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 elements that the Ping Probe generates. Not all the elements described are generated for each event; the elements that the probe generates depends upon the event type.

Table 1. Elements
Element name	Element description
`$alias`	This element identifies the alias of the host.
`$host`	This element shows the name of the host.
`$icmp_stats`	This element contains the standard ICMP statistics of the host.
`$ip_address`	This element shows the IP address of the host machine.
`$poll_rate`	This element displays time after which the probe pings the host.
`$status`	This element indicates the status of the host. Possible values are: `unreachable`: the host has failed to respond `responded`: the host has responded `alive`: the host has responded after previously failing to respond `slow`: the host has taken longer than trip time but less than poll-rate to respond `noaddress`: the probe cannot find the IP address of the host `removed`: the host is removed from the ping file `newhost`: the host is added to the ping file
`$timeout_time`	This element displays the time (in milliseconds) within which the probe expects the host to respond before assuming that it will not respond to that ping attempt.
`$trip_time`	This element displays time (in milliseconds) within which the probe expects the host to respond to a ping before deeming the host to be slow.
