when you look into your clearpass app in splunk, you can see the missing fields that are aliased here... i.e $SPLUNK_HOME/etc/apps/ClearPassOnSplunk_2/default/props.conf..
FIELDALIAS-cppm-24 = framed_ip_address AS ip_address
FIELDALIAS-cppm-016 = username as user_name
FIELDALIAS-cppm-acctnasip = nas_ip_address AS nas_ip
FIELDALIAS-cppm-019 = nad_ip AS nas_ip
FIELDALIAS-cppm-910 = host_mac AS mac_address
FIELDALIAS-cppm-911 = end_host_id AS mac_address
FIELDALIAS-cppm-911 = mac_address AS end_host_id
#FIELDALIAS-cppm-host = ClearPass_Server AS host
Let's take FIELDALIAS-cppm-24 = framed_ip_address AS ip_address, in this case you need to have either ip_address or framed_ip_address in your raw data, due to a change in FIELDALIAS behavior in 7.2...you have to change your configs like this...
#FIELDALIAS-cppm-24 = framed_ip_address AS ip_address
EVAL-ip_address = coalesce(ip_address, framed_ip_address)
so, before making any changes, I would check the raw logs on the source host(may be a syslog) to make sure I have the required fields in the log file itself or Splunk is not parsing the fields correctly...??
