Chart Values

The HIGGS Scanner ships as a Helm chart (wallarm/aih-scanner, current version 2.1.1). The tables below cover the values most customers tune. Everything else in the chart's values.yaml has a default that rarely needs overriding.

For pod and namespace labels that control which workloads the scanner observes, see Labels and Annotations.

Required values

Key Description
config.backendUrl URL of the AI Hypervisor backend (your tenant). Provided in the install commands on your tenant's empty-state screen.
scannerPrivateKey HMAC private key the scanner uses to authenticate to the backend. Provided alongside backendUrl. Mutually exclusive with existingSecret.name.
existingSecret.name Name of a pre-existing Kubernetes Secret in the scanner namespace that holds the private key. Use instead of scannerPrivateKey when you manage secrets externally (External Secrets Operator, sealed secrets, and so on).

Capture

Key Default Description
config.scanAllPods false When false, the scanner observes only pods that opted in via the labels described in Labels and Annotations. When true, the scanner observes every pod on the node (anti-loop exclusions still apply). Use true for short-lived investigations only. Opt-in is the production pattern.
config.continuousScanEnabled false When true, the scanner re-scans labeled pods continuously. When false, it scans once per pod lifecycle event.

Image and namespace

Key Default Description
image.tag matches chart version (currently 2.1.1) Override only to pin a specific scanner version.
image.pullPolicy IfNotPresent Standard image-pull semantics.
imagePullSecretData (empty) Base64-encoded .dockerconfigjson for the scanner pull secret. When set, the chart creates the secret automatically. Use when pulling from a private mirror.
namespace.name higgs-system The namespace the scanner runs in. Change when higgs-system collides with an existing resource.
namespace.create true Set to false if the namespace already exists and you do not want Helm to take ownership.

Resource limits and lifecycle

Key Default Description
resources.requests.cpu 200m Per-scanner-pod CPU request.
resources.limits.cpu 2 Per-scanner-pod CPU limit. Under burst load (50+ concurrent users with full DNAT) the scanner can reach ~950m; the limit gives headroom.
resources.requests.memory 512Mi Per-scanner-pod memory request.
resources.limits.memory 1536Mi Per-scanner-pod memory limit.
terminationGracePeriodSeconds 75 Must exceed config.uploadTimeoutSeconds so in-flight uploads complete during graceful shutdown.
priorityClassName system-node-critical Ensures the scanner is not evicted under node pressure.

Disk and retention

Key Default Description
config.maxDumpFiles 50 Maximum scan dumps kept on disk per node before pruning.
config.maxDumpAgeHours 12 Maximum age before a dump is pruned.
config.maxDumpSizeMb 200 Maximum total dump size per node.
scanOutputSizeLimit 1Gi Hard limit on the scanner's emptyDir volume.

Optional features

Key Default Description
agents.enabled true Enables in-process language agents. Required for accurate user attribution on multi-hop calls.
prometheus.enabled false Adds Prometheus scrape annotations to the scanner pod for metrics collection.
networkPolicy.enabled false Creates a NetworkPolicy restricting scanner egress to the backend URL only.

Inspecting current configuration

To see what values your existing install was deployed with:

helm get values aih-scanner -n higgs-system

To see the rendered manifests:

helm get manifest aih-scanner -n higgs-system

Updating configuration

To change Helm values, re-run helm upgrade:

helm upgrade aih-scanner wallarm/aih-scanner \
  --namespace higgs-system \
  --version 2.1.1 \
  --reuse-values \
  --set <KEY>=<NEW_VALUE>

The DaemonSet rolls out one node at a time. Scanner restarts do not interrupt observation; events buffer in memory until the new scanner attaches.
