type confusion in zfs input module #4059
Description
Bug report
Relevant telegraf.conf:
# Read metrics of ZFS from arcstats, zfetchstats, vdev_cache_stats, and pools
[[inputs.zfs]]
## ZFS kstat path. Ignored on FreeBSD
## If not specified, then default is:
# kstatPath = "/proc/spl/kstat/zfs"
## By default, telegraf gather all zfs stats
## If not specified, then default is:
# kstatMetrics = ["arcstats", "zfetchstats", "vdev_cache_stats"]
## By default, don't gather zpool stats
#poolMetrics = true
System info:
∴uname -rms
FreeBSD 12.0-CURRENT amd64
∴telegraf version
Telegraf v1.5.3 (git: unknown unknown)
Steps to reproduce:
- Enable
[[inputs.zfs]]with default arguments - observe
/var/log/telegraf.log
