[inputs.exec]: metric parse error: expected field at offset 110:

[timcooijmans]

Hi,

My previously working input.exec script suddenly doesn't work anymore since the update to Telegraf 1.6.0.

I'm getting the following error:
Error in plugin [inputs.exec]: metric parse error: expected field at offset 110: "energy,meter=main imported_1=23786.317,exported_1=469.162,imported_2=23870.795,exported_2=1060.053,l1_import=00.254,l1_export=00.000,l2_import=00.201,l2_export=00.000,l3_import=00.693,l3_export=00.000\n"

Config:

[[inputs.exec]]
        commands = ["python /etc/telegraf/readmeter.py"]
        timeout = "20s"
        data_format = "influx"

Any idea what's going wrong?

It could be caused by this commit: 8e51568
You should check if your python command return a correct exit code...

We rewrote the line protocol parser in 1.6, I expect this is just a bug in the new parser. Looks like it is caused by the double leading zero on floats: 00.693, if you can change these to 0.693 it should pass in 1.60, but I'll fix it proper for 1.6.1.
