InfluxDB Line Protocol
Insert data
GreptimeDB supports HTTP InfluxDB Line protocol. You can write data via /influxdb/write API:
shell
curl -i -XPOST "http://localhost:4000/v1/influxdb/write?db=public&precision=ms" \
--data-binary \
'monitor,host=127.0.0.1 cpu=0.1,memory=0.4 1667446797450
monitor,host=127.0.0.2 cpu=0.2,memory=0.3 1667446798450
monitor,host=127.0.0.1 cpu=0.5,memory=0.2 1667446798450'curl -i -XPOST "http://localhost:4000/v1/influxdb/write?db=public&precision=ms" \
--data-binary \
'monitor,host=127.0.0.1 cpu=0.1,memory=0.4 1667446797450
monitor,host=127.0.0.2 cpu=0.2,memory=0.3 1667446798450
monitor,host=127.0.0.1 cpu=0.5,memory=0.2 1667446798450'The /influxdb/write supports query params including:
dbspecify which db to write,publicby default.precision, precision of timestamps in the line protocol. Acceptsns(nanoseconds),us(microseconds),ms(milliseconds) ands(seconds), nanoseconds by default.
You can also omit the timestamp when sending requests. GreptimeDB will use the current system time (in UTC) of the host machine as the timestamp. For example:
shell
curl -i -XPOST "http://localhost:4000/v1/influxdb/write?db=public&precision=ms" \
--data-binary \
'monitor,host=127.0.0.1 cpu=0.1,memory=0.4
monitor,host=127.0.0.2 cpu=0.2,memory=0.3
monitor,host=127.0.0.1 cpu=0.5,memory=0.2'curl -i -XPOST "http://localhost:4000/v1/influxdb/write?db=public&precision=ms" \
--data-binary \
'monitor,host=127.0.0.1 cpu=0.1,memory=0.4
monitor,host=127.0.0.2 cpu=0.2,memory=0.3
monitor,host=127.0.0.1 cpu=0.5,memory=0.2'
