Metrics for Venafi Enhanced Issuer¶

Overview¶

The Venafi Enhanced Issuer component exposes operational and usage telemetry metrics suitable for popular monitoring solutions, enabling alerts on important operational states.

Health metrics assist in evaluating the readiness of the configured VenafiIssuer and VenafiClusterIssuer resources.

Resource metrics helps the monitoring of CPU, networking, and other resources used by the Venafi Enhanced Issuer on its host.

Operational metrics related to certificate requests help identify conditions that may indicate potential malfunctions, incorrect configurations, or misuse.

All metrics formatted in Prometheus format are available at the standard /metrics path. They can be accessed using the configured HTTP port of the controller component.

Enabling metrics¶

You need Venafi Enhanced Issuer version 0.10.0 or later to use Prometheus metrics. The metrics aren't enabled by default. The example configuration below enables the metrics and specifies the interval at which metrics should be scraped.

To enable the metrics, see the instructions on deploying Venafi Enhanced Issuer, and add the following to the Helm values file:

venafi-enhanced-issuer.values.yaml

metrics:
  enabled: true
  podmonitor:
    enabled: true

There are various metrics configuration options in the Helm chart.

Component information metrics¶

This metric enables you to view the version and commit number of the Venafi Enhanced Issuer component.

venafienhancedissuer_info: A gauge metric indicating the version of the component.

Labels
- version: The version number of the component.
- commit: The commit number of the component.

Health status of `VenafiIssuer` and `VenafiClusterIssuer` resources metrics¶

VenafiIssuer and VenafiClusterIssuer are Kubernetes resources representing certificate authorities (CAs) capable of generating signed certificates by processing certificate signing requests. All cert-manager certificates require a referenced issuer that is in a ready condition in order to attempt certificate enrollment.

The two metrics indicate the location and the current status of the Issuer and ClusterIssuer resources.

venafienhancedissuer_venafiissuer_ready_status: A gauge metric for the health status of VenafiIssuer resources.
venafienhancedissuer_venaficlusterissuer_ready_status: A gauge metric for the health status of VenafiClusterIssuer resources.

Labels
- name: The name of the issuer resource.
- namespace: The namespace of the issuer resource.
- venafi_connection_name: The name of the VenafiConnection resource used by the current issuer.
- ready_status: The status of the issuer. Possible values are True, False, Unknown.
- ready_reason: The reason for the current issuer status. Possible values are Pending and Checked. Checked indicates that the connection to Venafi Control Plane or Venafi TLS Protect Datacenter has been verified and is functioning properly.

Alerts

If you notice issuers with a ready_status value of False or Unknown, it may impact the certificate enrollment and renewal operations for certificates associated with the affected issuer. This has the potential to result in the inability to obtain a certificate, leading to potential application malfunctions.

To diagnose the problem, list the issuers with the following command:

$ kubectl get venafiissuer,venaficlusterissuer --all-namespaces
NAME                                READY   REASON    MESSAGE
venafiissuer.jetstack.io/issuer-4   False   Pending   Not ready yet: VenafiConnection.jetstack.io "example" not found

In the above example, the name provided to venafiConnectionName was incorrect; changing it to the correct value fixed the issue.

Status of the certificate requests metrics¶

The CertificateRequest is a resource used for requesting X.509 certificates from an cert-manager issuer. The resource includes the certificate signing request (CSR) sent to the referenced issuer. Upon successful issuance, it returns a signed certificate based on the CSR.

venafienhancedissuer_certificaterequest_ready_status is a gauge metric that contains the count of certificate requests for all issuers (not limited to VenafiIssuer and VenafiClusterIssuer). It provides additional details on the location of the certificate request resource and its status. The metric also includes information about the referenced cert-manager issuer.

venafienhancedissuer_certificaterequest_ready_status: A gauge metric for the requested certificate requests.

Labels
- namespace: The namespace of the certificate request resource.
- ready_status: The status of the certificate request. Possible values are True, False, Unknown.
- ready_reason: The reason for the current status of the certificate request. Possible values are Pending, Failed, Denied, Issued, and Initializing.
- issuer_name: The name of the issuer which processed the certificate request.
- issuer_kind: The kind of the issuer which processed the certificate request.
- issuer_group: The group of the issuer which processed the certificate request.

