Getting Data In

SAI missing mountpoint from collectd



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( 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

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
