grafana仪表盘的导出是前端应用处理，我们想要导出grafana中的所有的仪表盘的时候可以通过调用grafna的API接口来完成导入导出的操作。这里提供一个导入导出功能集合的脚本用于完成这项任务：
脚本执行的环境要求：
1、有curl工具；
2、有jq工具，一般centos默认不会安装需要自行百度安装(当然也可以不用jq工具，直接用shell脚本来处理json内容，但是比较麻烦)；
dashboard_export_import.sh脚本使用：
使用的时候替换脚本中开头的相关变量：
SOURCE_GRAFANA_ENDPOINT="源grafana的地址，如：http://127.0.0.1:3000"
DEST_GRAFANA_ENDPOINT="目标grafana的地址，如：http://127.0.0.1:3100"
SOURCE_GRAFANA_API_KEY='访问源grafana的api密钥'
DEST_GRAFANA_API_KEY='访问目标grafana的api密钥'
若grafana都是通过匿名访问无效密钥，那么无需填写，脚本中删除引用密钥的变量即可
导出仪表盘到 "DASH_DIR" 变量指定的目录下，执行如下方式导出：
$ sh dashboard_export_import.sh -e
导入仪表盘到目标grafana中，执行如下方式导入：
$ sh dashboard_export_import.sh -i
脚本内容如下：
#!/bin/sh
# env var info
SCRIPT_PATH=$(cd $(dirname $0) && pwd -P)
DASH_DIR=${SCRIPT_PATH}/backup_dashboard
DASH_DB_FILE=${DASH_DIR}/das_db.json
SOURCE_GRAFANA_ENDPOINT="source_grafana_endpoint_here"
DEST_GRAFANA_ENDPOINT='dest_grafana_endpoint_here'
SOURCE_GRAFANA_API_KEY='source_grafana_api_key_here'
DEST_GRAFANA_API_KEY='dest_grafana_api_key_here'
