Advanced Configuration

The values.yaml lists all supported configurable parameters for this chart, along with detailed explanation. Read through it to understand how to configure this chart.

Also check examples of chart configuration. This also includes a guide to deploy for the k8s cluster with the windows worker node.

At the minimum you need to configure the following values to send data to Splunk Enterprise/Cloud.

splunkPlatform:
  token: xxxxxx
  endpoint: http://localhost:8088/services/collector

At the minimum you need to configure the following values to send data to Splunk Observability Cloud.

splunkObservability:
  accessToken: xxxxxx
  realm: us0
clusterName: my-k8s-cluster

Cloud provider

Use the cloudProvider parameter to provide information about the cloud provider, if any.

aws - Amazon Web Services
gcp - Google Cloud
azure - Microsoft Azure

This value can be omitted if none of the values apply.

Kubernetes distribution

Use the distribution parameter to provide information about underlying Kubernetes deployment. This parameter allows the collector to automatically scrape additional metadata. The supported options are:

aks - Azure AKS
eks - Amazon EKS
eks/fargate - Amazon EKS with Fargate profiles
gke - Google GKE / Standard mode
gke/autopilot - Google GKE / Autopilot mode
openshift - Red Hat OpenShift

This value can be omitted if none of the values apply.

Deployment environment

Optional environment parameter can be used to specify an additional deployment.environment attribute that will be added to all the telemetry data. It will help Splunk Observability users to investigate data coming from different source separately. Value examples: development, staging, production, etc.

environment: production

Disable particular types of telemetry

By default only metrics and traces are sent to Splunk Observability destination, and only logs are sent to Splunk Platform destination. It's possible to enable or disable any kind of telemetry for a specific destination. For example, with the following configuration Splunk OTel Collector will send all collected telemetry data to Splunk Observability and Splunk Platform assuming they are both properly configured.

splunkObservability:
  metricsEnabled: true
  tracesEnabled: true
  logsEnabled: true
splunkPlatform:
  metricsEnabled: true
  logsEnabled: true

Windows worker nodes support

Splunk OpenTelemetry Collector for Kubernetes supports collection of metrics, traces and logs (using OTel native logs collection only) from Windows nodes.

All windows images are available in a separate quay.io repository: quay.io/signalfx/splunk-otel-collector-windows.

Use the following values.yaml configuration to install the helm chart on Windows worker nodes:

isWindows: true
image:
  otelcol:
    repository: quay.io/signalfx/splunk-otel-collector-windows
logsEngine: otel
readinessProbe:
  initialDelaySeconds: 60
livenessProbe:
  initialDelaySeconds: 60

If you have both Windows and Linux worker nodes in your Kubernetes cluster, you need to install the helm chart twice. One of the installations with default configuration isWindows: false will be applied on Linux nodes. Another installation with values.yaml configuration that provided above will be applied on Windows nodes. And it's important to disable clusterReceiver on one of the installations to avoid cluster-wide metrics duplication, add the following line to values.yaml of one of the installations:

clusterReceiver:
  enabled: false

GKE Autopilot support

If you want to run Splunk OTel Collector in Google Kubernetes Engine Autopilot, make sure to set distribution setting to gke/autopilot:

distribution: gke/autopilot

NOTE: Native OTel logs collection is not yet supported in GKE Autopilot.

Sometimes Splunk OTel Collector agent daemonset can have problems scheduling in Autopilot If you run into these issues, you can assign the daemonset a higher priority class, this will make sure that the daemonset pods are always present on each node:

Create a new priority class for Splunk OTel Collector agent:

cat <<EOF | kubectl apply -f -
apiVersion: scheduling.k8s.io/v1
kind: PriorityClass
metadata:
  name: splunk-otel-agent-priority
value: 1000000
globalDefault: false
description: "Higher priority class for Splunk OpenTelemetry Collector pods."
EOF

Use the created priority class in the helm install/upgrade command: with --set="priorityClassName=splunk-otel-agent-priority" cli argument or add the following line to your custom values.yaml:

priorityClassName: splunk-otel-agent-priority

GKE ARM support

We support ARM workloads on GKE with default configurations of this helm chart. Make sure to set the required distribution value to gke:

distribution: gke

EKS Fargate support

If you want to run the Splunk OpenTelemetry Collector in Amazon Elastic Kubernetes Service with Fargate profiles, make sure to set the required distribution value to eks/fargate:

distribution: eks/fargate

NOTE: Fluentd and Native OTel logs collection are not yet automatically configured in EKS with Fargate profiles

