对不起，我的问题，但我不明白。。。
我想通过telegraf将我的所有机器和应用程序度量作为json写入kafka，然后我想通过telegraf（kafka consumer json data codec）再次读取它们，并将其推送到opentsdb或其他ts。如何从json to be tags中的tags键获取所有值？
kafka中的json示例如下：

{
"fields": {
    "active": 0,
    "activePerOneMillion": 0,
    "cases": 3,
    "casesPerOneMillion": 200,
    "critical": 0,
    "criticalPerOneMillion": 0,
    "deaths": 0,
    "deathsPerOneMillion": 0,
    "oneCasePerPeople": 5010,
    "oneDeathPerPeople": 0,
    "oneTestPerPeople": 16,
    "population": 15029,
    "recovered": 3,
    "recoveredPerOneMillion": 199.61,
    "tests": 928,
    "testsPerOneMillion": 61747,
    "todayCases": 0,
    "todayDeaths": 0,
    "todayRecovered": 0,
    "updated": 1599765513087
},
"name": "http",
"tags": {
    "continent": "North America",
    "country": "Anguilla",
    "countryInfo__id": "660",
    "countryInfo_flag": "https://disease.sh/assets/img/flags/ai.png",
    "countryInfo_iso2": "AI",
    "countryInfo_iso3": "AIA",
    "countryInfo_lat": "18.25",
    "countryInfo_long": "-63.1667",
