Module: job-node_exporter
Description: Scrapes node_exporter
Note: Every argument except for "forward_to" is optional, and does have a defined default value. However, the values for these
arguments are not defined using the default = " ... " argument syntax, but rather using the coalesce(argument.value, " ... ").
This is because if the argument passed in from another consuming module is set to null, the default = " ... " syntax will
does not override the value passed in, where coalesce() will return the first non-null value.

# Grafana Alloy Helm chart
![Type: application](https://img.shields.io/badge/Type-application-informational?style=flat-square) ![Version: 0.11.0](https://img.shields.io/badge/Version-0.11.0-informational?style=flat-square) ![AppVersion: v1.6.1](https://img.shields.io/badge/AppVersion-v1.6.1-informational?style=flat-square)
Helm chart for deploying [Grafana Alloy][] to Kubernetes.
[Grafana Alloy]: https://grafana.com/docs/alloy/latest/
## Usage
### Setup Grafana chart repository
```
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
```
### Install chart
To install the chart with the release name my-release:
`helm install my-release grafana/alloy`
This chart installs one instance of Grafana Alloy into your Kubernetes cluster
using a specific Kubernetes controller. By default, DaemonSet is used. The
`controller.type` value can be used to change the controller to either a
StatefulSet or Deployment.
Creating multiple installations of the Helm chart with different controllers is
useful if just using the default DaemonSet isn't sufficient.

#### Migrate from `grafana/grafana-agent` chart to `grafana/alloy`
The `values.yaml` file for the `grafana/grafana-agent` chart is compatible with
the chart for `grafana/alloy`, with two exceptions:
* The `agent` field in `values.yaml` is deprecated in favor of `alloy`. Support
for the `agent` field will be removed in a future release.
* The default value for `alloy.listenPort` is `12345` to align with the default
listen port in other installations. To retain the previous default, set
`alloy.listenPort` to `80` when installing.
### alloy.stabilityLevel
`alloy.stabilityLevel` controls the minimum level of stability for what
components can be created (directly or through imported modules). Note that
setting this field to a lower stability may also enable internal behaviour of a
lower stability, such as experimental memory optimizations.
Valid settings are `experimental`, `public-preview`, and `generally-available`.
### alloy.extraArgs
`alloy.extraArgs` allows for passing extra arguments to the Grafana Alloy
container. The list of available arguments is documented on [alloy run][].
> **WARNING**: Using `alloy.extraArgs` does not have a stable API. Things may
> break between Chart upgrade if an argument gets added to the template.
[alloy run]: https://grafana.com/docs/alloy/latest/reference/cli/run/
### alloy.extraPorts
`alloy.extraPorts` allows for configuring specific open ports.
The detained specification of ports can be found at the [Kubernetes Pod documents](https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/pod-v1/#ports).
Port numbers specified must be 0 < x < 65535.
| ChartPort | KubePort | Description |
|-----------|----------|-------------|
| targetPort | containerPort | Number of port to expose on the pod's IP address. |
| hostPort | hostPort | (Optional) Number of port to expose on the host. Daemonsets taking traffic might find this useful. |
| name | name | If specified, this must be an `IANA_SVC_NAME` and unique within the pod. Each named port in a pod must have a unique name. Name for the port that can be referred to by services.
| protocol | protocol | Must be UDP, TCP, or SCTP. Defaults to "TCP". |
| appProtocol | appProtocol | Hint on application protocol. This is used to expose Alloy externally on OpenShift clusters using "h2c". Optional. No default value. |
### alloy.listenAddr
`alloy.listenAddr` allows for restricting which address Alloy listens on
for network traffic on its HTTP server. By default, this is `0.0.0.0` to allow
its UI to be exposed when port-forwarding and to expose its metrics to other
Alloy instances in the cluster.
### alloy.configMap.config
`alloy.configMap.content` holds the Grafana Alloy configuration to use.
If `alloy.configMap.content` is not provided, a [default configuration file][default-config] is
used. When provided, `alloy.configMap.content` must hold a valid Alloy configuration file.
