Live updating CSV and influxDB

mdavies23 · August 16, 2023, 11:38am

I have a DDS subscriber that is written in C++ and can output a CSV. These files will have unique names for every run I do. I am trying to get this data into the influxDB live so I can use grafana to view live results. It seems like the telegraf CSV function is for upload fully finished CSVs. Any idea on how to do this? (I can edit the C++ program)

Hello @mdavies23,
Welcome!
What version of InfluxDB are you using?
I recommend using the following telegraf plugin to write CSV to InfluxDB:

github.com

influxdata/telegraf/blob/master/plugins/parsers/csv/README.md

# CSV Parser Plugin

The `csv` parser creates metrics from a document containing comma separated
values.

## Configuration

```toml
[[inputs.file]]
  files = ["example"]

  ## Data format to consume.
  ## Each data format has its own unique set of configuration options, read
  ## more about them here:
  ##   https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
  data_format = "csv"

  ## Indicates how many rows to treat as a header. By default, the parser assumes
  ## there is no header and will parse the first row as data. If set to anything more
  ## than 1, column names will be concatenated with the name listed in the next header row.

Especially if you’re writing data to the CSV often.
