sampling

integer

sampling is an optional sampling interval to apply to this slice. For example, a value of 50 means that 1 matching flow in 50 is sampled.

subnetLabels

array

subnetLabels allows you to customize subnets and IPs labeling, such as to identify cluster external workloads or web services. External subnets must be labeled with the prefix EXT:, or not labeled at all, in order to work with default quick filters and some metrics examples provided.

Beware that the subnet labels configured in FlowCollectorSlice are not limited to the flows of the related namespace: any flow in the whole cluster can be labeled using this configuration. However, subnet labels defined in the cluster-scoped FlowCollector take precedence in case of conflicting rules.
