A simple command-line tool to validate InfluxDB line protocol from stdin.

• Real-time validation of InfluxDB line protocol
• Color-coded output (green for valid, red for errors)
• Uses Telegraf's Influx parser for accurate validation and sanity checking of ILP going to telegraf

Build it:

go mod tidy
go build ./cmd/ilplint

Use it:

# Pipe input into the tool
echo "measurement,tag1=value1 field1=123 1625145600000000000" | ./ilplint

# Validate from file
cat measurements.lp | ./ilplint

I was ripping my hair out with errors from telegraf about ILP produced by my exec inputs. It turned out to be that I didn't explicitly specify data_format = "influx" but still, this can be useful for spotting errors in ILP output.
