SAI missing mountpoint from collectd

[gballanti]

Hello,

I'm using SAI to get filesystem usage, unfortunately the mountpoint is not populated, or better it is partial.

The following query (KPI in ITSI)

| mstats min(df.free) as "df_free" max(df.used) as "df_used" WHERE `sai_metrics_indexes` by host,mount span=30s | eval host_dev = host . ":" . mount

doesn't work because the dimension "mount" is missing. Changing "mount" with "device" I get result without mountpoint.

Trying to change the collectd.conf (red part)

<Plugin df>
FSType "ext2"
FSType "ext3"
FSType "ext4"
FSType "XFS"
FSType "rootfs"
FSType "overlay"
FSType "hfs"
FSType "apfs"
FSType "zfs"
FSType "ufs"
MountPoint "/^/.+/"
ReportByDevice false
ValuesAbsolute false
ValuesPercentage true
IgnoreSelected false
</Plugin>

I get data only from one mountpoint (/boot) the other ones are still missing. I don't understand because the mount dimension is missing and only partial mountpoints are taken.

Is it my fault ?

I use the latest version of SAI, ITSI 4.4.3 and Splunk 8.0.3

Thanks
