problem with invalid rpn expression

[iluv8250]

hi all!
i'm newbie. now i try to monitor about hard disk usage. I found a introduction from http://docs.cacti.net/usertemplate:data ... disk_usage . but after I import and create graph for device, it has problem:

/usr/bin/rrdtool graph - \

GPRINT:cdefa:LAST:" Current\:%8.2lf %s" \

RRDTool Says:

ERROR: invalid rpn expression in: a,query_hrStorageAllocationUnits,*

I think cacti can't query hrStorageAllocationUnits. But I don't know how to fix this problem. I'm using cactiez os and cacti version 0.8.8a. thank so much!!!!!

Hi

i have this issue too,
after replacing data query of hrStorageTable.xml on <cacti-path>/resource/snmp_query with other one, this issue happened. when i run verbose query for hrstoragetable data query it return below result

+ Running data query [40].
+ Found type = '3' [SNMP Query].
+ Found data query XML file at '/usr/share/cacti/resource/snmp_queries/hrStorageTable.xml'

this result show that after executing hrStorageAllocationUnits, there is no result has been found.
when i run snmpwalk with OID .1.3.6.1.2.1.25.2.3.1.4 , it work correctly:

snmpwalk -v2c -c [community string] xxx.xxx.xxx.xxx .1.3.6.1.2.1.25.2.3.1.4
HOST-RESOURCES-MIB::hrStorageAllocationUnits.1 = INTEGER: 0 Bytes
HOST-RESOURCES-MIB::hrStorageAllocationUnits.2 = INTEGER: 4096 Bytes
HOST-RESOURCES-MIB::hrStorageAllocationUnits.3 = INTEGER: 4096 Bytes
HOST-RESOURCES-MIB::hrStorageAllocationUnits.4 = INTEGER: 0 Bytes
HOST-RESOURCES-MIB::hrStorageAllocationUnits.5 = INTEGER: 65536 Bytes
HOST-RESOURCES-MIB::hrStorageAllocationUnits.6 = INTEGER: 65536 Bytes
