# Kubernetes cluster state by HTTP

## Overview

The template to monitor Kubernetes state that work without any external scripts. 
It works without external scripts and uses the script item to make HTTP requests to the Kubernetes API.

Template `Kubernetes cluster state by HTTP` - collects metrics by HTTP agent from kube-state-metrics endpoint and Kubernetes API.

Don't forget change macros {$KUBE.API.URL} and {$KUBE.API.TOKEN}.
Also, see the Macros section for a list of macros used to set trigger values.

*NOTE.* Some metrics may not be collected depending on your Kubernetes version and configuration.

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- Kubernetes 1.19.10

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.

## Setup

Install the [Zabbix Helm Chart](https://git.zabbix.com/projects/ZT/repos/kubernetes-helm/browse?at=refs%2Fheads%2Frelease%2F7.0) in your Kubernetes cluster.
Internal service metrics are collected from kube-state-metrics endpoint.

Template needs to use Authorization via API token.

Set the `{$KUBE.API.URL}` such as `<scheme>://<host>:<port>`.

Get the generated service account token using the command:

`kubectl get secret zabbix-service-account -n monitoring -o jsonpath={.data.token} | base64 -d`

Then set it to the macro `{$KUBE.API.TOKEN}`.  
Set `{$KUBE.STATE.ENDPOINT.NAME}` with Kube state metrics endpoint name. See `kubectl -n monitoring get ep`. Default: `zabbix-kube-state-metrics`.

*NOTE.* If you wish to monitor Controller Manager and Scheduler components, you might need to set the `--binding-address` option for them to the address where Zabbix proxy can reach them.
For example, for clusters created with `kubeadm` it can be set in the following manifest files (changes will be applied immediately):

- /etc/kubernetes/manifests/kube-controller-manager.yaml
- /etc/kubernetes/manifests/kube-scheduler.yaml

Depending on your Kubernetes distribution, you might need to adjust `{$KUBE.CONTROL_PLANE.TAINT}` macro (for example, set it to `node-role.kubernetes.io/master` for OpenShift).

*NOTE.* Some metrics may not be collected depending on your Kubernetes version and configuration.

Also, see the Macros section for a list of macros used to set trigger values.

Set up the macros to filter the metrics of discovered Kubelets by node names:

- {$KUBE.LLD.FILTER.KUBELET_NODE.MATCHES}
- {$KUBE.LLD.FILTER.KUBELET_NODE.NOT_MATCHES}

Set up macros to filter metrics by namespace:

- {$KUBE.LLD.FILTER.NAMESPACE.MATCHES}
- {$KUBE.LLD.FILTER.NAMESPACE.NOT_MATCHES}

Set up macros to filter node metrics by nodename:

- {$KUBE.LLD.FILTER.NODE.MATCHES}
- {$KUBE.LLD.FILTER.NODE.NOT_MATCHES}

**Note**, If you have a large cluster, it is highly recommended to set a filter for discoverable namespaces.

You can use the `{$KUBE.KUBELET.FILTER.LABELS}` and `{$KUBE.KUBELET.FILTER.ANNOTATIONS}` macros for advanced filtering of Kubelets by node labels and annotations.

Notes about labels and annotations filters:

- Macro values should be specified separated by commas and must have the key/value form with support for regular expressions in the value (`key1: value, key2: regexp`).
- ECMAScript syntax is used for regular expressions.
- Filters are applied if such a label key exists for the entity that is being filtered (it means that if you specify a key in a filter, entities which do not have this key will not be affected by the filter and will still be discovered, and only entities containing that key will be filtered by the value).
- You can also use the exclamation point symbol (`!`) to invert the filter (`!key: value`).

For example: `kubernetes.io/hostname: kubernetes-node[5-25], !node-role.kubernetes.io/ingress: .*`. As a result, the Kubelets on nodes 5-25 without the "ingress" role will be discovered.


See the Kubernetes documentation for details about labels and annotations:

- <https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/>
- <https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/>

You can also set up evaluation periods for replica mismatch triggers (Deployments, ReplicaSets, StatefulSets) with the macro `{$KUBE.REPLICA.MISMATCH.EVAL_PERIOD}`, which supports context and regular expressions. For example, you can create the following macros:

- Set the evaluation period for the Deployment "nginx-deployment" in the namespace "default" to the 3 last values:

`{$KUBE.REPLICA.MISMATCH.EVAL_PERIOD:"deployment:default:nginx-deployment"} = #3`

- Set the evaluation period for all Deployments to the 10 last values:

`{$KUBE.REPLICA.MISMATCH.EVAL_PERIOD:regex:"deployment:.*:.*"} = #10` or `{$KUBE.REPLICA.MISMATCH.EVAL_PERIOD:regex:"^deployment.*"} = #10`

- Set the evaluation period for Deployments, ReplicaSets and StatefulSets in the namespace "default" to 15 minutes:

`{$KUBE.REPLICA.MISMATCH.EVAL_PERIOD:regex:".*:default:.*"} = 15m`

**Note**, that different context macros with regular expressions matching the same string can be applied in an undefined order and simple context macros (without regular expressions) have higher priority. Read the **Important notes** section in [`Zabbix documentation`](https://www.zabbix.com/documentation/7.0/manual/config/macros/user_macros_context) for details.
