# Ceph by Zabbix agent 2

## Overview

For Zabbix version: 6.0 and higher  
The template to monitor Ceph cluster by Zabbix that work without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template `Ceph by Zabbix agent 2` — collects metrics by polling zabbix-agent2.



This template was tested on:

- Ceph, version 14.2

## Setup

> See [Zabbix template operation](https://www.zabbix.com/documentation/6.0/manual/config/templates_out_of_the_box/zabbix_agent2) for basic instructions.

1. Setup and configure zabbix-agent2 compiled with the Ceph monitoring plugin.
2. Set the {$CEPH.CONNSTRING} such as <protocol(host:port)> or named session.
3. Set the user name and password in host macros ({$CEPH.USER}, {$CEPH.API.KEY}) if you want to override parameters from the Zabbix agent configuration file.

Test availability: `zabbix_get -s ceph-host -k ceph.ping["{$CEPH.CONNSTRING}","{$CEPH.USER}","{$CEPH.API.KEY}"]`


## Zabbix configuration

No specific Zabbix configuration is required.
