Total East/West Traffic Probe

Found at /predefined_probes/eastwest_traffic

It first identifies all the server facing interfaces and all external router facing interfaces. It then collects samples for each, generates time series and calculates average traffic across configurable time interval. It then perform accumulation to calculate total server traffic, total external router traffic (south-north) and derives total east-west traffic as the difference between the two. It then provides time series showing how these three totals changed over time.

“leaf server traffic counters” processor

Purpose: wires in interface traffic samples (measured in bytes per second) for traffic received on leafs from the servers

Outputs of “leaf server traffic counters” processor

‘server_traffic_counters’: set of traffic samples (for each server facing interface on each leaf) in the receive direction. Each set member has the following keys to identify it: system_id (id of the leaf system, usually serial number), interface (name of the interface).

“server traffic average” processor

Purpose: Calculate average server traffic during period specified by average_period facade parameter. Unit is bytes per second.

Outputs of “server traffic average” processor

‘server_traffic_avg’: set of traffic average values (for each server facing interface on each leaf) in the receive direction. Each set member has the following keys to identify it: system_id (id of the leaf system, usually serial number), interface (name of the interface).

“external router south-north link traffic” processor

Purpose: wires in interface traffic samples (measured in bytes per second) for traffic sent to external routers

Outputs of “external router south-north link traffic” processor

‘external router south-north links traffic average’: set of traffic samples (for each external router facing interface on each device). Each set member has the following keys to identify it: system_id (id of the system, usually serial number), interface (name of the interface).

“external router south-north links traffic average” processor

Purpose: Calculate average traffic for each interface facing external router traffic during period specified by average_period facade parameter. Unit is bytes per second.

Outputs of “external router south-north links traffic average” processor

‘ext_router_interface_traffic_avg’: set of traffic average values (for each external router facing interface on each device). Each set member has the following keys to identify it: system_id (id of the leaf system, usually serial number), interface (name of the interface).

“total server traffic” processor

Purpose: Calculate total server traffic by summing average traffic on each interface attached to servers, in receive direction. Unit is bytes per second.

Outputs of “total server traffic” processor

‘total_server_traffic’: total server traffic average in bytes per second.

“server generated traffic average” processor

Purpose: Calculate total average server traffic over average_period seconds, which is a facade parameter. Unit is bytes per second.

Outputs of “server generated traffic average” processor

‘total_server_generated_traffic_average’: total server traffic average in bytes per second.

“total server traffic history” processor

Purpose: create recent history time series out showing how total average server traffic changed over time. In terms of the number of samples, the time series will hold history_sample_count values (facade parameter). Unit is bytes per second.

Outputs of “total server traffic history” processor

total_server_traffic_history: time series showing total average server traffic over recent history. Unit is bytes per second.

“south-north traffic” processor

Purpose: Calculate total traffic by summing average traffic on each interface facing external router. Unit is bytes per second.

Outputs of “south-north traffic” processor

‘total_outgoing_traffic’: total south-north traffic average in bytes per second.

“outgoing_traffic_average” processor

Purpose: Calculate total south-north traffic over average_period seconds, which is a facade parameter. Unit is bytes per second.

Outputs of “outgoing_traffic_average” processor

‘total_outgoing_traffic_average’: total south-north traffic average in bytes per second.

“south-north traffic history” processor

Purpose: create recent history time series showing how total average south-north traffic changed over time. In terms of the number of samples, the time series will hold history_sample_count values (facade parameter). Unit is bytes per second.

Outputs of “south-north traffic history” processor

total_outgoing_traffic_timeseries: time series showing total average server traffic over recent history. Unit is bytes per second.

“east-west traffic” processor

Purpose: Subtract south-north traffic from total server traffic to obtain total east-west traffic average, in bytes per second.

Outputs of “east-west traffic” processor

‘eastwest_traffic’: Total average east-west traffic over last average_period seconds, in bytes per second.

“east-west traffic history” processor

Purpose: create recent history time series showing how total average east-west traffic changed over time. In terms of the number of samples, the time series will hold history_sample_count values (facade parameter). Unit is bytes per second.

Outputs of “east-west traffic history” processor

eastwest_traffic_history: time series showing how total average east-west traffic changed over recent history. Unit is bytes per second.
