# Zabbix Kubernetes Discovery

[![Artifact Hub](https://img.shields.io/endpoint?url=https://artifacthub.io/badge/repository/djerfy&style=flat-square)](https://artifacthub.io/packages/search?repo=djerfy)

## Introduction

Kubernetes monitoring for Zabbix with discovery objects:

* Nodes

* DaemonSets

* Deployments

* StatefulSets

* Cronjobs

* PersistentVolumeClaims

Works with 2 variables only by default:

* `ZABBIX_ENDPOINT`: Zabbix server/proxy where the datas will be sent

* `KUBERNETES_NAME`: Name of your Kubernetes cluster on Zabbix (host)

## Helm

Before installation, you need to create `zabbix-monitoring` namespace in your cluster:

```bash

$ kubectl create namespace zabbix-monitoring

```

All Helm options/parameters are available in the [Helm folder here](./helm/).

### Install from local

To install the chart with the release name `zabbix-kubernetes-discovery` from local Helm templates:

```bash

$ helm upgrade --install zabbix-kubernetes-discovery \

    ./helm/zabbix-kubernetes-discovery/ \

    --values ./helm/zabbix-kubernetes-discovery/values.yaml \

    --namespace zabbix-monitoring \

    --set namespace.name="zabbix-monitoring" \

    --set environment.ZABBIX_ENDPOINT="zabbix-proxy.example.com" \

    --set environment.KUBERNETES_NAME="kubernetes-cluster-example"

```

### Install from repo

To install the chart with the release name `zabbix-kubernetes-discovery` from my Helm repository:

```bash

$ helm repo add djerfy https://djerfy.github.io/helm-charts

$ helm upgrade --install zabbix-kubernetes-discovery \

    djerfy/zabbix-kubernetes-discovery \

    --namespace zabbix-monitoring

    --set namespace.name="zabbix-monitoring" \

    --set environment.ZABBIX_ENDPOINT="zabbix-proxy.example.com" \

    --set environment.KUBERNETES_NAME="kubernetes-cluster-name"

```

### Uninstall

To uninstall/delete the `zabbix-kubernetes-discovery` deployment:

```bash

$ helm list -n zabbix-monitoring

$ helm delete -n zabbix-monitoring zabbix-kubernetes-discovery

```

The command removes all the Kubernetes components associated with the chart and deletes the release.

## Commands

```

usage: zabbix-kubernetes-discovery.py [-h]

    [--zabbix-timeout ZABBIX_TIMEOUT]

    --zabbix-endpoint ZABBIX_ENDPOINT

    --kubernetes-name KUBERNETES_NAME

    --monitoring-mode {volume,deployment,daemonset,node,statefulset,cronjob}

    --monitoring-type {discovery,item,json}

    [--object-name OBJECT_NAME]

    [--match-label KEY=VALUE]

    [--exclude-name EXCLUDE_NAME]

    [--exclude-namespace EXCLUDE_NAMESPACE]

    [--no-wait]

    [--verbose]

    [--debug]

```
