Upstream tracker https://sourceforge.net/tracker/?func=detail&atid=112694&aid=1445722&group_id=12694 Use the (standard) HOST-RESOURCES-MIB::hrStorageTable instead of the (proprietary ) UCD-SNMP-MIB::dskTable. |
Description of problem: snmpget return negative value of -2^31 (-2147483648) for partition larger than 2^31 Kbytes (>2Tb) Version-Release number of selected component (if applicable): Up to 5.2.1.2-fc4.1 How reproducible: Steps to Reproduce: 1. Create mountpoint with size >2Tb 2. Setup snmp 3. Run snmpwalk/snmpget for given partition (doesn't matter local or remote) Actual results: -2147483648 You will see wrong values like this: $ snmpget [params...] .1.3.6.1.4.1.2021.9.1.6.6 UCD-SNMP-MIB::dskTotal.6 = INTEGER: -2147483648 Expected results: 3Tb free actually: $ df ... /dev/mapper/raid1/vol1 4285534816 760017152 3525517664 18% /raid So result should be like this: UCD-SNMP-MIB::dskTotal.6 = INTEGER(maybe UNSIGNED or INTEGER32): 3525517664 Additional info: dskTotal described in /usr/share/snmp/mibs/UCD-SNMP-MIB.txt as Integer32, so wrong results are expected for >2Tb partition. No luck for replacing type by Unsigned32 (possible workaround for <4Tb partitions which never be negative size): $ grep -A1 dskTotal /usr/share/snmp/mibs/UCD-SNMP-MIB.txt dskTotal Unsigned32, dskAvail Integer32, -- dskTotal OBJECT-TYPE SYNTAX Unsigned32 $ UCD-SNMP-MIB::dskTotal.6 = Wrong Type (should be Gauge32 or Unsigned32): INTEGER: -2147483648
