Systems and methods for trap monitoring in multi-core and cluster systems
In a multi-core device or clustered system, instead of snmpd polling for configured monitoring values of an entity to determine if reached a threshold, each core in a multi-core system or node in a clustered system triggers information to the snmpd about entities that may be or are generating SNMP traps. A configured threshold T is distributed among the cores or nodes, as the case may be, based on the number of cores or nodes. If there are ‘n’ cores in a multi-core device, and the configured threshold is ‘T’, then each core checks for a per-core threshold value ‘T/n’. If there are ‘n’ nodes in a clustered system, and the configured threshold is ‘T’, then each node checks for a per-node threshold value ‘T/n’. According to the pigeonhole principle, if an entity has reached or exceeded the threshold ‘T’, then the entity must have reached or exceeded a value of ‘T/n’ on at least one core or node. Upon the entity crossing a ‘T/n’ value on any core or node, the core or node informs snmpd about this entity. Snmpd then gathers information about this entity from all the cores and checks for the threshold ‘T’. |

A second external terminal of the first light-emitting element and a first external terminal of the second light-emitting element are each bonded to one of the one or more third pads. A second external terminal of the second light-emitting element is bonded to the second pad. |

Semiconductor light emitting element
A semiconductor light emitting element includes a first conductive type semiconductor layer, a light emitting layer, and a second conductive type semiconductor layer disposed in this order. The semiconductor light emitting element includes first and second electrodes, a first insulating film and a translucent electrode. The first electrode is provided on the first conductive type semiconductor layer and includes a first pad portion and a first extending portion. The first insulating film covers the first extending portion. The translucent electrode is connected to an upper surface of the second conductive type semiconductor layer and extends over the first insulating film. The second electrode is connected to the translucent electrode at a position on the first insulating film. The second electrode includes a second pad portion and a second extending portion extending along the first extending portion so as to be superimposed over the first extending portion. |
