Subject: [InfluxData Community] [Collect] Inputs.exec not creating data

Hi all, I recently built a pfSense router, and installed the Telegraf package to write metrics to my InfluxDB.  However, the base Telegraf package for pfSense does not have a measurement for CPU Temperature.  So, I figured I could add an inputs.exec entry to the "additional configuration for Telegraf" box.

Here's what I entered:
  commands = ["sysctl -n dev.cpu.0.temperature | tr -d 0.C"]
  name_override = "cpu_temp"
  timeout = "5s"
  data_format = "influx"
    cpu = "cpu0"</pre>

However, this does not result in a new measurement.  As far as I can tell, it's doing nothing. I know that user account access can be an issue, but as far as I can tell there is only one user on my pfSense, and that user has full administrator access.
Can anyone point me in the right direction?
