# net collector
|
|
|
|
The net collector exposes metrics about network interfaces
|
|
|
|
|||
|
|
-|-
|
|
Metric name prefix | `net`
|
|
Data source | Perflib
|
|
Classes | [`Win32_PerfRawData_Tcpip_NetworkInterface`](https://technet.microsoft.com/en-us/security/aa394340(v=vs.80))
|
|
Enabled by default? | Yes
|
|
|
|
## Flags
|
|
|
|
### `--collector.net.nic-include`
|
|
|
|
If given, an interface name needs to match the include regexp in order for the corresponding metrics to be reported
|
|
|
|
### `--collector.net.nic-exclude`
|
|
|
|
If given, an interface name needs to *not* match the exclude regexp in order for the corresponding metrics to be reported
|
|
|
|
### `--collector.net.enabled`
|
|
|
|
Comma-separated list of collectors to use. Defaults to all, if not specified. Supported values are: `metrics`, `nic_addresses`.
|
|
|
|
## Metrics
|
|
|
|
| Name | Description | Type | Labels |
|
|
|------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------|---------|--------------------------------|
|
|
| `windows_net_bytes_received_total` | Total bytes received by interface | counter | `nic` |
|
|
| `windows_net_bytes_sent_total` | Total bytes transmitted by interface | counter | `nic` |
|
|
| `windows_net_bytes_total` | Total bytes received and transmitted by interface | counter | `nic` |
|
|
| `windows_net_output_queue_length_packets` | Length of the output packet queue (in packets). If this is longer than 2, delays occur. | gauge | `nic` |
|
|
| `windows_net_packets_outbound_discarded_total` | Total outbound packets that were chosen to be discarded even though no errors had been detected to prevent transmission | counter | `nic` |
|
|
| `windows_net_packets_outbound_errors_total` | Total packets that could not be transmitted due to errors | counter | `nic` |
|
|
| `windows_net_packets_received_discarded_total` | Total inbound packets that were chosen to be discarded even though no errors had been detected to prevent delivery | counter | `nic` |
|
|
| `windows_net_packets_received_errors_total` | Total packets that could not be received due to errors | counter | `nic` |
|
|
| `windows_net_packets_received_total` | Total packets received by interface | counter | `nic` |
|
|
| `windows_net_packets_received_unknown_total` | Total packets received by interface that were discarded because of an unknown or unsupported protocol | counter | `nic` |
|
|
| `windows_net_packets_total` | Total packets received and transmitted by interface | counter | `nic` |
|
|
| `windows_net_packets_sent_total` | Total packets transmitted by interface | counter | `nic` |
|
|
| `windows_net_current_bandwidth_bytes` | Estimate of the interface's current bandwidth in bytes per second | gauge | `nic` |
|
|
| `windows_net_nic_address_info` | A metric with a constant '1' value labeled with the network interface's address information. | gauge | `nic`, `address`, `family` |
|
|
| `windows_net_nic_info` | A metric with a constant '1' value labeled with the network interface's general information. | gauge | `nic`, `friendly_name`, `mac` |
|
|
| `windows_net_nic_operation_status` | The operational status for the interface as defined in RFC 2863 as IfOperStatus. | gauge | `nic`, `status` |
|
|
| `windows_net_route_info` | A metric with a constant '1' value labeled with the network interface's route information. | gauge | `nic`, `src`, `dest`, `metric` |
|
|
|
|
### Example metric
|
|
Query the rate of transmitted network traffic
|
|
```
|
|
rate(windows_net_bytes_sent_total{instance="localhost"}[2m])
|
|
```
|
|
|
|
## Useful queries
|
|
Get total utilisation of network interface as a percentage
|
|
```
|
|
rate(windows_net_bytes_total{instance="localhost", nic="Microsoft_Hyper_V_Network_Adapter__1"}[2m]) / windows_net_current_bandwidth_bytes{instance="localhost", nic="Microsoft_Hyper_V_Network_Adapter__1"} * 100
|
|
```
|
|
|
|
## Alerting examples
|
|
**prometheus.rules**
|
|
```yaml
|
|
- alert: NetInterfaceUsage
|
|
expr: rate(windows_net_bytes_total[2m]) / windows_net_current_bandwidth_bytes * 100 > 95
|
|
for: 10m
|
|
labels:
|
|
severity: high
|
|
annotations:
|
|
summary: "Network Interface Usage (instance {{ $labels.instance }})"
|
|
description: "Network traffic usage is greater than 95% for interface {{ $labels.nic }}\n VALUE = {{ $value }}\n LABELS: {{ $labels }}"
|

```
