IBM Tivoli Universal Agent situations

Overview

IBM Tivoli Universal Agent offers a set of predefined situations for the SNMP Data Provider that address some of the most common exception conditions. You can use these situations to begin monitoring almost immediately, or as templates for creating your own situations. All of the predefined situations are enabled when shipped.

Descriptions

IBM Tivoli Universal Agent includes the following predefined situations.

MB2_interfaceDown triggers an exception condition when a network interface is down.

MIB-2IFTABLE00.ifOperStatus EQ 2

MB2_interfaceInError triggers an exception condition when either the number of inbound packets that contained errors that prevented them from being deliverable to a higher-layer protocol was 20 or more, or the number of inbound packets that were chosen to be discarded, even though no errors had been detected, was 100 or more.

MIB-2IFTABLE00.ifInErrors *GE 20
OR
MIB-2IFTABLE00.ifInDiscards *GE 100

MB2_interfaceOutError triggers an exception condition when either the number of outbound packets that were not transmitted because of errors is 20 or more or the number of outbound packets that were chosen to be discarded is 100 or more.

MIB-2IFTABLE00.ifOutErrors *GE 20
OR
MIB-2IFTABLE00.ifOutDiscards *GE 100

MB2_ipInError monitors three types of inbound IP datagrams errors. An exception is triggered for any of the following conditions:

MIB-2IP00.ipInHdrErrors GE 5
OR
MIB-2IP00.ipInUnknownProtos GE 20
OR
MIB-2IP00.ipInDiscards *GE 20

MB2_ipOutError triggers an exception condition when either the number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but that were discarded is 20 or more, or the number of IP datagrams discarded because no route could be found to transmit them to their destination is 20 or more.

MIB-2IP00.ipOutDiscards GE 20
OR
MIB-2IP00.ipOutNoRoutes GE 20

MB2_ipFragmentationError triggers an exception condition when the number of IP datagrams that have been discarded because they needed to be fragmented at this entity, but might not be, is 10 or more.

MIB-2IP00.ipFragFails GE 10

MB2_icmpError triggers an exception condition when either the number of ICMP messages that the entity received but determined to have ICMP-specific errors is 20 or more, or the number of ICMP messages that this entity did not send because of problems discovered within ICMP (such as a lack of buffers) is 20 or more.

MIB-2ICMP00.icmpInErrors GE 20
OR
MIB-2ICMP00.icmpOutErrors GE 20

MB2_tcpError triggers an exception condition when the total number of segments received in error is 10 or more.

MIB-2TCPCONNTABLE00.tcpInErrs GE 10

MB2_udpError triggers an exception condition when the number of received UDP datagrams that might not be delivered for reasons other than the lack of an application at the destination port is 10 or more.

MIB-2UDP00.udpInErrors GE 10

MB2_egpError triggers an exception condition when either the number of EGP messages received that proved to be in error is 10 or more, or the number of locally generated EGP messages not sent because of resource limitations within an EGP entity is 10 or more.

MIB-2EGP00.egpInErrors GE 10
OR
MIB-2EGP00.egpOutErrors GE 10

MB2_egpNeighError triggers an exception condition when either the number of EGP messages received from this EGP peer that proved to be in error is 10 or more, or the number of locally generated EGP messages not sent to this EGP peer because of resource limitations within an EGP entity is 10 or more.

MIB-2EGP00.egpNeighInErrs GE 10
OR
MIB-2EGP00.egpNeighOutErrs GE 10

MB2_snmpOperationViolations triggers an exception condition when either the total number of SNMP messages delivered to the SNMP protocol entity that used an SNMP community name not known to said entity has exceeded 10, or the total number of SNMP Messages delivered to the SNMP protocol entity that represented an SNMP operation that was not allowed by the SNMP community named in the message has exceeded 10.

MIB-2SNMP00.snmpInBadCommunityNames GE 10
OR
MIB-2SNMP00.snmpInBadCommunityUses GE 10

NETWORK_not_responding triggers an exception condition when a network is not responding within a reasonable amount of time.

VALUE SNMP-MANAGERNETSUMMARY00.Max_Resptime_ms GT 500

ROUTER_status_offline triggers an exception condition when a router is offline.

SCAN SNMP-MANAGERROUTER00.Router_Status EQ Offline

TRAP_category_errors triggers an exception condition when an SNMP trap was received with the error category.

SCAN SNMP-MANAGERTRAP00.Category EQ "Error Events"

TRAP_severity_errors triggers an exception condition when an SNMP trap was received with the severity "error:".

SCAN SNMP-MANAGERTRAP00.Severity EQ Critical
OR
SCAN SNMP-MANAGERTRAP00.Category EQ "Major Error"

HOTLIST_offline triggers an exception condition when a managed node list item shows the status "offline".

SCAN SNMP-MANAGERMANAGED-NODES00.Node_Status EQ Offline
