Review Summary:

This PR adds two Grafana monitoring dashboards and improves a .gitignore pattern. The changes look good overall with no critical issues identified.

Changes Reviewed:

1. Grafana Dashboards (4,759 additions)

   • teranode-batch-index-dashboard.json - Monitors Aerospike batch index performance with 7 panels tracking queue depth, delays, memory allocation, buffer consumption, throughput, and payload size
   • teranode-overview-dashboard.json - Comprehensive teranode metrics dashboard with transaction processing, service health, and system-level monitoring
   • Both dashboards follow existing patterns in deploy/docker/base/grafana_dashboards/

2. .gitignore Update (1 line changed)

   • Changed teranode → /teranode to make the ignore pattern more specific to the root directory only
   • This prevents accidentally ignoring any directory/file named "teranode" in subdirectories
   • This is a good defensive change

Observations:

• Dashboard JSON files are configuration-as-code, standard for Grafana deployments
• Panel descriptions include helpful "What Good Looks Like" guidance for operators
• Metrics align with existing Prometheus/Aerospike instrumentation
• No code execution risk - purely declarative JSON configuration

Recommendation: Approve - These monitoring improvements will help operators diagnose performance issues in production deployments.
