【中文标题】“消息”:使用 HTTP API 导入 grafana 现有 json 文件时出现“无法导入仪表板”错误【英文标题】:"message":"Failed to import dashboard" error while import grafana existing json file using HTTP API 【发布时间】:2019-11-15 00:28:09 【问题描述】:我正在尝试使用 HTTP API 将现有 json 文件导入 grafana,它正在成功读取 json 文件,但对于每一行,它都会抛出 command not found
错误。
我尝试执行以下命令,
curl -X POST --insecure -H "Authorization: Bearer eyJrIjoiOWwwUmpQYUFmczhRVG1CZ1VmdTZ1VlZLTlc2ba0xUb0QiLCJuIjoia2xhIiwiaWQiOjJ9" -H "Content-Type: application/json" -d '"dashboard":"id": 1,"title": "tested33","tags": ["templated"],"timezone": "browser","rows": [],"schemaVersion": 6,"version": 0,"overwrite":false' -d "$(/u04/my_metrics.json)" localhost:3000/api/dashboards/db
它正在读取 json 文件中的每一行但抛出错误

请检查 json 文件一次并帮助我解决此问题
【问题讨论】:
将curl
更改为 curl -v
以获取详细输出并附加完整响应的 pastebin

我收到了上述消息
您可以查看任何服务器端日志吗?
【参考方案1】:
您正在尝试导入在 Grafana UI 中导出的仪表板 json /u04/my_metrics.json
。您还必须使用 Grafana UI 进行导入 - https://grafana.com/docs/reference/export_import/。
如果要使用 Grafana 仪表板 API (https://grafana.com/docs/http_api/dashboard/),则需要从 Grafana API 中“导出”(正确的 API 名称为“获取仪表板”)。
Grafana UI 和 Grafana 仪表板 API 生成不同的仪表板 JSON 正文架构,因此您无法轻松互换它们。理论上您可以将 json 转换为正确的格式,但您需要熟悉使用的仪表板 JSON 正文模式。
【讨论】:
感谢您提供信息,作为初学者,我在从 api 获取仪表板时遇到困难,在文档中,它提到我需要发送请求,例如 'GET /api/dashboards/uid/cIBgcSjkk HTTP / 1.1'如何为此形成curl请求以及上面命令中的'cIBgcSjkk'是什么,如果我是对的,我认为我需要形成类似'curl -X GET --insecure -H'的请求“授权:承载eyJrIjoiOWwwUmpQYUFmczhRVG1CZ1VmdTZ1VlZLTlc2ba0xUb0QiLCJuIjoia2xhIi '' 能否请您协助如何形成 curl 命令来获取仪表板 api 我终于找到了解决方案,我从这个链接github.com/hagen1778/grafana-import-export使用了API导出器并使用curl命令导入仪表板 curl -XPOST -i localhost:3000/api/dashboards/db -u username:password --data-binary @/jsonfilepath/my.json -H "Content-Type: application/json"【参考方案2】:请从 json 中删除 "id": 17。它将开始工作
【讨论】:
请解释为什么这样可以解决问题 这是使用我们正在做的API和创建时的后期操作。导入仪表板时,将在内部生成“id”。所以,我们不应该放它。【参考方案3】:我需要使用配置了必要仪表板的 grafana 自动启动 docker 容器,因此我按照以下步骤操作:
首先,我配置仪表板,在我的案例中使用存储在 Prometheus,仪表板设计完成后,我使用导出 显示仪表板的 UID 的选项(它也存在于 网址)。 接下来,我使用 Postman 工具并调用 Grafana REST API 来获取 通过其 UID 以 JSON 格式显示仪表板的详细信息。你可以获得更多 following link 中的信息。在我的例子中,我使用默认的用户名和密码(admin / admin)以及配置 Docker 容器时映射的端口 3000。
网址如下:
http://admin:admin@localhost:3000/api/dashboards/uid/lNCIQZdGk
如您所见,它以兼容的格式返回仪表板的元数据,以便通过 Grafana REST API 导入。
作为最后一步,有必要删除 JSON 的 “id”属性,以避免在导入时收到 404,然后继续使用该配置创建新仪表板,为其分配一个新身份证。
如您所见,删除该属性将创建一个新仪表板并为其分配 id 4。
使用类似于以下的 CURL 命令通过脚本自动创建仪表板会更合适:
curl --verbose -L -s --fail -H "Accept: application/json" -H "Content-Type: application/json" -X POST -k http://admin:admin@localhost:3000/api/dashboards/db --data @/etc/grafana/dashboards/kafka_exporter_overview.json
我与您分享我在创建 docker 容器期间用于配置仪表板和数据源的脚本:
GRAFANA_URL=$GRAFANA_URL:-http://$GF_SECURITY_ADMIN_USER:$GF_SECURITY_ADMIN_PASSWORD@localhost:3000
#GRAFANA_URL=http://grafana-plain.k8s.playground1.aws.ad.zopa.com
DATASOURCES_PATH=$DATASOURCES_PATH:-/etc/grafana/datasources
DASHBOARDS_PATH=$DASHBOARDS_PATH:-/etc/grafana/dashboards
# Generic function to call the Vault API
grafana_api()
local verb=$1
local url=$2
local params=$3
local bodyfile=$4
local response
local cmd
cmd="curl --verbose -L -s --fail -H \"Accept: application/json\" -H \"Content-Type: application/json\" -X $verb -k $GRAFANA_URL$url"
[[ -n "$params" ]] && cmd="$cmd -d \"$params\""
[[ -n "$bodyfile" ]] && cmd="$cmd --data @$bodyfile"
echo "Running $cmd"
eval $cmd || return 1
return 0
wait_for_api()
while ! grafana_api GET /api/user/preferences
do
sleep 5
done
install_datasources()
local datasource
for datasource in $DATASOURCES_PATH/*.json
do
if [[ -f "$datasource" ]]; then
echo "Installing datasource $datasource"
if grafana_api POST /api/datasources "" "$datasource"; then
echo "installed ok"
else
echo "install failed"
fi
fi
done
install_dashboards()
local dashboard
for dashboard in $DASHBOARDS_PATH/*.json
do
if [[ -f "$dashboard" ]]; then
echo "Installing dashboard $dashboard"
if grafana_api POST /api/dashboards/db "" "$dashboard"; then
echo "installed ok"
else
echo "install failed"
fi
fi
done
configure_grafana()
wait_for_api

exit 0
希望这个答案可以帮助别人。
