Grafana dashboard: Ceph Cluster
Description: Ceph cluster dashborad (Monitoring data is from ceph mgr zabbix plugin )

This dashboard is using ceph mgr zabbix plugins to generate monitoring data ,and using zabbix-grafana to fetch data from zabbix to grafana

### To enable ceph zabbix plugin,using command below
you can reference this [link1](http://ceph.com/community/new-luminous-zabbix/) and [link2](http://docs.ceph.com/docs/master/mgr/zabbix/)
``` bash
ceph mgr module zabbix enable
ceph zabbix config-set zabbix_host zabbix.lab.local
ceph zabbix config-set identifier ceph.lab.local
```
## In zabbix:
* import the template [here](https://github.com/ceph/ceph/blob/master/src/pybind/mgr/zabbix/zabbix_template.xml) and the source code folder is [here](https://github.com/ceph/ceph/blob/master/src/pybind/mgr/zabbix/)

* create a host named with ceph.lab.local( replace your own) ,add to ceph group and link the template "ceph-mgr Zabbix module"

### in grafana 
you can reference this [link](https://github.com/alexanderzobnin/grafana-zabbix)
* install the zabbix-grafana plugin and create datasource named zabbix
* import this dashborad