This distribution will operate similarly to the eks distribution but with the following distinctions:

The Collector agent daemonset is not applied since Fargate doesn't support daemonsets. Any desired Collector instances running as agents must be configured manually as sidecar containers in your custom deployments. This includes any application logging services like Fluentd. We recommend setting the gateway.enabled to true and configuring your instrumented applications to report metrics, traces, and logs to the gateway's <installed-chart-name>-splunk-otel-collector service address. Any desired agent instances that would run as a daemonset should instead run as sidecar containers in your pods.
Since Fargate nodes use a VM boundary to prevent access to host-based resources used by other pods, pods are not able to reach their own kubelet. The cluster receiver for the Fargate distribution has two primary differences between regular eks to work around this limitation:
- The configured cluster receiver is deployed as a 2-replica StatefulSet instead of a Deployment and uses a Kubernetes Observer extension that discovers the cluster's nodes and, on the second replica, its pods for user-configurable receiver creator additions. It uses this observer to dynamically create Kubelet Stats receiver instances that will report kubelet metrics for all observed Fargate nodes. The first replica will monitor the cluster with a k8s_cluster receiver and the second will monitor all kubelets except its own (due to an EKS/Fargate networking restriction).
- The first replica's collector will monitor the second's kubelet. This is made possible by a Fargate-specific splunk-otel-eks-fargate-kubeletstats-receiver-node node label. The Collector's ClusterRole for eks/fargate will allow the patch verb on nodes resources for the default API groups to allow the cluster receiver's init container to add this node label for designated self monitoring.

Control Plane metrics

By setting agent.controlPlaneMetrics.{component}.enabled=true the helm chart will set up the otel-collector agent to collect metrics from a particular control plane component. Most metrics can be collected from the control plane with no extra configuration, however, extra configuration steps must be taken to collect metrics from etcd ( see below ) due to TLS security requirements.

To collect control plane metrics, the helm chart has the otel-collector agent on each node use the receiver creator to instantiate control plane receivers at runtime. The receiver creator has a set of discovery rules to know which control plane receivers to create. The default discovery rules can vary depending on the Kubernetes distribution and version. If your control plane is using nonstandard specs, then you can provide a custom configuration ( see below ) so the otel-collector agent can still successfully connect.

The otel-collector agent relies on having pod level network access to collect metrics from the control plane pods. Since most cloud Kubernetes as a service distributions don't expose the control plane pods to the end user, collecting metrics from these distributions is not supported.

Supported Distributions:
- kubernetes 1.22 (kops created)
- openshift v4.9
Unsupported Distributions:
- aks
- eks
- eks/fargate
- gke
- gke/autopilot

The default configurations for the control plane receivers can be found in _otel-agent.tpl.

Setting up etcd metrics

The etcd metrics cannot be collected out of box because etcd requires TLS authentication for communication. Below, we have supplied a couple methods for setting up TLS authentication between etcd and the otel-collector agent. The etcd TLS client certificate and key play a critical role in the security of the cluster, handle them with care and avoid storing them in unsecured locations. To limit unnecessary access to the etcd certificate and key, you should deploy the helm chart into a namespace that is isolated from other unrelated resources.

Method 1: Deploy the helm chart with the etcd certificate and key as values

The easiest way to set up the TLS authentication for etcd metrics is to retrieve the client certificate and key from an etcd pod and directly use them in the values.yaml (or using --set=). The helm chart will set up the rest. The helm chart will add the client certificate and key to a newly created kubernetes secret and then configure the etcd receiver to use them.

You can get the contents of the certificate and key by running these commands. The path to the certificate and key can vary depending on your Kubernetes distribution.

