Alerts
The following alerts are available:
| Alert name | On metric | Description |
|---|---|---|
| interface_speed | net.net | network interface ${label:device} current speed |
| 1m_received_traffic_overflow | net.net | average inbound utilization for the network interface ${label:device} over the last minute |
| 1m_sent_traffic_overflow | net.net | average outbound utilization for the network interface ${label:device} over the last minute |
| inbound_packets_dropped_ratio | net.drops | ratio of inbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| outbound_packets_dropped_ratio | net.drops | ratio of outbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| wifi_inbound_packets_dropped_ratio | net.drops | ratio of inbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| wifi_outbound_packets_dropped_ratio | net.drops | ratio of outbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| 1m_received_packets_rate | net.packets | average number of packets received by the network interface ${label:device} over the last minute |
| 10s_received_packets_storm | net.packets | ratio of average number of received packets for the network interface ${label:device} over the last 10 seconds, compared to the rate over the last minute |
| 10min_fifo_errors | net.fifo | number of FIFO errors for the network interface ${label:device} in the last 10 minutes |
Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per Network interfaces instance
This scope has no labels.
Metrics:
| Metric | Description | Dimensions | Unit |
|---|---|---|---|
| system.net | Physical Network Interfaces Aggregated Bandwidth | received, sent | kilobits/s |
Per network device
Labels:
| Label | Description |
|---|---|
| interface_type | Either virtual (for virtual/software interfaces) or real (for physical interfaces). |
| device | The network interface name (e.g., eth0, wlan0). |
Metrics:
| Metric | Description | Dimensions | Unit |
|---|---|---|---|
| net.net | Bandwidth | received, sent | kilobits/s |
| net.speed | Interface Speed | speed | kilobits/s |
| net.duplex | Interface Duplex State | full, half, unknown | state |
| net.operstate | Interface Operational State | up, down, notpresent, lowerlayerdown, testing, dormant, unknown | state |
| net.carrier | Interface Physical Link State | up, down | state |
| net.mtu | Interface MTU | mtu | octets |
| net.packets | Packets | received, sent, multicast | packets/s |
| net.errors | Interface Errors | inbound, outbound | errors/s |
| net.drops | Interface Drops | inbound, outbound | drops/s |
| net.fifo | Interface FIFO Buffer Errors | receive, transmit | errors |
| net.compressed | Compressed Packets | received, sent | packets/s |
| net.events | Network Interface Events | frames, collisions, carrier | events/s |
