cef0.claroty.ctd

Introduction

The table cef0.claroty.ctd identifies events in CEF format generated by Claroty CTD.

Tag structure

Events in CEF format don't have a specific tag structure, as explained in Technologies supported in CEF syslog format. They are always sent to a table with the structure cef0.deviceVendor.deviceProduct.

In this case, the valid data tables are:

  • cef0.claroty.ctd 

How is the data sent to Devo?

Learn more about CEF syslog format and how Devo tags these events in Technologies supported in CEF syslog format.

Log samples

The following are sample logs sent to cef0.claroty.ctd. Find how the information will be parsed in your data table under each sample log.

Extra columns

Fields marked as Extra in the table below are not shown by default in data tables and need to be explicitly requested in the query. You can find them marked as Extra when you perform a query so they can be easily identified. Learn more about this in Selecting unrevealed columns.
