# Metrics

### Metrics

Several metrics are reported during intervals to the OpenWiFi Gateway. In general metrics contain traffic counters, neighbor tables, discovered clients.&#x20;

Each OpenWiFi device is capable of sending statistics on SSID, LLDP, and associated Clients learned by the device.&#x20;

Additionally, OpenWiFi devices expose all 802.11 management data within wifi-frames and to assist network troubleshooting and client fingerprinting solutions OpenWiFi provides dhcp-snooping for all possible client exchanges over DHCP and DHCPv6.&#x20;

```
	"metrics": {
		"statistics": {
			"interval": 60,
			"types": [ "ssids", "lldp", "clients" ]
		},
		"health": {
			"interval": 300
		},
		"wifi-frames": {
			"filters": [ "probe",
				"auth",
				"assoc",
				"disassoc",
				"deauth",
				"local-deauth",
				"inactive-deauth",
				"key-mismatch",
				"beacon-report",
				"radar-detected"]
		},
		"dhcp-snooping": {
			"filters": [ "ack", 
								"discover", 
								"offer", 
								"request", 
								"solicit", 
								"reply", 
								"renew" ]
		}   
```

The metrics data is sent to OpenWiFi Gateway at the intervals set where configurable.&#x20;

Metrics must be associated with the interfaces they are to report on. For example, to send DHCP data from LAN to OpenWiFi Gateway, the following configuration would apply.

```
		{
			"name": "LAN",
			"role": "downstream",
			"services": [ "ssh", "lldp", "dhcp-snooping" ],
			"ethernet": [
				{
					"select-ports": [
						"LAN*"
					]
				}
			],
			"ipv4": {
				"addressing": "static",
				"subnet": "192.168.1.1/24",
				"dhcp": {
					"lease-first": 10,
					"lease-count": 100,
					"lease-time": "6h"
				}
			}
		}
	],
```
