Grafana 是纯Javascript开发的前端展示工具。后端数据源可以通过Graphite、InfluxDB、OpenTsDB等获取数据，或者通过插件的方式获取zabbix监控的数据。然后在前端通过Grafana展示数据，grafana可以自定义各种图表。

以上设定，调试完善后， 可将dashboard导出另存。
5. 可导入的dashboard json文件，快速完成 Dashboard 定义
6. 默认的Grafans服务端口是3000，可修改/etc/grafana/grafana.ini 文件内的 http_port，由3000到80。
因为Linux对非系统进程限制了使用1024以下端口， 对于2.6.24及更新的Kerner Linux，可运行下面命令，完成授权(give the Grafana binary permission)：
# setcap 'cap_net_bind_service+ep' /usr/sbin/grafana-server
7. LDAP for Grafana 认证设定
- 官方文档： http://docs.grafana.org/installation/ldap/
- 下面仅涉及到修改过的参数；未提及内容保持默认设定
- Grafana 中的权限设定，有3种，分别是admin, editor, viewer。 作为对应， AD中分别新增3个域群组； 不同的域账号，依据权限分配，加到不同群组里，实现grafana登录授权。
- Grafana web UI里面，对于域账号的以上3种权限虽然可修改，但该最终权限，以域账号所属域群组为准，账号每次重新登录，会覆盖Web UI内的设定。
In [[servers.group_mappings]] you can map an LDAP group to a Grafana organization and role. These will be synced every time the user logs in, with LDAP being the authoritative source. So, if you change a user’s role in the Grafana Org. Users page, this change will be reset the next time the user logs in. If you change the LDAP groups of a user, the change will take effect the next time the user logs in.
7.1 修改grafana.ini文件，开启ldap认证功能。
Internet上的设定文件是 /usr/share/grafana/conf/defaults.ini， 但该设定文件中的ldap设定项，已经不适用于 Grafana v5.x版本。
v5.x版本中，开启ldap设定的配置文件、及设定项是：
/etc/grafana/grafana.ini
[auth.ldap]
enabled = true
config_file = /etc/grafana/ldap.toml
allow_sign_up = true
7.2 定义ldap各参数
/etc/grafana/ldap.toml
[[servers]]
host = "10.245.4.167 10.245.5.168"
bind_dn = "CN=zabbixCQ2,OU=CQ,OU=ServicesUsers,OU=ECMMSUsers,DC=ECMMS,DC=ORG"
bind_password = 'ORG123'
search_filter = "(sAMAccountName=%s)"
search_base_dns = ["OU=ECMMSUsers,DC=ECMMS,DC=ORG"]
[servers.attributes]
username = "sAMAccountName"
[[servers.group_mappings]]
group_dn = "CN=zabbixCQ-Grafana-A,OU=CQ,OU=ServicesUsers,OU=ECMMSUsers,DC=ECMMS,DC=ORG"
org_role = "Admin"
[[servers.group_mappings]]
group_dn = "CN=zabbixCQ-Grafana-E,OU=CQ,OU=ServicesUsers,OU=ECMMSUsers,DC=ECMMS,DC=ORG"
org_role = "Editor"
[[servers.group_mappings]]
group_dn = "CN=zabbixCQ-Grafana-V,OU=CQ,OU=ServicesUsers,OU=ECMMSUsers,DC=ECMMS,DC=ORG"
org_role = "Viewer"