[default-config]: ./config/example.alloy
### alloy.securityContext
`alloy.securityContext` sets the securityContext passed to the Grafana
Alloy container.
By default, Grafana Alloy containers are not able to collect telemetry from the
host node or other specific types of privileged telemetry data. See [Collecting
logs from other containers][#collecting-logs-from-other-containers] and
[Collecting host node telemetry][#collecting-host-node-telemetry] below for
more information on how to enable these capabilities.
### rbac.create
`rbac.create` enables the creation of ClusterRole and ClusterRoleBindings for
the Grafana Alloy containers to use. The default permission set allows
components like [discovery.kubernetes][] to work properly.
[discovery.kubernetes]: https://grafana.com/docs/alloy/latest/reference/components/discovery.kubernetes/
### controller.autoscaling
`controller.autoscaling.enabled` enables the creation of a HorizontalPodAutoscaler. It is only used when `controller.type` is set to `deployment` or `statefulset`.
`controller.autoscaling` is intended to be used with [clustered][] mode.
> **WARNING**: Using `controller.autoscaling` for any other Grafana Alloy
> configuration could lead to redundant or double telemetry collection.
[clustered]: https://grafana.com/docs/alloy/latest/reference/cli/run/#clustered-mode
When using autoscaling with a StatefulSet controller and have enabled
volumeClaimTemplates to be created alongside the StatefulSet, it is possible to
leak up to `maxReplicas` PVCs when the HPA is scaling down. If you're on
Kubernetes version `>=1.23-0` and your cluster has the
`StatefulSetAutoDeletePVC` feature gate enabled, you can set
`enableStatefulSetAutoDeletePVC` to true to automatically delete stale PVCs.
Using `controller.autoscaling` requires the target metric (cpu/memory) to have
its resource requests set up for both the Alloy and config-reloader containers
so that the HPA can use them to calculate the replica count from the actual
resource utilization.
## Collecting logs from other containers
There are two ways to collect logs from other containers within the cluster
Alloy is deployed in.
### loki.source.kubernetes
The [loki.source.kubernetes][] component may be used to collect logs from
containers using the Kubernetes API. This component does not require mounting
the hosts filesystem into Alloy, nor requires additional security contexts to
work correctly.
[loki.source.kubernetes]: https://grafana.com/docs/alloy/latest/reference/components/loki.source.kubernetes/
### File-based collection
Logs may also be collected by mounting the host's filesystem into the Alloy
container, bypassing the need to communicate with the Kubrnetes API.
To mount logs from other containers to Grafana Alloy directly:
* Set `alloy.mounts.dockercontainers` to `true`.
* Set `alloy.securityContext` to:
```yaml
privileged: true
runAsUser: 0
```
## Collecting host node telemetry
Telemetry from the host, such as host-specific log files (from `/var/logs`) or
metrics from `/proc` and `/sys` are not accessible to Grafana Alloy containers.
To expose this information to Grafana Alloy for telemetry collection:
* Set `alloy.mounts.dockercontainers` to `true`.
* Mount `/proc` and `/sys` from the host into the container.
* Set `alloy.securityContext` to:
```yaml
privileged: true
runAsUser: 0
```
## Expose Alloy externally on OpenShift clusters
If you want to send telemetry from an Alloy instance outside of the OpenShift clusters over gRPC towards the Alloy instance on the OpenShift clusters, you need to:
* Set the optional `appProtocol` on `alloy.extraPorts` to `h2c`
* Expose the service via Ingress or Route within the OpenShift cluster. Example of a Route in OpenShift:
```yaml
kind: Route
apiVersion: route.openshift.io/v1
metadata:
name: route-otlp-alloy-h2c
spec:
to:
kind: Service
name: test-grpc-h2c
weight: 100
port:
targetPort: otlp-grpc
tls:
termination: edge
insecureEdgeTerminationPolicy: Redirect
wildcardPolicy: None
```
Once this Ingress/Route is exposed it would then allow gRPC communication for (for example) traces. This allow an Alloy instance on a VM or another Kubernetes/OpenShift cluster to be able to communicate over gRPC via the exposed Ingress or Route.
