Palo Alto App (CEF)

Path Finder

Any support for the Common Event Format (CEF)?

We have a requirement to send the logs out in the Common Event Format and the way the app is setup it is not recognizing it. I have changed some of the settings in the transforms.conf file to change the sourcetype on the log entries but the delimiting character is not the same and the fields are all out of sorts.

Has anyone already made these modifications to have the app work? Does the author of the application plan to include different types of formats?

hello Kyle,

there is no plan to support the CEF format in this app. the app conforms to Splunk's common information model and it also conforms to PaloAlto's Syslog specification. you could create field aliases for misc fields in the CEF format. the app's dashboards and views will render appropriately.