# The steps for kubernetes and openshift are listed here.
# For kubernetes:
etcd_pod_name=$(kubectl get pods -n kube-system -l k8s-app=etcd-manager-events -o=name |  sed "s/^.\{4\}//" | head -n 1)
kubectl exec -it -n kube-system {etcd_pod_name} cat /etc/kubernetes/pki/etcd-manager/etcd-clients-ca.crt
kubectl exec -it -n kube-system {etcd_pod_name} cat /etc/kubernetes/pki/etcd-manager/etcd-clients-ca.key
# For openshift:
etcd_pod_name=$(kubectl get pods -n openshift-etcd -l k8s-app=etcd -o=name |  sed "s/^.\{4\}//" | head -n 1)
kubectl exec -it -n openshift-etcd {etcd_pod_name} cat /etc/kubernetes/static-pod-certs/secrets/etcd-all-certs/etcd-serving-metrics-{etcd_pod_name}.crt
kubectl exec -it -n openshift-etcd {etcd_pod_name} cat /etc/kubernetes/static-pod-certs/secrets/etcd-all-certs/etcd-serving-metrics-{etcd_pod_name}.key

Once you have the contents of your certificate and key, insert them into your values.yaml. Since the helm chart will create the secret, you must specify agent.controlPlaneMetrics.etcd.secret.create=true. Then install your helm chart.

agent:
  controlPlaneMetrics:
    etcd:
      enabled: true
      secret:
        create: true
        # The PEM-format CA certificate for this client.
        clientCert: |
          -----BEGIN CERTIFICATE-----
          ...
          -----END CERTIFICATE-----
        # The private key for this client.
        clientKey: |
          -----BEGIN RSA PRIVATE KEY-----
          ...
          -----END RSA PRIVATE KEY-----
        # Optional. The CA cert that has signed the TLS cert.
        # caFile: |

Method 2: Deploy the helm chart with a secret that contains the etcd certificate and key

To set up the TLS authentication for etcd metrics with this method, the otel-collector agents will need access to a kubernetes secret that contains the etcd TLS client certificate and key. The name of this kubernetes secret must be supplied in the helm chart (.Values.agent.controlPlaneMetrics.etcd.secret.name). When installed, the helm chart will mount the specified kubernetes secret onto the /otel/etc/etcd directory of the otel-collector agent containers so the agent can use it.

Here are the commands for creating a kubernetes secret named splunk-monitoring-etcd.

# The steps for kubernetes and openshift are listed here.
# For kubernetes:
etcd_pod_name=$(kubectl get pods -n kube-system -l k8s-app=etcd-manager-events -o=name |  sed "s/^.\{4\}//" | head -n 1)
kubectl exec -it -n kube-system $etcd_pod_name -- cat /etc/kubernetes/pki/etcd-manager/etcd-clients-ca.crt > ./tls.crt
kubectl exec -it -n kube-system $etcd_pod_name -- cat /etc/kubernetes/pki/etcd-manager/etcd-clients-ca.key > ./tls.key
# For openshift:
etcd_pod_name=$(kubectl get pods -n openshift-etcd -l k8s-app=etcd -o=name |  sed "s/^.\{4\}//" | head -n 1)
kubectl exec -it -n openshift-etcd {etcd_pod_name} cat /etc/kubernetes/static-pod-certs/secrets/etcd-all-certs/etcd-serving-metrics-{etcd_pod_name}.crt > ./tls.crt
kubectl exec -it -n openshift-etcd {etcd_pod_name} cat /etc/kubernetes/static-pod-certs/secrets/etcd-all-certs/etcd-serving-metrics-{etcd_pod_name}.key > ./tls.key

# Create the the secret.
# The input file names must be one of:  tls.crt, tls.key, cacert.pem
kubectl create secret generic splunk-monitoring-etcd --from-file=./tls.crt --from-file=./tls.key
# Optional. Include the CA cert that has signed the TLS cert.
# kubectl create secret generic splunk-monitoring-etcd --from-file=./tls.crt --from-file=./tls.key --from-file=cacert.pem

# Cleanup the local files.
rm ./tls.crt
rm ./tls.key

Once your kubernetes secret is created, specify the secret's name in values.yaml. Since the helm chart will be using the secret you created, make sure to set .Values.agent.controlPlaneMetrics.etc.secret.create=false. Then install your helm chart.

agent:
  controlPlaneMetrics:
    etcd:
      enabled: true
      secret:
        create: false
        name: splunk-monitoring-etcd

