|
### What Was Fixed
|
|
|
|
1. **Removed invalid VXLAN/routing subscription paths** that caused errors

## 🚀 Deployment Instructions
|
|
|
|
### 1. Deploy the Stack
|
|
|
|
```bash
|
|
cd monitoring
|
|
docker-compose up -d
|
|
```
|
|
|
|
### 2. Verify No Errors
|
|
|
|
```bash
|
|
# Check gnmic logs - should be CLEAN
|
|
docker logs gnmic | grep -i error
|
|
|
|
# Should see NO "InvalidArgument" errors!
|
|
```
|
|
|
|
### 3. Verify Metrics Collection
|
|
|
|
```bash
|
|
# Check metrics endpoint
|
|
curl http://localhost:9804/metrics | grep gnmic_interfaces | head -10
|
|
|
|
# Check Prometheus is scraping
|
|
curl http://localhost:9090/api/v1/targets | jq '.data.activeTargets[] | select(.job=="gnmic")'
|
|
```
|
|
|
|
### 4. Access Grafana
|
|
|
|
```bash
|
|
# Open browser
|
|
http://localhost:3000
|
|
|
|
# Login: admin/admin (or use anonymous access)
|
|
|
|
# Test query in Explore:
|
|
gnmic_interfaces_interface_state_counters_out_octets{role="spine"}
|
|
```

## 🔄 Optional Enhancements
|
|
|
|
If you want to add more VXLAN-specific telemetry later:
|
|
|
|
### Option 1: Native Arista Paths (Future)
|
|
|
|
```bash
|
|
# Discover paths on a leaf
|
|
ssh admin@172.16.0.25
|
|
bash
|
|
gnmi -get /Sysdb/bridging/vxlan/status
|
|
```
|
|
|
|
Then add to gnmic.yaml:
|
|
```yaml
|
|
subscriptions:
|
|
arista_vxlan:
|
|
paths:
|
|
- /Sysdb/bridging/vxlan/status
|
|
mode: stream
|
|
stream-mode: sample
|
|
sample-interval: 30s
|
|
encoding: json
|
|
```
|
|
|
|
### Option 2: EOS eAPI Exporter
|
|
|
|
Create custom Prometheus exporter that:
|
|
- Runs CLI commands via eAPI
|
|
- Parses output (show vxlan vtep, etc.)
|
|
- Exports as Prometheus metrics
|
|
|
|
### Option 3: Additional Dashboards
|
|
|
|
Create specialized dashboards for:
|
|
- BGP EVPN route details
|
|
- VXLAN tunnel matrix
|
|
- MLAG health details
|
|
- Per-VNI statistics (if native paths found)
|
|
|
|
