Item "Get iostats" in ZFS pool discovery fix

[cedric-marcoux]

Hello,

the item "Zpool {#POOLNAME}: Get iostats" in ZFS discovery pool value should be changed from
vfs.file.contents[/proc/spl/kstat/zfs/{#POOLNAME}/io]
to
vfs.file.contents[/proc/spl/kstat/zfs/{#POOLNAME}/iostats]

Regards

This fix doesn't work in itself. I had to change the base item key to

vfs.file.regexp[/proc/spl/kstat/zfs/rpool/iostats,"^[0-9]"]

to only return the first line of the file. Then the dependent items work, but always show zero IO operations. Something must have changed in the format of the stats file. Using Zabbix 5.0.27.

Yes, that first line is/became rather useless. zpool iostat is the way.
