The System Log
The System Log (syslog) page provides you with system log information for the appliance.
You can audit activity on your system in two ways. The appliances that are part of the Firepower System generate an audit record for each user interaction with the web interface, and also record system status messages in the system log.
The system log displays each message generated by the system. The following items are listed in order:
-
the date that the message was generated
-
the time that the message was generated
-
the host that generated the message
-
the message itself
Viewing the System Log
System log information is local. For example, you cannot use the Firepower Management Center to view system status messages in the system logs on your managed devices.
You can filter messages using most syntax accepted by the UNIX file search utility Grep. This includes using Grep-compatible regular expressions for pattern matching.
Before you begin
You must be an Admin or Maintenace user and be in the Global domain to view system statistics.