Using custom configurations for nonstandard control plane components

A user may need to override the default configuration values used to connect to the control plane for a couple different reason. If your control plane uses nonstandard ports or custom TLS settings, then you will need to override the default configurations. Here is an example of how you could connect to a nonstandard apiserver that uses port 3443 for metrics and custom TLS certs stored in the /etc/myapiserver/ directory.

agent:
  config:
    receivers:
      receiver_creator:
        receivers:
          # Template for overriding the discovery rule and config.
          # smartagent/{control_plane_receiver}:
          #   rule: {rule_value}
          #   config:
          #     {config_value}
          smartagent/kubernetes-apiserver:
            rule: type == "port" && port == 3443 && pod.labels["k8s-app"] == "kube-apiserver"
            config:
              clientCertPath: /etc/myapiserver/clients-ca.crt
              clientKeyPath: /etc/myapiserver/clients-ca.key
              skipVerify: true
              useHTTPS: true
              useServiceAccount: false

Known issues

Kube Proxy

kubernetes/kops#6472
- Problem
  - When using a kops created Kubernetes cluster, a network connectivity issue has been reported that prevents proxy metrics from being collected.
- Solution
  - This issue can be addressed updating the kubeProxy metric bind address in the kops cluster spec:
    - Set "kubeProxy.metricsBindAddress: 0.0.0.0" in the kops cluster spec.
    - Deploy the change with "kops update cluster {cluster_name}" and "kops rolling-update cluster {cluster_name}".

Logs collection

The helm chart currently utilizes fluentd for Kubernetes logs collection. Logs collected with fluentd are sent through Splunk OTel Collector agent which does all the necessary metadata enrichment.

OpenTelemetry Collector also has native functionality for logs collection. This chart soon will be migrated from fluentd to the OpenTelemetry logs collection.

You already have an option to use OpenTelemetry logs collection instead of fluentd. The following configuration can be used to achieve that:

logsEngine: otel

There are following known limitations of native OTel logs collection:

service.name attribute will not be automatically constructed in istio environment. This means that correlation between logs and traces will not work in Splunk Observability. Logs collection with fluentd is still recommended if chart deployed with autodetect.istio=true.
Not yet supported in GKE Autopilot.

Add log files from Kubernetes host machines/volumes

You can add additional log files to be ingested from Kubernetes host machines and Kubernetes volumes by configuring agent.extraVolumes, agent.extraVolumeMounts and logsCollection.extraFileLogs in the values.yaml file used to deploy Splunk OpenTelemetry Collector for Kubernetes.

Example of adding audit logs from Kubernetes host machines

logsCollection:
  extraFileLogs:
    filelog/audit-log:
      include: [/var/log/kubernetes/apiserver/audit.log]
      start_at: beginning
      include_file_path: true
      include_file_name: false
      resource:
        com.splunk.source: /var/log/kubernetes/apiserver/audit.log
        host.name: 'EXPR(env("K8S_NODE_NAME"))'
        com.splunk.sourcetype: kube:apiserver-audit
agent:
  extraVolumeMounts:
    - name: audit-log
      mountPath: /var/log/kubernetes/apiserver
  extraVolumes:
    - name: audit-log
      hostPath:
        path: /var/log/kubernetes/apiserver

Processing multi-line logs

Splunk OpenTelemetry Collector for Kubernetes supports parsing of multi-line logs to help read, understand, and troubleshoot the multi-line logs in a better way. Process multi-line logs by configuring logsCollection.containers.multilineConfigs section in values.yaml.

logsCollection:
  containers:
    multilineConfigs:
      - namespaceName:
          value: default
        podName:
          value: buttercup-app-.*
          useRegexp: true
        containerName:
          value: server
        firstEntryRegex: ^[^\s].*

Use https://regex101.com/ to find a golang regex that works for your format and specify it in the config file for the config option firstEntryRegex.

