Chapter 1 What’s New for FortiOS 5.2.1 : Logging and Reporting : Accessing Policy-specific Logs from the Policy List
  
Accessing Policy-specific Logs from the Policy List
In FortiOS 5.2, the log viewer can be opened directly from the policy table, with filters applied automatically to show only the logs relating to that policy. To view these logs, right-click on the Seq.# column for the policy and select Show Matching Logs.
The log viewer will filter using the Policy UUID if it is enabled. If not, the Policy ID will be used.
