#omit_segments_with(regex) ⇒ Object
return a new transaction sample that treats segments with the given regular expression in their name as if they were never called at all.

#prepare_to_send(options = {}) ⇒ Object
Return a new transaction sample that can be sent to the New Relic service. This involves potentially one or more of the following options
:explain_sql : run EXPLAIN on all queries whose response times equal the value for this key
(for example :explain_sql => 2.0 would explain everything over 2 seconds. 0.0 would explain everything.)
:keep_backtraces : keep backtraces, significantly increasing size of trace (off by default)
:record_sql => [ :raw | :obfuscated] : copy over the sql, obfuscating if necessary