Collect journald events

Splunk OpenTelemetry Collector for Kubernetes can collect journald events from kubernetes environment. Process journald events by configuring logsCollection.journald section in values.yaml.

logsCollection:
  journald:
    enabled: true
    directory: /run/log/journal
    # List of service units to collect and configuration for each. Please update the list as needed.
    units:
      - name: kubelet
        priority: info
      - name: docker
        priority: info
      - name: containerd
        priority: info
    # Route journald logs to its own Splunk Index by specifying the index value below, else leave it blank. Please make sure the index exist in Splunk and is configured to receive HEC traffic (Not applicable to Splunk Observability).
    index: ""

Managing Log Ingestion by Using Annotations

Manage Splunk OTel Collector Logging with these supported annotations.

Use splunk.com/index annotation on pod and/or namespace to tell which Splunk platform indexes to ingest to. Pod annotation will take precedence over namespace annotation when both are annotated. For example, the following command will make logs from kube-system namespace to be sent to k8s_events index: kubectl annotate namespace kube-system splunk.com/index=k8s_events
Filter logs using pod and/or namespace annotation
- If logsCollection.containers.useSplunkIncludeAnnotation is false (default: false), set splunk.com/exclude annotation to true on pod and/or namespace to exclude its logs from ingested.
- If logsCollection.containers.useSplunkIncludeAnnotation is true (default: false), set splunk.com/include annotation to true on pod and/or namespace to only include its logs from ingested. All other logs will be ignored.
Use splunk.com/sourcetype annotation on pod to overwrite sourcetype field. If not set, it is dynamically generated to be kube:container:CONTAINER_NAME.

Performance of native OpenTelemetry logs collection

Some configurations used with the OpenTelemetry Collector (as set using the Splunk OpenTelemetry Collector for Kubernetes helm chart) can have an impact on overall performance of log ingestion. The more receivers, processors, exporters, and extensions that are added to any of the pipelines, the greater the performance impact.

Splunk OpenTelemetry Collector for Kubernetes can exceed the default throughput of the The HTTP Event Collector (HEC). To best address capacity needs, monitor the HEC throughput and back pressure on Splunk OpenTelemetry Collector for Kubernetes deployments and be prepared to add additional nodes as needed.

Here is the summary of performance benchmarks run internally.

Log Generator Count	Event Size (byte)	Agent CPU Usage	Agent EPS
1	256	1.8	30,000
1	516	1.8	28,000
1	1024	1.8	24,000
5	256	3.2	54,000
7	256	3	52,000
10	256	3.2	53,000

The data pipelines for these test runs involved reading container logs as they are being written, then parsing filename for metadata, enriching it with kubernetes metadata, reformatting data structure, and sending them (without compression) to Splunk HEC endpoint.

Running the container in non-root user mode

Collecting logs often requires reading log files that are owned by the root user. By default, the container runs with securityContext.runAsUser = 0 which gives the root user permission to read those files. To run the container in non-root user mode, set .agent.securityContext to 20000 to cause the container to run the required file system operations as UID and GID 20000. (it can be any other UID & GUI)

Note: cri-o container runtime did not work during internal testing.

Network explorer

Network explorer allows you to collect network telemetry for ingest and analysis. This telemetry is sent to the Open Telemetry Collector Gateway. To enable the network explorer, set the enabled flag to true

networkExplorer:
  enabled: true

Note: Enabling network explorer will automatically enable the Open Telemetry Collector Gateway.

Prerequisites

Network Explorer is only supported in Kubernetes-based environments on Linux hosts: RedHat Linux 7.6+, Ubuntu 16.04+, Debian Stretch+, Amazon Linux 2, Google COS.

Modifying the reducer footprint

The reducer is a single pod per Kubernetes cluster. If your cluster contains a large number of pods, nodes, and services, you can increase the resources allocated to it.

The reducer processes telemetry in multiple stages, with each stage partitioned into one or more shards, where each shard is a separate thread. Increasing the number of shards in each stage expands the capacity of the reducer. There are three stages: ingest, matching, and aggregation. You can set between 1-32 shards for each stage. There is 1 shard per reducer stage by default.

The following example sets the reducer to use 4 shards per stage.

networkExplorer:
  reducer:
    ingestShards: 4
    matchingShards: 4
    aggregationShards: 4

Customize network telemetry generated by Network Explorer

Metrics can be disabled, either singly or entire categories. See the values.yaml for a complete list of categories and metrics.

