Metrics

trivy-operator exposed a /metrics endpoint by default with metrics for vulnerabilities, exposed secrets,rbacassessment and configaudits.

Report Summary

Vunerability

A report summary series exposes the count of checks of each status reported in a given VulnerabilityReport. For example:

trivy_image_vulnerabilities{
    container_name="coredns",image_digest="",image_registry="index.docker.io",image_os_eosl="",image_os_family="",image_os_name="",image_repository="rancher/coredns-coredns",image_tag="1.8.3",name="replicaset-coredns-6488c6fcc6-coredns",namespace="kube-system",resource_kind="ReplicaSet",resource_name="coredns-6488c6fcc6",severity="High"
    } 10

ConfigAudit

A report summary series exposes the count of checks of each status reported in a given ConfigAuditReport. For example:

trivy_resource_configaudits{
    name="daemonset-svclb-traefik",namespace="kube-system",resource_kind="DaemonSet",resource_name="svclb-traefik",severity="High"
    } 2

ConfigAuditInfo

trivy_configaudits_info{
    config_audit_category="car1 category for config audit",config_audit_description="car1 description for config audit",config_audit_id="car1 Id",config_audit_success="false",config_audit_title="car1 config audit title",name="replicaset-nginx-6d4cf56db6",namespace="default",resource_kind="ReplicaSet",resource_name="nginx-6d4cf56db6",severity="Critical"} 1

RbacAssessments

A report summary series exposes the count of checks of each status reported in a given RbacAssessmentsReport. For example:

trivy_role_rbacassessments{
    name="role-6fbccbcb9d",namespace="kube-system",resource_kind="Role",resource_name="6fbccbcb9d",severity="Medium"
    } 1

RbacAssessmentsInfo

Exposes details about RbacAssessments that were discovered in images, enable by setting the EnvVar: OPERATOR_METRICS_RBAC_ASSESSMENT_INFO_ENABLED" envDefault:"false" . For example:

trivy_rbacassessments_info{

ExposedsSecrets

A report summary series exposes the count of checks of each status reported in a given ExposedsSecretsReport. For example:

trivy_image_exposedsecrets{
    container_name="trivy",image_digest="",image_registry="index.docker.io",image_repository="josedonizetti/trivy",image_tag="secrettest",name="pod-tt-reg-test",namespace="default",resource_kind="Pod",resource_name="tt-reg-test",severity="Critical"
    } 1

ExposedsSecretsInfo

Exposes details about secrets that were discovered in images, enable by setting the EnvVar: OPERATOR_METRICS_EXPOSED_SECRET_INFO_ENABLED" envDefault:"false" . For example:

trivy_exposedsecrets_info{
    container_name="trivy",image_digest="",image_registry="index.docker.io",image_repository="josedonizetti/trivy",image_tag="secrettest",name="pod-tt-reg-test",namespace="default",resource_kind="Pod",resource_name="tt-reg-test",secret_category="AWS",secret_rule_id="aws-access-key-id",secret_target="/etc/apt/s3auth.conf",secret_title="AWS Access Key ID",severity="Critical"
    } 1

InfraAssessments

A report summary series exposes the count of checks of each status reported in a given InfraAssessmentsReport. For example:

trivy_resource_infraassessments{
    name="pod-kube-controller-manager-minikube",namespace="kube-system",resource_kind="Pod",resource_name="kube-controller-manager-minikube",severity="Low"
    } 3

InfraAssessmentsInfo

Exposes details about InfraAssessments that were discovered in images, enable by setting the EnvVar: `OPERATOR_METRICS_INFRA_ASSESSMENT_INFO_ENABLED" envDefault:"false"` . For example:

```shell

trivy_infraassessments_info{
    name="pod-kube-apiserver-minikube-6d4cf56db6",namespace="kube-system",infra_assessment_category="car1 category for infra assessment",infra_assessment_description="car1 description for infra assessment",infra_assessment_id="car1 Id",infra_assessment_success="true",infra_assessment_title="car1 infra assessment title",resource_kind="Pod",resource_name="kube-apiserver-minikube-6d4cf56db6",severity="Critical"
    } 1

ClusterComplianceReport

A report summary series exposes the count of checks of each status reported in a given ClusterComplianceReport. For example:

trivy_cluster_compliance{description="National Security Agency - Kubernetes Hardening Guidance",status="Fail",title="nsa"} 12
trivy_cluster_compliance{description="National Security Agency - Kubernetes Hardening Guidance",status="Pass",title="nsa"} 17

ClusterComplianceInfo

Exposes details about ClusterCompliance that were discovered in images, enable by setting the EnvVar: OPERATOR_METRICS_CLUSTER_COMPLIANCE_INFO_ENABLED" envDefault:"false" . For example:

trivy_compliance_info{compliance_id="car1 Id",compliance_name="car1 cluster compliance name",
    description="National Security Agency - Kubernetes Hardening Guidance",severity="MEDIUM",status="Fail",title="nsa"} 1
trivy_compliance_info{compliance_id="car1 Id",compliance_name="car1 cluster compliance name",
    description="National Security Agency - Kubernetes Hardening Guidance",severity="LOW",status="Pass",title="nsa"} 1

Vulnerability ID

Exposing vulnerability ID on metrics by setting the EnvVar: OPERATOR_METRICS_VULN_ID_ENABLED" envDefault:"false"

trivy_vulnerability_id{
    class="os-pkgs",container_name="nginx",fixed_version="",image_digest="",image_registry="index.docker.io",image_repository="library/nginx",image_tag="1.16.1",installed_version="5.3.28+dfsg1-0.5",last_modified_date="2023-06-28T21:16:00Z",name="replicaset-nginx-deployment-559d658b74-nginx",namespace="default",package_type="debian",pkg_path="/app/local",published_date="2023-06-28T21:15:00Z",resource="libdb5.3",resource_kind="ReplicaSet",resource_name="nginx-deployment-559d658b74",severity="Critical",vuln_id="CVE-2019-8457",vuln_score="7.5",vuln_title="sqlite: heap out-of-bound read in function rtreenode()"
} 1

Adding Custom Label to Metrics

User might wants to include custom labels to resource that can be exposed and associated with the Prometheus metrics. this capability can be added by setting the following helm param.

Example:

--set="trivyOperator.reportResourceLabels": "owner"

k8s_label_ prefix will be added to custom label

trivy_resource_configaudits{k8s_label_owner="platform",name="daemonset-svclb-traefik",namespace="kube-system",resource_kind="DaemonSet",resource_name="svclb-traefik",severity="Critical"} 2
