.... and nothing else

System info

Debian 12 x64 with Telegraf v1.33.0 deb pkg

Docker

No response

Steps to reproduce

Use the given config on a Linux x64 equipped machine

Expected behavior

"poolMetrics = true" and "datasetMetrics = false" i would expect output simiar to that when the "zpool iostat -vl" command is run.

"poolMetrics = false" and "datasetMetrics = true" i would expect datasetMetrics output.

Actual behavior

"poolMetrics = true" and "datasetMetrics = false" gives datasetMetrics instead.

"poolMetrics = false" and "datasetMetrics = true" gives nothing.
