我尝试使用grafana的api从模板创建grafana仪表板。我现在使用grafana v2.0.2。
我有一个api密钥,我可以使用curl获取仪表板,但我无法创建仪表板。
当我执行以下请求时:curl -i -H "Authorization: Bearer eyJrIobfuscatedlkIjoxfQ==" http://localhost:3000/api/dashboards/db/webserver2
然后我让json回到了dasboard。
当我尝试创建我在api示例中找到的最简单的仪表板时,它不起作用:curl -i -H "Authorization: Bearer eyJrIobfuscatedlkIjoxfQ==" -d /tmp/simpledash http://localhost:3000/api/dashboards/db
其中/tmp/simpledash
包含:
{
"dashboard": {
"id": null,
"title": "Production Overview",
"tags": [ "templated" ],
"timezone": "browser",
"rows": [
{
}
]
"schemaVersion": 6,
"version": 0
},
"overwrite": false
}
我收到以下回复:
HTTP/1.1 422 status code 422
Content-Type: application/json; charset=utf-8
Date: Wed, 01 Jul 2015 16:16:48 GMT
Content-Length: 84
[{"fieldNames": ["Dashboard"],"classification":"RequiredError","message":"Required"}]
我尝试了json的一些变体,但我总是得到那个响应,在互联网上我找不到一个有效的例子。有人为我做过一个有效的例子吗?我喜欢这个工作,所以我可以从ansible创建仪表板。
谢谢!

它失败的原因是API需要知道有效载荷是json。
使用cURL
curl -XPOST -i http://localhost:3000/api/dashboards/db --data-binary @./test.json -H "Content-Type: application/json"
与ansible
- name: postinstall::dashsetups
uri:
url: http://{{grafana.ip}}:{{grafana.bind}}/api/dashboards/db
method: POST
user: "{{ admin_usr }}"
password: "{{ admin_pwd }}"
body: "{{ lookup('template', item.file) }}"
status_code: 200
body_format: raw
force_basic_auth: yes
HEADER_Content-Type: "application/json"
with_items: "{{ grafana.dashboards }}"
和包含仪表板的vars文件
"grafana":{"dashboards": [
{
"name": "t1",
"file": "./dashboards/filename.json.j2",
"dash_name": "Test 1"
},
{
"name": "t2",
"file": "./dashboards/filename2.json.j2",
"dash_name": "Test 2"
},
{
"name": "t3",
"file": "./dashboards/template3.json.j2",
"dash_name": "Test 3"
}
]
}

我昨晚想到这个,网站上的例子在“schemaVersion”之前缺少一个逗号
正确的json应该是:
{
"dashboard": {
"id": null,
"title": "Production Overview",
"tags": [ "templated" ],
"timezone": "browser",
"rows": [
{
}
],
"schemaVersion": 6,
"version": 0
},
"overwrite": false
}
如果你将你的json复制到这个json验证器中,它会告诉你问题的确切位置:

要使用curl从文件发布数据,请在文件名之前放置@,如下所示:
curl -i -H "Authorization: Bearer eyJrIobfuscatedlkIjoxfQ==" -d @/tmp/simpledash http://localhost:3000/api/dashboards/db

我解决了这个问题:
1-首先创建这样的数据源(在我的情况下,我使用了collectd,prometheus和grafana的组合)
curl --user admin:admin 'http://IPADDR:3000/api/datasources' -X POST -H 'Content-Type: application/json;charset=UTF-8' --data-binary '{"name":"test","type":"prometheus","url":"http://localhost:9090","access":"proxy","basicAuth":false}'
2 - 要添加自定义的json仪表板,请编辑grafana.ini文件并启用Dashboard json文件部分,如下所示:
;##################### Dashboard JSON files #####################
[dashboards.json]
enabled = true
path = /var/lib/grafana/dashboards
3-然后将仪表板json文件复制到/ var / lib / grafana / dashboards(需要重启服务)

Userful ONE-LINER从您的计算机导入JSON仪表板
for i in `ls *.json` ;do curl -i -u GRAFANA_USERNAME:GRAFANA_PASSWORD -H "Content-Type: application/json" -X POST http://GRAFANA_HOST/api/dashboards/db -d @$i ; done
请从上面的命令更改GRAFANA_USERNAME,GRAFANA_PASSWORD和GRAFANA_HOST。

我正在添加一种使用python脚本的方式
import requests
url='http://admin:admin@localhost:3000/api/dashboards/db'
data='''{
"dashboard": {
"id": null,
"uid": "mahadev",
"title": "scriptedDashboard",
"tags": [ "templated" ],
"timezone": "browser",
"schemaVersion": 16,
"version": 0
},
"folderId": 48,
"overwrite": false
}'''
headers={"Content-Type": 'application/json'}
response = requests.post(url, data=data,headers=headers)
print (response.text)