Alerts

Monitoring the count of venafienhancedissuer_certificaterequest_ready_status allows you to understand the certificate enrollment process across the Kubernetes cluster. Certificate requests with ready_status equal to False require investigation. For instance, an increase in failed certificate requests with ready_reason equal to Denied suggests a potential attempt of mis-issuance or mis-configuration.

Here are some kubectl commands to help you find and examine the offending CertificateRequest resources in your cluster:

Troubleshooting `CertificateRequest` resources¶

If there are CertificateRequest resources which are not Ready

Use the following command to find all unready CertificateRequest resources in all namespaces, and show only the name, namespace and Ready condition of each resource:

kubectl wait certificaterequest \
    --all-namespaces \
    --all \
    --timeout 0 \
    --output json \
    --for condition=Ready=false \
    2>stderr.txt \
    | jq '{"name": .metadata.name, "namespace": .metadata.namespace, "ready-condition": .status.conditions[] | select(.type=="Ready")}'

If there are Denied CertificateRequest resources

First, find the offending CertificateRequest resources.

You can use following command to find all Denied CertificateRequest resources in all namespaces, and show only the name, namespace and Denied condition of each resource:

kubectl wait certificaterequest \
    --all-namespaces \
    --all \
    --timeout 0 \
    --output json \
    --for condition=Denied=True \
    2>stderr.txt \
    | jq '{"name": .metadata.name, "namespace": .metadata.namespace, "denied-condition": .status.conditions[] | select(.type=="Denied")}'

Problems¶

Here is an example of a failure caused by a CertificateRequestPolicy violation:

{
  "name": "issuer-2-policy-fails-cert-42-1",
  "namespace": "default",
  "denied-condition": {
    "lastTransitionTime": "2023-11-29T23:09:41Z",
    "message": "No policy approved this request: [issuer-2: spec.allowed.dnsNames.values: Invalid value: []string{\"forbidden-domain-42.com\"}: *.example.com, *.ca-wont-accept.org] [mael: common name forbidden-domain-42.com is not allowed in this policy: [^.*.example.com$ ^.*.example.org$ ^.*.example.net$ ^.*.invalid$ ^.*.local$ ^.*.localhost$ ^.*.test$]]",
    "reason": "policy.cert-manager.io",
    "status": "True",
    "type": "Denied"
  }
}

In this example, there are two problems:

Non-compliance with CertificateRequestPolicy named issuer-2

The DNS names in the CertificateRequest do not comply with the DNS domain patterns allowed by the CertificateRequestPolicy called issuer-2.

Non-compliance with CertificateRequestPolicy named mael

The common name of the CertificateRequest does not comply with common name patterns allowed by the CertificateRequestPolicy called mael.

Possible Causes¶

There are three possible causes of this problem:

The team responsible for this CertificateRequest may be creating inappropriate CertificateRequest resources.
The policy in the CertificateRequestPolicy resources may be wrong.
The CertificateRequestPolicy selector may be wrong.

The team responsible for this CertificateRequest may be creating inappropriate CertificateRequest resources

If they have examined the CertificateRequest resource, the application team will be aware of the policy violations. They should know what the problem is by looking at the condition and events, and they should create another CertificateRequest using compliant DNS names. No further action should be required from the platform team, unless the application team fails to correct the problem themselves.

The policy in the CertificateRequestPolicy resources may be wrong

As a platform administrator you should examine the CertificateRequestPolicy resources to understand how they are configured, and to double-check that the policy rules are appropriate.

Use the following kubectl describe command to show a summary of the two CertificateRequestPolicy resources that have been applied to this CertificateRequest:

kubectl describe CertificateRequestPolicy issuer-2 mael

The CertificateRequestPolicy called issuer-2 uses built-in policy settings. For more information, see the approver-policy API reference.

$ kubectl describe CertificateRequestPolicy issuer-2

Check that these policy rules are appropriate for the CertificateRequest resources that they are being applied to.