To disable an entire category, give the category name, followed by .all.

networkExplorer:
  reducer:
    disableMetrics:
      - tcp.all

Individual metrics can be disabled by their names.

networkExplorer:
  reducer:
    disableMetrics:
      - tcp.bytes

You can mix categories and names. For example, this will disable all http metrics and the udp.bytes metric.

networkExplorer:
  reducer:
    disableMetrics:
      - http.all
      - udp.bytes

enableMetrics allow you to turn back on metrics that were previously disabled.

Note: The disableMetrics flag is evaluated before the enableMetrics flag. This allows you to disable an entire category, then re-enable the individual metrics in that category that you are interested in.

This example disables all internal and http metrics but re-enables the ebpf_net.collector_health metric.

networkExplorer:
  reducer:
    disableMetrics:
    - http.all
    - ebpf_net.all

    enableMetrics:
    - ebpf_net.collector_health

Additional telemetry sources

Use autodetect config option to enable additional telemetry sources.

Set autodetect.prometheus=true if you want the otel-collector agent to scrape prometheus metrics from pods that have generic prometheus-style annotations:

prometheus.io/scrape: true: Prometheus metrics will be scraped only from pods having this annotation;
prometheus.io/path: path to scrape the metrics from, default /metrics;
prometheus.io/port: port to scrape the metrics from, default 9090.

Set autodetect.istio=true, if the otel-collector agent in running in Istio environment, to make sure that all traces, metrics and logs reported by Istio collected in a unified manner.

For example to enable both Prometheus and Istio telemetry add the following lines to your values.yaml file:

autodetect:
  istio: true
  prometheus: true

Using feature gates

Enable or disable features of the otel-collector agent, clusterReceiver, and gateway (respectively) using feature gates. Use the agent.featureGates, clusterReceiver.featureGates, and gateway.featureGates configs to enable or disable features, these configs will be used to populate the otelcol binary startup argument "--feature-gates". For more details see the feature gate documentation.

Helm Install Example:

helm install {name} --set agent.featureGates=+feature1 --set clusterReceiver.featureGates=feature2 --set gateway.featureGates=-feature2 {other_flags}

Would result in the agent having feature1 enabled, the clusterReceiver having feature2 enabled, and the gateway having feature2 disabled.

Override underlying OpenTelemetry agent configuration

If you want to use your own OpenTelemetry Agent configuration, you can override it by providing a custom configuration in the agent.config parameter in the values.yaml, which will be merged into the default agent configuration, list parts of the configuration (for example, service.pipelines.logs.processors) to be fully re-defined.

Manually setting Pod Security Policy

Support of Pod Security Policies (PSP) was removed in Kubernetes 1.25. If you still rely on PSPs in an older cluster, you can add them manually along with the helm chart installation.

Run the following command to install the PSP (don't forget to add --namespace kubectl argument if needed):

cat <<EOF | kubectl apply -f -
apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
  name: splunk-otel-collector-psp
  labels:
    app: splunk-otel-collector-psp
  annotations:
    seccomp.security.alpha.kubernetes.io/allowedProfileNames: 'runtime/default'
    apparmor.security.beta.kubernetes.io/allowedProfileNames: 'runtime/default'
    seccomp.security.alpha.kubernetes.io/defaultProfileName:  'runtime/default'
    apparmor.security.beta.kubernetes.io/defaultProfileName:  'runtime/default'
spec:
  privileged: false
  allowPrivilegeEscalation: false
  hostNetwork: true
  hostIPC: false
  hostPID: false
  volumes:
  - 'configMap'
  - 'emptyDir'
  - 'hostPath'
  - 'secret'
  runAsUser:
    rule: 'RunAsAny'
  seLinux:
    rule: 'RunAsAny'
  supplementalGroups:
    rule: 'RunAsAny'
  fsGroup:
    rule: 'RunAsAny'
EOF

Add the following custom ClusterRole rule in your values.yaml file along with all other required fields like clusterName, splunkObservability or splunkPlatform:

rbac:
  customRules:
    - apiGroups:     [extensions]
      resources:     [podsecuritypolicies]
      verbs:         [use]
      resourceNames: [splunk-otel-collector-psp]

Install the helm chart (assuming your custom values.yaml is called my_values.yaml):

helm install my-splunk-otel-collector -f my_values.yaml splunk-otel-collector-chart/splunk-otel-collector
