Counts NetFlow v9/IPFIX traffic per VRF, keyed by the VRF ID that the router exports in each flow record.
| Property | Value |
|---|
| GUID | {7FAB8F84-C580-424B-2BA4-B2546D2DB15A} |
| Layer | Flow Record |
| Input | Flows |
| Key type | VRF ID string |
| Implementation | Lua — nf-vrf.lua (trisul_probe/sysplugs/flowhandlers); updated by CPINetflowMeter (PINetflowMeter.cpp) |
| Bucket / Topper | 60 s / 300 s |
| Enabled by default | Yes |
What it measures
- Each v9/IPFIX record that carries field 234 (
ingressVRFID) adds its bytes to the key for that VRF.
- Records without field 234 are not counted. There is no "no VRF" key. NetFlow v5 and sFlow do not update this group.
- To populate the group, configure the router to export the ingress VRF ID in its flow template.
MeterVRF (default TRUE) in the NetFlow config turns it on or off. IPDR mode turns it off.
Keys
The key is VRF: followed by the VRF ID in decimal. The probe does not set a label. Assign names with Set Label/Edit (see Name Resolution).
| Key | Meaning |
|---|
VRF:0 | VRF ID 0, as exported by the router |
VRF:1 | VRF ID 1 |
VRF:1610612737 | VRF ID 1610612737 (0x60000001) |
Special keys
| Key | Meaning |
|---|
SYS:GROUP_TOTALS | Sum of every update made to this group in the interval. One key per record, so this equals the traffic of records that carry a VRF ID. |
