Vero Monitor Service

This probe is on the development roadmap.

Description

The k8s_mon probe monitors Kubernetes resources: Deployment, DaemonSet, StatefulSet (replicas), Pod (readiness, restarts), Node (readiness), and Service (existence). Optional CPU/memory via metrics-server. Build tag vms_heavy. Uses in-cluster config + ServiceAccount. Requires RBAC get/list on the target resource.

Config fields

Field	Type	Required	Default	Description
`type`	`string`	Yes	—	Must be `"k8s_mon"`
`namespace`	`string`	No	`"default"`	Kubernetes namespace
`workloadKind`	`string`	Yes	—	Resource kind: `"Node"`, `"Pod"`, `"Deployment"`, `"DaemonSet"`, `"StatefulSet"`, `"Service"`
`workloadName`	`string`	*	—	Specific resource name. One of `workloadName` or `labelSelector` required
`labelSelector`	`string`	*	—	Label selector (e.g. `"app=core-api"`)
`collectStats`	`bool`	No	`false`	Collect CPU/memory per pod via metrics-server

Metrics

Deployment / DaemonSet / StatefulSet

Metric	Type	Labels
`vms.k8s_mon.status`	status	`kind`, `namespace`, `workload`
`vms.k8s_mon.workload.available`	gauge	`kind`, `namespace`, `workload`
`vms.k8s_mon.workload.desired`	gauge	`kind`, `namespace`, `workload`

Pod

Metric	Type	Labels
`vms.k8s_mon.pod.ready`	gauge	`kind`, `namespace`, `pod`
`vms.k8s_mon.restart_count`	counter	`kind`, `namespace`, `pod`

Stats (collectStats = true)

Metric	Type	Unit	Labels
`vms.k8s_mon.cpu_millicores`	gauge	millicores	`kind`, `namespace`, `pod`
`vms.k8s_mon.memory_bytes`	gauge	bytes	`kind`, `namespace`, `pod`

Example config

{
  "type": "k8s_mon",
  "namespace": "core",
  "workloadKind": "Deployment",
  "workloadName": "core-api",
  "collectStats": true
}

Notes

Max 100 pods/nodes emitted per run.
Missing RBAC → unknown status with vms.agent.permission_missing{capability=kubernetes_rbac}.
collectStats requires metrics-server installed. If absent, stats are silently skipped.
Build tag vms_heavy — not in default agent package.
