How to view webfiltering logs in in a syslog file
Cause:

Solution:

To configure a syslog file and view web filtering logs

The following procedure outlines the creation of a syslog file to capture web filtering logs. The match statement of "WEBFILTER_" is used to capture all web filtering logs.

[edit]

root@SRX # set system syslog file webfilter-log match WEBFILTER_ any any

The following output displays the log file. The default action was set to 'permit-and-log'. This is why permitted URLs are shown in the log file.

To view only the blocked URLs, run the same command but match on URL_BLOCKED. This displays only the web filtering URL blocked log events. The log file configuration could also be modified to match 'WEBFILTER_URL_BLOCKED'. This would write only these types of events to the log file.
