# prometheus-rabbitmq-exporter
|
||||
|
||||
[rabbitmq_exporter](https://github.com/kbudde/rabbitmq_exporter) is a Prometheus exporter for rabbitmq metrics.
|
||||
|
||||
## TL;DR;
|
||||
|
||||
```bash
|
||||
$ helm install stable/prometheus-rabbitmq-exporter
|
||||
```
|
||||
|
||||
## Introduction
|
||||
|
||||
This chart bootstraps a [rabbitmq_exporter](https://github.com/kbudde/rabbitmq_exporter) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.8+ with Beta APIs enabled
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release stable/prometheus-rabbitmq-exporter
|
||||
```
|
||||
|
||||
The command deploys prometheus-rabbitmq-exporter on the Kubernetes cluster in the default configuration.
|
||||
|
||||
## 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 tables lists the configurable parameters and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------ | ---------------------------------------------------------------------- | ------------------------- |
|
||||
| `replicaCount` | desired number of prometheus-rabbitmq-exporter pods | `1` |
|
||||
| `image.repository` | prometheus-rabbitmq-exporter image repository | `kbudde/rabbitmq-exporter`|
|
||||
| `image.tag` | prometheus-rabbitmq-exporter image tag | `v0.28.0` |
|
||||
| `image.pullPolicy` | image pull policy | `IfNotPresent` |
|
||||
| `service.type` | desired service type | `ClusterIP` |
|
||||
| `service.internalport` | service listening port | `9121` |
|
||||
| `service.externalPort` | public service port | `9419` |
|
||||
| `resources` | cpu/memory resource requests/limits | {} |
|
||||
| `loglevel` | exporter log level | {} |
|
||||
| `rabbitmq.url` | rabbitm managment url | `http://myrabbit:15672` |
|
||||
| `rabbitmq.user` | rabbitm user login | `guest` |
|
||||
| `rabbitmq.password` | rabbitm password login | `guest` |
|
||||
| `rabbitmq.capabilities` | comma-separated list of capabilities supported by the RabbitMQ server | `bert,no_sort` |
|
||||
| `rabbitmq.include_queues`| regex queue filter. just matching names are exported | `.*` |
|
||||
| `rabbitmq.skip_queues` | regex, matching queue names are not exported | `.*` |
|
||||
| `annotation` | pod annotations for easier discovery | {} |
|
||||
|
||||
For more information please refer to the [rabbitmq_exporter](https://github.com/kbudde/rabbitmq_exporter) documentation.
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release \
|
||||
--set "rabbitmq.url=http://myrabbit:15672" \
|
||||
stable/prometheus-rabbitmq-exporter
|
||||
```
|
||||
|
||||
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/prometheus-rabbitmq-exporter
|
||||
```
