queued requests

Actions:

1. Immediate mitigation: # Enable request throttling curl -X POST http://localhost:8080/admin/throttle \ -d '{"gamma": {"rps": 10}}'
2. Check for runaway processes: # Find high-volume clients grep "gamma" /var/log/app/*.log | \ awk '{print $5}' | sort | uniq -c | sort -rn | head -20
3. Enable circuit breaker: curl -X POST http://localhost:8080/admin/circuit-breaker \ -d '{"service": "gamma", "state": "open"}'
4. Long-term: Review rate limit tier with Gamma

Scenario 3: High Latency

Symptoms:

• Slow presentation creation
• Timeouts in logs
• P95 latency > 10s

Actions:

1. Check Gamma latency vs our latency: # Direct Gamma latency for i in {1..5}; do curl -w "%{time_total}\n" -o /dev/null -s \ -H "Authorization: Bearer $GAMMA_API_KEY" \ https://api.gamma.app/v1/ping done
2. If Gamma is slow:

- Increase timeouts temporarily - Enable async mode for non-critical operations - Queue heavy operations

1. If our infrastructure is slow:

- Check CPU/memory on app servers - Review connection pool settings - Check network connectivity

Scenario 4: Authentication Failures (401/403)

Symptoms:

• All requests failing with 401
• "Invalid API key" errors
• Sudden authentication failures

Actions:

1. Verify API key: # Test key directly curl -H "Authorization: Bearer $GAMMA_API_KEY" \ https://api.gamma.app/v1/ping # Check key format echo $GAMMA_API_KEY | head -c 20
2. If key is invalid:

- Check if key was rotated - Deploy backup key: GAMMA_API_KEY_SECONDARY - Generate new key in Gamma dashboard

1. Notify team and update secrets

Next Steps

Proceed to gamma-data-handling for data management.

Instructions

1. Assess the current state of the Gamma configuration
2. Identify the specific requirements and constraints
3. Apply the recommended patterns from this skill
4. Validate the changes against expected behavior
5. Document the configuration for team reference
