# Metricbeat
|
||||
|
||||
[metricbeat](https://www.elastic.co/guide/en/beats/metricbeat/current/index.html) is used to ship Kubernetes and host metrics to multiple outputs.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.9+
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release stable/metricbeat
|
||||
```
|
||||
|
||||
> **Tip**: List all releases using `helm list`
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
To uninstall/delete the `my-release` deployment:
|
||||
|
||||
```bash
|
||||
$ helm delete my-release
|
||||
```
|
||||
|
||||
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||
|
||||
## Configuration
|
||||
|
||||
The following table lists the configurable parameters of the metricbeat chart and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
|-------------------------------------|------------------------------------|-------------------------------------------|
|
||||
| `image.repository` | The image repository to pull from | `docker.elastic.co/beats/metricbeat` |
|
||||
| `image.tag` | The image tag to pull | `6.4.0` |
|
||||
| `image.pullPolicy` | Image pull policy | `IfNotPresent` |
|
||||
| `rbac.create` | If true, create & use RBAC resources | `true` |
|
||||
| `serviceAccount.create` | If true, create & use ServiceAccount | `true` |
|
||||
| `serviceAccount.name` | The name of the ServiceAccount to use. If not set and create is true, a name is generated using the fullname template | |
|
||||
| `config` | The content of the configuration file consumed by metricbeat. See the [metricbeat.reference.yml](https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-reference-yml.html) for full details | |
|
||||
| `plugins` | List of beat plugins | |
|
||||
| `extraEnv` | Additional environment | |
|
||||
| `extraVolumes`, `extraVolumeMounts` | Additional volumes and mounts, for example to provide other configuration files | |
|
||||
| `resources.requests.cpu` | CPU resource requests | |
|
||||
| `resources.limits.cpu` | CPU resource limits | |
|
||||
| `resources.requests.memory` | Memory resource requests | |
|
||||
| `resources.limits.memory` | Memory resource limits | |
|
||||
| `daemonset.modules.<name>.config` | The content of the modules configuration file consumed by metricbeat deployed as daemonset, which is assumed to collect metrics in each nodes. See the [metricbeat.reference.yml](https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-reference-yml.html) for full details |
|
||||
| `daemonset.modules.<name>.enabled` | If true, enable configuration | |
|
||||
| `daemonset.podAnnotations` | Pod annotations for daemonset | |
|
||||
| `deployment.modules.<name>.config` | The content of the modules configuration file consumed by metricbeat deployed as deployment, which is assumed to collect cluster-level metrics. See the [metricbeat.reference.yml](https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-reference-yml.html) for full details ||
|
||||
| `deployment.modules.<name>.enabled` | If true, enable configuration ||
|
||||
| `deployment.podAnnotations` | Pod annotations for deployment | |
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release \
|
||||
--set rbac.create=true \
|
||||
stable/metricbeat
|
||||
```
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release -f values.yaml stable/metricbeat
|
||||
```
|
||||
|
||||
> **Tip**: You can use the default [values.yaml](values.yaml)