The CertificateRequestPolicy called mael uses the Plugins.Venafi stanza, which means that it is connected to Venafi:

  Normal  Ready   8m41s (x161 over 2d8h)  policy.cert-manager.io  CertificateRequestPolicy is ready for approval evaluation

This CertificateRequestPolicy is Ready, so you can be confident that the policy rules have been successfully downloaded from the Venafi TPP server. These policy rules are maintained in Venafi TPP by the InfoSec team, as a platform administrator you can communicate with the InfoSec team and ask them to relax the policy rules if necessary, or ask them to suggest a different Venafi policy "zone" which might be more appropriate.

The CertificateRequestPolicy selector may be wrong

As a platform administrator you might conclude that CertificateRequest resource has been matched to the wrong CertificateRequestPolicy resources. In this case, it's your responsibility to adjust the CertificateRequestPolicy selector fields.

For more information, see the CertificateRequestPolicy selector field configuration instructions.

Health of the Venafi Connection metrics¶

The Venafi Connection resource venaficonnection_status indicates if connection to the Venafi API is successful or not with respect to which service is using the connection.

Labels¶

name: The name of the Venafi Connection resource.
namespace: The name of the service that is using the connection.
cond_type: This string represents the name of the component for which cond_status applies. The possible values are VenafiEnhancedIssuerReady and ApproverPolicyVenafiReady.
cond_status: The possible values are True (the connection to the Venafi service is OK) or False (the connection or authentication is failing).

For example, the following line means that the Venafi Connection conn is being used by the Approver Policy Enterprise component, and that the connection between Approver Policy Enterprise and Venafi is failing:

venaficonnection_status{name="conn",namespace="venafi",ready_status="False",cond_type="ApproverPolicyVenafiReady"} 1

Alerts¶

Venafi Connection resources with the condition type VenafiEnhancedIssuerReady or ApproverPolicyEnterpriseReady equal to False must be investigated. This will alert you when a component is unable to connect to the Venafi API.

If you have jq installed, you can identify the component that is using the connection. Use the following command to list the Venafi Connection resources:

kubectl get venaficonnection --all-namespaces -o json \
  | jq -r '.items[] | select(.status.conditions[].status == "True") | "\(.metadata.namespace) \(.metadata.name)"'

Once you have identified the Venafi Connection resource that contain a False condition, you can debug the problem by displaying its events:

kubectl describe venaficonnection -n <namespace> <name>

Latency and status codes of the HTTP requests metrics¶

These two metrics represent the latency and status codes of the HTTP requests to Venafi Control Plane and Venafi TLS Protect Datacenter.

vcert_http_request_duration_seconds_bucket: A histogram metric indicating the durations of requests to Venafi Control Plane and Venafi TLS Protect Datacenter.

Labels
- method: The HTTP method (for example, POST) of the request.
- path: The HTTP path of the request (for example, /outagedetection/v1/certificaterequests).
- host: The HTTP Host header of the request (for example, api.venafi.cloud).
- le: The time between the invocation of the HTTP request and the corresponding response.
vcert_http_requests_total: A counter metric indicating the total number of HTTP requests to Venafi Control Plane and Venafi TLS Protect Datacenter.

Labels
- method: The HTTP method (for example, POST) of the request.
- path: The HTTP path of the request (for example, /outagedetection/v1/certificaterequests).
- host: The HTTP Host header of the request (for example, api.venafi.cloud).
- code: The HTTP status code (for example, 200).

Alerts

If you notice a significant increase in failed HTTP requests (vcert_http_requests_total with code equal to or higher than 400), it's crucial to investigate the root cause of this issue.

The metric vcert_http_request_duration_seconds_bucket, when averaged, measures how fast Venafi Control Plane and Venafi TLS Protect Datacenter respond to requests from Venafi Enhanced Issuer. If you notice a significant increase in this metric, this requires investigation.

CPU and memory metrics¶

The CPU and memory metrics are provided by Kubernetes. The kubelet processes running on each Kubernetes node expose the endpoint /metrics/resources which, when scraped, provide the two following metrics (among others):

container_memory_usage_bytes
container_cpu_usage_seconds_total

Tip

If you are using Prometheus and have installed it through the kube-prometheus operator, the metrics are already available to you. To install the kube-prometheus operator, see the Getting Started tutorial.

Visualizing metrics¶

Venafi offers a sample Grafana dashboard in JSON format for you to import into your Grafana instance.
