Thanks for the reply. As I mentioned, the message I noted above is only part of a much larger message. The beginning of the message has a timestamp, which Splunk seems to be identifying correctly. But I have BREAK_ONLY_BEFORE_DATE = true, so I don't understand why Splunk would also break at these #012 characters. Clearly the part of the message before those characters is not a timestamp.
I am pretty green, so I opened a support case asking for some assistance and education, but support has been very unhelpful.
What makes this so complex to me is that these messages are also processed by the Cisco ISE TA. My input applies a sourcetype=syslog, but when I view the messages, they have a sourcetype=cisco:ise:syslog. Being inexperienced, I am not quite clear on how this transition happens. But I can tell you that both my syslog sourcetype and cisco:ise:syslog sourcetypes both have BREAK_ONLY_BEFORE_DATE = true.
