Hi,
Only just started looking into this, but it seems that all Ubuntu 18.04 hosts which auto-update have pulled snmpd up to 5.7.3+dfsg-1.8ubuntu3.2 (from ubuntu3.1) are now no longer providing 'any' of their storage info under hrStorageEntry
# /usr/bin/snmpbulkwalk -t '5' -r '3' -v2c -c *** -Pud -OQUs -m HOST-RESOURCES-MIB:HOST-RESOURCES-TYPES -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'target-device':'161' hrStorageEntry
hrStorageEntry = No Such Object available on this agent at this OID
But - after a restart of SNMPD service on the target-device, the expected response returns correctly:
hrStorageIndex.1 = 1 hrStorageIndex.3 = 3 hrStorageIndex.6 = 6 hrStorageIndex.7 = 7 hrStorageIndex.8 = 8 hrStorageIndex.10 = 10 hrStorageType.1 = hrStorageRam hrStorageType.3 = hrStorageVirtualMemory hrStorageType.6 = hrStorageOther hrStorageType.7 = hrStorageOther hrStorageType.8 = hrStorageOther <...>
HOWEVER - a re-discovery and poll of the device by Observium kills it immediately, and it goes back to:
hrStorageEntry = No Such Object available on this agent at this OID
It has impacted every 18.04 device we have which auto-updates.
Anyone else seen this?
