📊 Performance Monitoring & Health Dashboard in ServiceNow

🌐 Introduction

As ServiceNow instances grow with data, customizations, and integrations, performance and health monitoring becomes critical.

• Performance Monitoring tracks system speed, memory, transaction logs, and response times.

• Health Dashboard provides a visual, consolidated view of instance health across performance, configuration, and error metrics.

💡 Key Benefit: Together, they ensure the platform remains stable, scalable, and optimized while reducing risks of downtime.

📑 Performance Monitoring in ServiceNow

🔹 What it Does

• Tracks performance metrics like:

  • Average response times.

  • Database query times.

  • Slow-running transactions.

  • Node availability in multi-node clusters.

🔹 Tools Available

1. Performance Analytics (PA):

   • Custom KPIs for application or process performance.

2. System Logs:

   • Identify slow queries, script execution issues, or memory leaks.

3. Transaction Log:

   • Details execution time for each user transaction.

4. Instance Performance Dashboard:

   • OOTB dashboard showing instance speed, node status, memory usage.

📑 Health Dashboard

🔹 Purpose

The Health Dashboard gives administrators a high-level overview of the platform’s technical health.

🔹 Key Health Indicators

• Database Growth – Monitors large tables and storage usage.

• Error Logs – Identifies recurring system/application errors.

• Integration Errors – Tracks failed REST/SOAP calls.

• Upgrade Readiness – Highlights skipped/modified OOTB objects.

• Security Posture – Reports open vulnerabilities and weak configurations.

🔹 Modules

1. Instance Health:

   • Shows status of jobs, errors, and performance KPIs.

2. System Diagnostics:

   • Tools like stats.do and node_stats.do for live node performance.

3. Application Health Dashboard:

   • Checks technical debt (unscoped apps, outdated scripts, unused fields).

4. Security Health Dashboard:

   • Ensures access controls, certificates, and encryption are valid.

⚡ Advanced Features

• Event Management Integration:

  • Combine instance events with ITOM for proactive alerts.

• Health Scan (with ServiceNow Support):

  • Automated deep analysis of configurations, customizations, and performance risks.

• Predictive Intelligence Add-on:

  • Detects anomaly patterns in performance trends.

• Proactive Monitoring:

  • Alerts via email, Slack, or MS Teams when thresholds are breached.

🛠️ Real-World Examples

1. Global Bank

   • Uses Health Dashboard to monitor transaction volume spikes during quarter-end.

   • Proactively adds server nodes before peak load.

2. Healthcare Provider

   • Monitors large CMDB growth to ensure compliance with HIPAA storage requirements.

3. Retail Company

   • Uses monitoring to detect failed vendor API calls.

   • Prevents delays in e-commerce order processing.

📊 Benefits

• Improved Uptime – Early detection prevents outages.

• Scalability – Helps plan infrastructure growth.

• Audit Readiness – Health metrics aid compliance checks.

• Reduced MTTR – Faster issue detection → quicker fixes.

• Optimization – Identify bottlenecks and unnecessary customizations.

💡 Best Practices

• ✅ Regularly review performance dashboards (daily/weekly).

• ✅ Use threshold alerts for critical metrics.

• ✅ Run Instance Health Scans before upgrades.

• ✅ Archive old records to improve database performance.

• ✅ Optimize scripts and queries flagged as slow.

• ❌ Don’t ignore recurring minor errors—they usually indicate larger issues.

• ❌ Avoid running heavy scheduled jobs during business peak hours.
