Make sure that the UDP service is enabled in the InfluxDB config. This API doesn't tell you if any error occurs. See the official doc for details.
Writers
writeBatch :: (Timestamp time, Foldable f) => WriteParams -> f (Line time) -> IO () Source #
writeByteString :: WriteParams -> ByteString -> IO () Source #
Write a lazy ByteString
Writer parameters
data WriteParams Source #
The full set of parameters for the UDP writer.
Instances
| HasPrecision 'WriteRequest WriteParams Source # | Timestamp precision. In the UDP API, all timestamps are sent in nanosecond but you can specify lower precision. The writer just rounds timestamps to the specified precision. |
