feat(helm): Add observability support with ServiceMonitor and Grafana dashboard
Add comprehensive observability configuration to Helm chart: **Helm Values:** - Add observability configuration section for metrics, tracing, and logging - Add serviceMonitor configuration (disabled by default) - Add prometheusRule configuration (disabled by default) **Templates:** - Update deployment to include observability environment variables - Update deployment to expose metrics port (9090) - Update service to expose metrics port - Add ServiceMonitor template for Prometheus Operator - Add PrometheusRule template with critical and warning alerts **Dashboards:** - Add comprehensive Grafana dashboard JSON with 6 panels: - Request Rate (by method and endpoint) - Error Rate (5xx errors percentage) - Request Latency (P50/P95 by endpoint) - Top MCP Tools (by invocation volume) - Nextcloud API Latency (by app) - Vector Sync Queue Size - Add dashboard README with import instructions **Alert Rules:** - Critical: Server down, high error rate (>5%), high latency (>1s), dependency down - Warning: Token validation errors (>1%), vector sync queue high (>100), Qdrant slow (>500ms) All features are opt-in via values.yaml configuration. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Grafana Dashboards
|
||||
|
||||
This directory contains example Grafana dashboards for monitoring the Nextcloud MCP Server.
|
||||
|
||||
## Dashboards
|
||||
|
||||
### nextcloud-mcp-server.json
|
||||
|
||||
Comprehensive dashboard with the following panels:
|
||||
|
||||
- **Request Rate**: HTTP requests per second by method and endpoint
|
||||
- **Error Rate**: Percentage of 5xx errors
|
||||
- **Request Latency**: P50 and P95 latency by endpoint
|
||||
- **Top MCP Tools**: Most frequently called tools
|
||||
- **Nextcloud API Latency**: API call latency by app (notes, calendar, etc.)
|
||||
- **Vector Sync Queue**: Queue size for background document processing
|
||||
|
||||
## Importing to Grafana
|
||||
|
||||
### Manual Import
|
||||
|
||||
1. Open Grafana UI
|
||||
2. Navigate to Dashboards → Import
|
||||
3. Upload `nextcloud-mcp-server.json`
|
||||
4. Select your Prometheus data source
|
||||
5. Click "Import"
|
||||
|
||||
### Automated Import (Kubernetes)
|
||||
|
||||
If using the Grafana Operator or kube-prometheus-stack, you can create a ConfigMap:
|
||||
|
||||
```bash
|
||||
kubectl create configmap nextcloud-mcp-dashboards \
|
||||
--from-file=nextcloud-mcp-server.json \
|
||||
-n monitoring
|
||||
|
||||
# Add label for Grafana sidecar to discover
|
||||
kubectl label configmap nextcloud-mcp-dashboards \
|
||||
grafana_dashboard=1 \
|
||||
-n monitoring
|
||||
```
|
||||
|
||||
Or add to your Helm values:
|
||||
|
||||
```yaml
|
||||
# values.yaml for kube-prometheus-stack
|
||||
grafana:
|
||||
dashboardProviders:
|
||||
dashboardproviders.yaml:
|
||||
apiVersion: 1
|
||||
providers:
|
||||
- name: 'nextcloud-mcp'
|
||||
orgId: 1
|
||||
folder: 'Nextcloud MCP'
|
||||
type: file
|
||||
disableDeletion: false
|
||||
editable: true
|
||||
options:
|
||||
path: /var/lib/grafana/dashboards/nextcloud-mcp
|
||||
|
||||
dashboardsConfigMaps:
|
||||
nextcloud-mcp: nextcloud-mcp-dashboards
|
||||
```
|
||||
|
||||
## Dashboard Variables
|
||||
|
||||
The dashboard includes two variables:
|
||||
|
||||
- **Data Source**: Select your Prometheus data source
|
||||
- **Namespace**: Filter metrics by Kubernetes namespace
|
||||
|
||||
## Customization
|
||||
|
||||
You can customize the dashboard by:
|
||||
|
||||
1. Adjusting refresh rate (default: 30s)
|
||||
2. Modifying time range (default: last 6 hours)
|
||||
3. Adding new panels for specific metrics
|
||||
4. Adjusting thresholds in existing panels
|
||||
|
||||
## Metrics Reference
|
||||
|
||||
All metrics are documented in `/docs/observability.md`. Key metric prefixes:
|
||||
|
||||
- `mcp_http_*` - HTTP server metrics
|
||||
- `mcp_tool_*` - MCP tool invocation metrics
|
||||
- `mcp_nextcloud_api_*` - Nextcloud API call metrics
|
||||
- `mcp_oauth_*` - OAuth token validation metrics
|
||||
- `mcp_vector_sync_*` - Vector database sync metrics
|
||||
- `mcp_db_*` - Database operation metrics
