Hi.
I've got a fully patched Solaris 10 U7 Sparc system, on which
I enabled SNMP disk monitoring by adding those lines to the
/etc/sma/snmp/snmpd.conf configuration file:
disk / 5%
disk /tmp 10%
disk /data 5%
That's supposed to mean, that I see <5% available on / to be
critical, <10% on /tmp and <%5 on /data. And it's also supposed
to mean, that I want to see available space on those directories,
ie. filesystems.
I then did a snmpwalk -t 30 -v2c -cpublic winds07 .1.3.6.1.4.1.2021.9,
to get all the values; I got:
UCD-SNMP-MIB::dskIndex.1 = INTEGER: 1
UCD-SNMP-MIB::dskIndex.2 = INTEGER: 2
UCD-SNMP-MIB::dskIndex.3 = INTEGER: 3
UCD-SNMP-MIB::dskPath.1 = STRING: /
UCD-SNMP-MIB::dskPath.2 = STRING: /tmp
UCD-SNMP-MIB::dskPath.3 = STRING: /data
UCD-SNMP-MIB::dskDevice.1 = STRING: rpool/ROOT/s10s_u7wos_08
UCD-SNMP-MIB::dskDevice.2 = STRING: swap
UCD-SNMP-MIB::dskDevice.3 = STRING: rpool/ROOT/s10s_u7wos_08/data
UCD-SNMP-MIB::dskMinimum.1 = INTEGER: -1
UCD-SNMP-MIB::dskMinimum.2 = INTEGER: -1
UCD-SNMP-MIB::dskMinimum.3 = INTEGER: -1
UCD-SNMP-MIB::dskMinPercent.1 = INTEGER: 5
UCD-SNMP-MIB::dskMinPercent.2 = INTEGER: 10
UCD-SNMP-MIB::dskMinPercent.3 = INTEGER: 5
UCD-SNMP-MIB::dskTotal.1 = INTEGER: 0
UCD-SNMP-MIB::dskTotal.2 = INTEGER: 27593472
UCD-SNMP-MIB::dskTotal.3 = INTEGER: 0
UCD-SNMP-MIB::dskAvail.1 = INTEGER: 0
UCD-SNMP-MIB::dskAvail.2 = INTEGER: 27188624
UCD-SNMP-MIB::dskAvail.3 = INTEGER: 0
UCD-SNMP-MIB::dskUsed.1 = INTEGER: 0
UCD-SNMP-MIB::dskUsed.2 = INTEGER: 404848
UCD-SNMP-MIB::dskUsed.3 = INTEGER: 0
UCD-SNMP-MIB::dskPercent.1 = INTEGER: 2
UCD-SNMP-MIB::dskPercent.2 = INTEGER: 1
UCD-SNMP-MIB::dskPercent.3 = INTEGER: 0
UCD-SNMP-MIB::dskPercentNode.1 = INTEGER: 0
UCD-SNMP-MIB::dskPercentNode.2 = INTEGER: 0
UCD-SNMP-MIB::dskPercentNode.3 = INTEGER: 0
UCD-SNMP-MIB::dskErrorFlag.1 = INTEGER: noError(0)
UCD-SNMP-MIB::dskErrorFlag.2 = INTEGER: noError(0)
UCD-SNMP-MIB::dskErrorFlag.3 = INTEGER: noError(0)
UCD-SNMP-MIB::dskErrorMsg.1 = STRING:
UCD-SNMP-MIB::dskErrorMsg.2 = STRING:
UCD-SNMP-MIB::dskErrorMsg.3 = STRING:
Pay attention to the .1 and .3 values. As you can see SNMP
returns eg. UCD-SNMP-MIB::dskAvail.1 = INTEGER: 0
This is not correct:
--($ ~)-- LC_ALL=C /bin/df -h /
Filesystem size used avail capacity Mounted on
rpool/ROOT/s10s_u7wos_08
274G 4.0G 261G 2% /
I would've expected that SNMP would've returned 261G for
dskAvail. But most certainly not 0 (unless there's 0 space
available, of course...)!
Are the dskTotal, dskAvail and dskUsed figures not supported
on ZFS?
I'm using the SMA snmp daemon that comes with Solaris 10.
Thanks,
Alexander
