iscsiInstSessionFailure

Module: ISCSI-MIB

OID (symbolic): ISCSI-MIB::iscsiInstSessionFailure

OID (numeric): 1.3.6.1.2.1.142.0.3

Node type: NOTIFICATION-TYPE

Description: Sent when an active session is failed by either the initiator or the target.

To avoid sending an excessive number of notifications due to multiple errors counted, an SNMP agent implementing this notification SHOULD NOT send more than 3 notifications of this type in any 10-second time period.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' ISCSI-MIB::iscsiInstSessionFailure
snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.142.0.3

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:50981->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (330241317) 38 days, 5:20:13.17

Start monitoring Vendor-neutral IETF standard (iSCSI targets, initiators, storage servers/SANs) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the ISCSI-MIB::iscsiInstSessionFailure OID value, configure state conditions and alerts, and monitor any Vendor-neutral IETF standard (iSCSI targets, initiators, storage servers/SANs) from a single console.
