Feature: SNMP Alerts

Background: Use Simple Network Management Protocol (SNMP) to configure the SNMP agent on CloudStack Management Server to generate asynchronous events, which are called traps. The traps are generated whenever there are abnormal conditions as observed by the Management Server. The traps are then sent to a remote device called a trap listener, which signals the abnormal condition on CloudStack.  The trap listener is typically an external management station such as Microsoft SCOM, HP Openview etc.

Requirements:

-          Generate SNMP traps that can be consumed by external monitoring systems such as SCOM/OpenView etc.

-          Generate traps compliant with SNMP v1, v2 (top priority is for v2)

-          Provide the required MIBs

-          Ability to specify trap listeners to which we send the generated trap messages

-          provides a set of condition entities (SNMP alarms) and severity level

-          Up to 20 trap listeners for receiving traps

-          configure to send trap messages to a trap listener on the basis of a severity level

-          Support registration of trap listeners and alarm types using new CloudStack APIs

Open Questions: Do events get generated from MS only or from MS and system VMs? If system VMs, is there connectivity? How do you specify what type of events to generate alerts for? How do you classify the event types? Do we need more than 20 trap listeners? do we need to support V3?
