Line Protocol
influx write sends Line Protocol to a bucket — pass it inline as a quoted string or from a file with -f, and use --precision to declare the timestamp unit.
The influx write command is the CLI path for ingesting points; it accepts Line Protocol inline or from a file.
--bucket (or -b) picks the destination, and a quoted argument carries one or more lines of Line Protocol.
-f data.lp streams a whole file of points, and --precision tells the server how to interpret your timestamps.
01
-b / --bucket names the destination bucket.
02
A quoted string writes Line Protocol inline.
03
-f reads points from a file for bulk loads.
influx write --bucket metrics --precision s "cpu,host=a usage=0.64 1700000000"
influx write -b metrics -f data.lpRead the implementation
Connect each part of the code to the concept before you type.
2. Timestamp precision
--precision tells InfluxDB how to read the timestamp; s means the number is seconds, not nanoseconds.
--precision s3. Inline Line Protocol
A quoted string passes Line Protocol directly on the command line.
"cpu,host=a usage=0.64 1700000000"4. Write from file
-f reads Line Protocol from a file, one point per line — ideal for bulk loads.
