Sampled Flow Monitoring

sFlow (aka "sampled flow") is an industry-standard for packet export at Layer 2 of the OSI model. It provides a means for exporting truncated packets, together with interface counters for the purpose of monitoring network devices including routers, switches, host devices, and wireless access points.

The sFlow Telegraf Plugin allows you to collect the following metrics:

• tags:
  • agent_address
  • source_id_type
  • source_id_index
  • input_ifindex
  • output_ifindex
  • sample_direction
  • header_protocol
  • ether_type
  • src_ip (
  • src_port
  • src_port_name
  • src_mac
  • src_vlan
  • src_priority
  • src_mask_len
  • dst_ip
  • dst_port
  • dst_port_name
  • dst_mac
  • dst_vlan
  • dst_priority
  • dst_mask_len
  • next_hop
  • ip_version
  • ip_protocol
  • ip_dscp
  • ip_ecn
  • tcp_urgent_pointer
• fields/values:
  • bytes
  • drops
  • packets
  • frame_length
  • header_size
  • ip_fragment_offset
  • ip_header_length
  • ip_total_length
  • ip_ttl
  • tcp_header_length
  • tcp_window_size
