原始文件

$ < galera-healthcheck.stdout.log  jq '.' | head -n 40
{
  "timestamp": "1499779398.544612646",
  "source": "Galera Healthcheck",
  "message": "Galera Healthcheck.Opened DB connection",
  "log_level": 1,
  "data": {
    "dbHost": "0.0.0.0",
    "dbPort": 3306,
    "dbUser": "galera-healthcheck"
  }
}
{
  "timestamp": "1499779398.544713974",
  "source": "Galera Healthcheck",
  "message": "Galera Healthcheck.Serving healthcheck endpoint",
  "log_level": 1,
  "data": {
    "url": "http://0.0.0.0:9200/"
  }
}
{
  "timestamp": "1499779398.544794559",
  "source": "Galera Healthcheck",
  "message": "Galera Healthcheck.Attempting to GET endpoint...",
  "log_level": 1,
  "data": {
    "url": "http://0.0.0.0:9200/"
  }
}
{
  "timestamp": "1499779398.545407295",
  "source": "Galera Healthcheck",
  "message": "Galera Healthcheck.Failed to process request",
  "log_level": 2,
  "data": {
    "error": "Cannot get status from galera"
  }
}
{
  "timestamp": "1499779398.545511246",

我希望使用相同的原始文件,但是人类可读形式的时间戳。

我试过了:

< galera-healthcheck.stdout.log  jq 'map(if .timestamp then .timestamp |= todate else . end)'

并且文件

中的每一行都出现此错误

第一次回答后更新:

  

将电话放到'地图'。

     

'todate'期望其输入为数字,所以   你需要添加一个'tonumber'的电话。

时间戳仍然是时代格式,不是人类可读的:

< galera-healthcheck.stdout.log  jq '(if .timestamp then .timestamp |= tonumber else . end)' | head
{
  "timestamp": 1499779398.5446126,
  "source": "Galera Healthcheck",
  "message": "Galera Healthcheck.Opened DB connection",
  "log_level": 1,
  "data": {
    "dbHost": "0.0.0.0",
    "dbPort": 3306,
    "dbUser": "galera-healthcheck"
  }

答案 0 :(得分:1)

  1. 将通话发送至&#39; map&#39;。

  2. &#39; TODATE&#39;期望其输入为数字,因此您需要添加对“#ton;”的调用:

    .timestamp |= (tonumber|todate)
