How to Convert field into tag by a given measurement

InfluxDB 2
1

Hi All,
I wrote one script for reading the oracle log file and the script successfully read the oracle log as per my requirement.
But the issue is at a time (with same time)there are 5 log is generated but in influxDB only first log is coming and another four log is not coming because 5 log is coming in a same time.
So I need to change the tag into fields as per the line protocol of inlfuxdb.
Is there any way to change the filed into tag
