| sFlow
 | |
| #####
 | |
| 
 | |
| VyOS supports sFlow accounting for both IPv4 and IPv6 traffic. The system acts as a flow exporter, and you are free to use it with any compatible collector.
 | |
| 
 | |
| sFlow is a technology that enables monitoring of network traffic by sending sampled packets to a collector device.
 | |
| 
 | |
| The sFlow accounting based on hsflowd https://sflow.net/
 | |
| 
 | |
| Configuration
 | |
| =============
 | |
| 
 | |
| .. cfgcmd:: set system sflow agent-address <address>
 | |
| 
 | |
|    Configure sFlow agent IPv4 or IPv6 address
 | |
| 
 | |
| 
 | |
| .. cfgcmd:: set system sflow agent-interface <interface>
 | |
| 
 | |
|    Configure agent IP address associated with this interface.
 | |
| 
 | |
| 
 | |
| .. cfgcmd:: set system sflow drop-monitor-limit <limit>
 | |
| 
 | |
|    Dropped packets reported on DROPMON Netlink channel by Linux kernel are exported via the standard sFlow v5 extension for reporting dropped packets
 | |
| 
 | |
| .. cfgcmd:: set system sflow interface <interface>
 | |
| 
 | |
|    Configure and enable collection of flow information for the interface identified by <interface>.
 | |
| 
 | |
|    You can configure multiple interfaces which whould participate in sflow accounting.
 | |
| 
 | |
| 
 | |
| .. cfgcmd:: set system sflow polling <sec>
 | |
| 
 | |
|    Configure schedule counter-polling in seconds (default: 30)
 | |
| 
 | |
| .. cfgcmd:: set system sflow sampling-rate <rate>
 | |
| 
 | |
|    Use this command to configure the sampling rate for sFlow accounting (default: 1000)
 | |
| 
 | |
| .. cfgcmd:: set system sflow server <address> port <port>
 | |
| 
 | |
|    Configure address of sFlow collector. sFlow server at <address> can be both listening on an IPv4 or IPv6 address.
 | |
| 
 | |
| 
 | |
| Example
 | |
| =======
 | |
| 
 | |
| .. code-block:: none
 | |
| 
 | |
|   set system sflow agent-address '192.0.2.14'
 | |
|   set system sflow agent-interface 'eth0'
 | |
|   set system sflow drop-monitor-limit '50'
 | |
|   set system sflow interface 'eth0'
 | |
|   set system sflow interface 'eth1'
 | |
|   set system sflow polling '30'
 | |
|   set system sflow sampling-rate '1000'
 | |
|   set system sflow server 192.0.2.1 port '6343'
 | |
|   set system sflow server 203.0.113.23 port '6343'
