{ "log": { "level": "error", "message": "oh no!" }, "date": "0", "stream": "stream1" }
{ "log": { "level": "info", "message": "hello world" }, "date": "0", "stream": "stream2" }
' | curl -X POST -H 'Content-Type: application/stream+json' --data-binary @- \
  'http://localhost:9428/insert/jsonline?_stream_fields=stream&_time_field=date&_msg_field=log.message'

查询日志

# 查询所有
curl http://localhost:9428/select/logsql/query -d 'query=log.level:*'

# 查询 error 日志
curl http://localhost:9428/select/logsql/query -d 'query=log.level:error'

浏览器打开：http://127.0.0.1:9428/select/vmui/?#/

输入：log.level:*`` 可看见刚刚导入的日志。

注意: 目前 VictoriaLogs 还不支持通过 grafana 来查询
