Thomas,

Please share the output of ./discovery.php -h fs-test -m storage -d - it could provide some clues... :-)

Hi

After some digging, i don't think its because of the net-snmp package. It must be something in Observium because the snmpwalk returns the BTRFS filesystem indeed:

snmpwalk -v3 -l authPriv -u *** -a SHA -A *** -x DES -X *** fs-test | grep /var/lib/samba/profiles
-> no output

snmpwalk -v3 -l authPriv -u *** -a SHA -A *** -x DES -X *** fs-test UCD-SNMP-MIB::dskPath
...
-> UCD-SNMP-MIB::dskPath.3 = STRING: /var/lib/samba/profiles
...

snmpwalk -v3 -l authPriv -u *** -a SHA -A *** -x DES -X *** fs-test UCD-SNMP-MIB::dskTable
-> returns output too


Any clues?

Best,
Thomas

Hi

This is because of the following patch beeing missing in the Debian Jessy "snmp" package:

https://sourceforge.net/p/net-snmp/bugs/2502/


https://packages.debian.org/de/source/jessie/net-snmp
ii  snmp                                5.7.2~dfsg-8.1ubuntu3.2                    amd64        SNMP (Simple Network Management Protocol) applications

FYI Ubuntu 14.04 and newer already have it:

Seems like i have to wait until the package gets an update. I don't know to whom to write to though.


Best,
Thomas

It's btrfs, I'm guessing net-snmp does not export this (correctly) via SNMP...

I can't see anything in the default filters which would block this. Are you sure it's present in SNMP?

Hi

Thanks so far! :)

This did the trick for the NFS mounts, but the local filesystem (mounted)

/dev/mapper/vg_data-lv_samba_profiles on /var/lib/samba/profiles type btrfs (rw,relatime,space_cache,subvolid=5,subvol=/)

is still missing.

Do you have any clue (this is the most important filesystem for monitoring)?

Best,
Thomas
