From the zpool_influxdb.8 manual page:
zpool_influxdb produces InfluxDB-line-protocol-compatible metrics from
zpools. Like the zpool command, zpool_influxdb reads the current pool
status and statistics. Unlike the zpool command which is intended for
humans, zpool_influxdb formats the output in the InfluxDB line protocol.
The expected use is as a plugin to a metrics collector or aggregator,
such as Telegraf.
zpool_influxdb is installed into /usr/libexec/zfs/
