Static elements

The probe breaks event data down into tokens and parses them into elements. Elements are used to assign values to ObjectServer fields; the field values contain the event details in a form that the ObjectServer understands.

The following table describes the static elements that the probe generates:

Table 1. Static elements
Element name	Element description
`$community`	This element contains the SNMP community string.
`$enterprise`	This element contains the SNMP enterprise string.
`$Eventcount`	This element shows the number of event.
`$generic-trap`	This element contains the SNMP generic trap integer value. Applies only to traps in V1 format.
`$IPAddress`	This element contains the IP address of the device.
`$ipStatus`	This element indicates the management status of the device that originated the trap. Note: The probe only generates the ipStatus element if the GetIpStatus property is set to 1.
`$LastToken`	This element corresponds to the last varbind in the trap.
`$Node`	This element indicates the node from which the trap originated. Note: If the NoNameResolution property is set to 0, the probe resolves the host name and sets the `$Node` element to this value. If the host name is not resolvable by the Domain Name Server, the probe sets the `$Node` element to the IP address.
`$notify`	This element contains the SNMP notify value. Applies only to traps in V2 format.
`$Sequence`	This element indicates the number of times the probe has been run.
`$SNMP_Version`	This element indicates which version of the SNMP software is monitoring the network.
`$Source_Addr`	This element shows the IP address of the source host.
`$specific-trap`	This element contains the SNMP specific trap integer value. Applies only to traps in V1 format.
`$uptime`	This element shows the amount of time (in 100ths of a second) that the agent sending the trap has been running.
`$UUID`	This element contains the unique identifier for an ECS event.
