#Step 01 –

然後安裝jq:命令列下處理JSON 資料的工具,可以對json資料進行分片、過濾、映射和轉換

# apt install jq

 
#Step 02 –

匯出腳本grafana-dashboard-exporter.sh參考:https://gist.github.com/crisidev/bd52bdcc7f029be2f295

使用方式:

#Step 04 –

這個我還在理解

使用grafana provision
新版Grafana支援使用provision的方式通過yaml配置導入 dashboards | datasources | notifiers 這三種資源到Grafana db中。

/etc/grafana/grafana.ini檔中需要配置provisioning的目錄

[paths]
data = /var/lib/grafana/data
logs = /var/log/grafana
plugins = /var/lib/grafana/plugins
provisioning = /etc/grafana/provisioning
[smtp]
enabled = true
host = smtp.exmail.qq.com:25
...


grafana-dashboard-exporter.sh匯出的代碼可以通過一下python代碼進行轉換得到provision的配置:



 
#Step 05 –

# -*- coding: utf-8 -*-
import os
import json

dirs = [
    "/home/suncle/dockprom/grafana/dashboards/celery",
    "/home/suncle/dockprom/grafana/dashboards/General",
    "/home/suncle/dockprom/grafana/dashboards/k8s",
    "/home/suncle/dockprom/grafana/dashboards/pulsar",
]


def main():
    for d in dirs:
        for f in os.listdir(d):
            filename = "{}/{}".format(d, f)
            if not f.endswith(".json") or f.startswith("."):
                continue
            try:
                with open(filename, "r+") as fp:
                    json_data = fp.read()
                    data = json.loads(json_data)
                    fp.seek(0)
                    fp.write(json.dumps(data["dashboard"], sort_keys=True))  # 字母序
                    print("{}: success".format(filename))
            except Exception as e:
                print("{}: {}".format(filename, e))


if __name__ == "__main__":
    main()
