Type
object
PropertyTypeDescription

agent

object

Agent configuration for flows extraction.

consolePlugin

object

consolePlugin defines the settings related to the OpenShift Container Platform Console plugin, when available.

deploymentModel

string

deploymentModel defines the desired type of deployment for flow processing. Possible values are:

- Direct (default) to make the flow processor listen directly from the agents.

- Kafka to make flows sent to a Kafka pipeline before consumption by the processor.

Kafka can provide better scalability, resiliency, and high availability (for more details, see https://www.redhat.com/en/topics/integration/what-is-apache-kafka).

exporters

array

exporters define additional optional exporters for custom consumption or storage.

kafka

object

Kafka configuration, allowing to use Kafka as a broker as part of the flow collection pipeline. Available when the spec.deploymentModel is Kafka.

loki

object

namespace

string

Namespace where Network Observability pods are deployed.

networkPolicy

object

13.1.3. .spec.agent

Description
Agent configuration for flows extraction.
Type
object
PropertyTypeDescription

ebpf

object

ebpf describes the settings related to the eBPF-based flow reporter when spec.agent.type is set to eBPF.

type

string

type [deprecated (*)] selects the flows tracing agent. Previously, this field allowed to select between eBPF or IPFIX. Only eBPF is allowed now, so this field is deprecated and is planned for removal in a future version of the API.

13.1.4. .spec.agent.ebpf

Description
ebpf describes the settings related to the eBPF-based flow reporter when spec.agent.type is set to eBPF.
Type
object
PropertyTypeDescription

advanced

object

advanced allows setting some aspects of the internal configuration of the eBPF agent. This section is aimed mostly for debugging and fine-grained performance optimizations, such as GOGC and GOMAXPROCS env vars. Set these values at your own risk.

cacheActiveTimeout

string

cacheActiveTimeout is the max period during which the reporter aggregates flows before sending. Increasing cacheMaxFlows and cacheActiveTimeout can decrease the network traffic overhead and the CPU load, however you can expect higher memory consumption and an increased latency in the flow collection.

cacheMaxFlows

integer

cacheMaxFlows is the max number of flows in an aggregate; when reached, the reporter sends the flows. Increasing cacheMaxFlows and cacheActiveTimeout can decrease the network traffic overhead and the CPU load, however you can expect higher memory consumption and an increased latency in the flow collection.

excludeInterfaces

array (string)

excludeInterfaces contains the interface names that are excluded from flow tracing. An entry enclosed by slashes, such as /br-/, is matched as a regular expression. Otherwise it is matched as a case-sensitive string.

features

array (string)

List of additional features to enable. They are all disabled by default. Enabling additional features might have performance impacts. Possible values are:

- PacketDrop: enable the packets drop flows logging feature. This feature requires mounting the kernel debug filesystem, so the eBPF agent pods have to run as privileged. If the spec.agent.ebpf.privileged parameter is not set, an error is reported.

- DNSTracking: enable the DNS tracking feature.

- FlowRTT: enable flow latency (sRTT) extraction in the eBPF agent from TCP traffic.

- NetworkEvents: enable the network events monitoring feature, such as correlating flows and network policies. This feature requires mounting the kernel debug filesystem, so the eBPF agent pods have to run as privileged. It requires using the OVN-Kubernetes network plugin with the Observability feature. IMPORTANT: This feature is available as a Developer Preview.

flowFilter

object

flowFilter defines the eBPF agent configuration regarding flow filtering.

imagePullPolicy

string

imagePullPolicy is the Kubernetes pull policy for the image defined above

interfaces

array (string)

interfaces contains the interface names from where flows are collected. If empty, the agent fetches all the interfaces in the system, excepting the ones listed in excludeInterfaces. An entry enclosed by slashes, such as /br-/, is matched as a regular expression. Otherwise it is matched as a case-sensitive string.

metrics

object

metrics defines the eBPF agent configuration regarding metrics.

privileged

boolean

Privileged mode for the eBPF Agent container. When ignored or set to false, the operator sets granular capabilities (BPF, PERFMON, NET_ADMIN, SYS_RESOURCE) to the container. If for some reason these capabilities cannot be set, such as if an old kernel version not knowing CAP_BPF is in use, then you can turn on this mode for more global privileges. Some agent features require the privileged mode, such as packet drops tracking (see features) and SR-IOV support.

resources

object

resources are the compute resources required by this container. For more information, see https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

sampling

Note that the more metrics you add, the bigger is the impact on Prometheus workload resources. Metrics enabled by default are: namespace_flows_total, node_ingress_bytes_total, node_egress_bytes_total, workload_ingress_bytes_total, workload_egress_bytes_total, namespace_drop_packets_total (when PacketDrop feature is enabled), namespace_rtt_seconds (when FlowRTT feature is enabled), namespace_dns_latency_seconds (when DNSTracking feature is enabled).

integer-or-string

Requests describes the minimum amount of compute resources required. If Requests is omitted for a container, it defaults to Limits if that is explicitly specified, otherwise to an implementation-defined value. Requests cannot exceed Limits. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

13.1.84. .spec.processor.subnetLabels

Description
subnetLabels allows to define custom labels on subnets and IPs or to enable automatic labelling of recognized subnets in OpenShift Container Platform, which is used to identify cluster external traffic. When a subnet matches the source or destination IP of a flow, a corresponding field is added: SrcSubnetLabel or DstSubnetLabel.
Type
object
PropertyTypeDescription

customLabels

array

customLabels allows to customize subnets and IPs labelling, such as to identify cluster-external workloads or web services. If you enable openShiftAutoDetect, customLabels can override the detected subnets in case they overlap.

openShiftAutoDetect

boolean

openShiftAutoDetect allows, when set to true, to detect automatically the machines, pods and services subnets based on the OpenShift Container Platform install configuration and the Cluster Network Operator configuration. Indirectly, this is a way to accurately detect external traffic: flows that are not labeled for those subnets are external to the cluster. Enabled by default on OpenShift Container Platform.

13.1.85. .spec.processor.subnetLabels.customLabels

Description
customLabels allows to customize subnets and IPs labelling, such as to identify cluster-external workloads or web services. If you enable openShiftAutoDetect, customLabels can override the detected subnets in case they overlap.

Type
object
PropertyTypeDescription

querier

object

Prometheus querying configuration, such as client settings, used in the Console plugin.

13.1.88. .spec.prometheus.querier

Description
Prometheus querying configuration, such as client settings, used in the Console plugin.
Type
object
Required
  • mode
PropertyTypeDescription

enable

boolean

When enable is true, the Console plugin queries flow metrics from Prometheus instead of Loki whenever possible. It is enbaled by default: set it to false to disable this feature. The Console plugin can use either Loki or Prometheus as a data source for metrics (see also spec.loki), or both. Not all queries are transposable from Loki to Prometheus. Hence, if Loki is disabled, some features of the plugin are disabled as well, such as getting per-pod information or viewing raw flows. If both Prometheus and Loki are enabled, Prometheus takes precedence and Loki is used as a fallback for queries that Prometheus cannot handle. If they are both disabled, the Console plugin is not deployed.

manual

object

Prometheus configuration for Manual mode.

mode

string

mode must be set according to the type of Prometheus installation that stores Network Observability metrics:

- Use Auto to try configuring automatically. In OpenShift Container Platform, it uses the Thanos querier from OpenShift Container Platform Cluster Monitoring

- Use Manual for a manual setup

timeout

string

timeout is the read timeout for console plugin queries to Prometheus. A timeout of zero means no timeout.

13.1.89. .spec.prometheus.querier.manual
