Hi there,

I am currently getting these errors:  
2021-03-06T12:29:01Z E! [inputs.exec] Error in plugin: exec: exit status 1 for command ‘iperf3 -c 201.1.1.4 -u --get-server-output --json’:  
2021-03-06T12:29:01Z E! [inputs.exec] Error in plugin: exec: exit status 1 for command ‘iperf3 -c 201.1.1.4 -i 0.5 --json’:  
2021-03-06T12:29:01Z E! [inputs.exec] Error in plugin: exec: exit status 1 for command ‘iperf3 -c 201.1.1.4 -i 0.5 --json’:  
2021-03-06T12:29:01Z E! [inputs.exec] Error in plugin: exec: exit status 1 for command ‘iperf3 -c 201.1.1.4 -i 0.5 --json’:

are these errors normal? as the server is displaying results and have connection to the client.

Please help. Thank you in advanced!

Best  
Debi

No, the call to `iperf3` returns an error.  
I suspect your `iperf3` call is either incorrect or the ip address is unreachable.

The _inputs.exec_ plugin may have problems with multiline JSON output. Just pipe the _iperf3_ output into `jq -c` to transform it to a one line JSON output.

BTW: I want to measure upload and download bandwidth one after the other so I created a shell script:

```auto
#!/bin/bash
#
# Run iperf3 and extract end.sum_received.bits_per_second by using jq.
# --omit 5: ignore the first 5 measurements to let the connection warm up.
#
# See
# - https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
# - https://github.com/influxdata/telegraf/blob/master/plugins/inputs/exec/README.md
#

SERVER=your-iperf3-server.tld

download=$(/usr/bin/iperf3 --client ${SERVER} --json --reverse --omit 5 \
	| /usr/bin/jq .end.sum_received.bits_per_second)

upload=$(/usr/bin/iperf3 --client ${SERVER} --json --omit 5 \
	| /usr/bin/jq .end.sum_received.bits_per_second)

echo "{\"download\":$download,\"upload\":$upload}"

```

Which is used in Telegraf like this:

```auto
[[inputs.exec]]
  commands=["/path/to/script"]
  interval = "30m"
  timeout = "10m"
  data_format = "json"
  name_override = "iperf"

```
