Why each option
The `show firewall log` command displays detailed log entries for packets that have triggered a `log` action within a firewall filter. This command provides specific information about network traffic evaluated by the firewall.
The `show firewall counter` command displays statistical counts for packets that match specific firewall filter terms, not detailed log entries.
The `show firewall log` command is specifically designed to display the contents of the firewall filter log buffer, which stores information about packets that match a firewall filter term with the `log` action.
The `show log messages` command displays general system log messages, which might include firewall events if configured to syslog, but it's not the primary command for firewall filter-specific logs.
The `show services accounting usage` command displays usage statistics for network services like NAT or subscribers, not firewall event logs.
