Splunk Add-on for Imperva SecureSphere WAF: Why does the add-on not correctly parse event names with a space in them when parsing Incapsula log?

I've noticed that the add-on for imperva WAF, when parsing Incapsula logs, doesn't correctly parse event names with a space in them. For example 'Blocked country' or 'Blocked IP' are never parsed and just become NULL. Event names without a space are fine.

Anyone know how to fix this? I know the relevant props. conf entries are

EXTRACT-CEF0 = ^(?P[^\|]+)\|(?P[^\|]+)\|(?P[^\|]+)\|(?P[^\|]+)\|(?P[^\|]+)\|(?[^\|]+)\|(?P\d+)
EXTRACT-CEF_Version,CEF_Vendor,CEF_Product,CEF_DeviceVersion,CEF_SignatureID,CEF_Name,CEF_Severity = ^(?P[^\|]+)\s+\|\s+(?P[^\|]+)\s+\|\s+(?P[^\|]+)\s+\|\s+(?P[^\|]+)\s+\|\s+(?P[^\|]+)\s+\|\s+(?[^\|]+)\s+\|\s+(?P\d+)

However, I don't understand why it wouldn't correctly pick up event names with spaces since [^|]+ means one or more characters not match caret or pipe character.

Anyone have ideas or already resolved this?

Hi gordo

Let me know if you still have problem with Imperva Add-On

We implemented it with our Splunk and it is working perfectly
