Add comprehensive SigNoz configuration guide and monitoring setup
Documentation includes:
1. OpAMP Root Cause Analysis:
- Explains OpenAMP (Open Agent Management Protocol) functionality
- Documents how OpAMP was overwriting config with "nop" receivers
- Provides two solution paths:
* Option 1: Disable OpAMP (current solution)
* Option 2: Fix OpAMP server configuration (recommended for prod)
- References: SigNoz architecture and OTel collector docs
2. Database Receivers Configuration:
- PostgreSQL: Complete setup for 21 database instances
* SQL commands to create monitoring users
* Proper pg_monitor role permissions
* Environment variable configuration
- Redis: Configuration with/without TLS
* Uses existing redis-secrets
* Optional TLS certificate generation
- RabbitMQ: Management API setup
* Uses existing rabbitmq-secrets
* Port 15672 management interface
3. Automation Script:
- create-pg-monitoring-users.sh
- Creates monitoring user in all 21 PostgreSQL databases
- Generates secure random password
- Verifies permissions
- Provides next-step commands
Resources Referenced:
- PostgreSQL: https://signoz.io/docs/integrations/postgresql/
- Redis: https://signoz.io/blog/redis-opentelemetry/
- RabbitMQ: https://signoz.io/blog/opentelemetry-rabbitmq-metrics-monitoring/
- OpAMP: https://signoz.io/docs/operate/configuration/
- OTel Config: https://signoz.io/docs/opentelemetry-collection-agents/opentelemetry-collector/configuration/
Current Infrastructure Discovered:
- 21 PostgreSQL databases (all services have dedicated DBs)
- 1 Redis instance (password in redis-secrets)
- 1 RabbitMQ instance (credentials in rabbitmq-secrets)
Next Implementation Steps:
1. Run create-pg-monitoring-users.sh script
2. Create Kubernetes secrets for monitoring credentials
3. Update signoz-values-dev.yaml with receivers
4. Enable receivers in metrics pipeline
5. Test and verify metric collection
