Error logging Firewall

[j-fragoso]

Hello everybody,

When I access to firewall I can see the next:

HMS5510-CPD-RC5-FW3# sh logging setting

Syslog logging: enabled

    Facility: 20

    Timestamp logging: enabled

    Standby logging: disabled

    Debug-trace logging: disabled

    Console logging: level debugging, 13836552 messages logged

    Monitor logging: level informational, 73022456 messages logged

    Buffer logging: level informational, 73022456 messages logged

    Trap logging: level informational, facility 20, 73022456 messages logged

        Logging to Inside CiscoWorks errors: 19  dropped: 18144

    History logging: level informational, 73022456 messages logged

    Device ID: disabled

    Mail logging: disabled

    ASDM logging: level informational, 73022456 messages logged

What is the meaning of this line?:

Logging to Inside CiscoWorks errors: 19  dropped: 18144

Thanks in advance

The errors count refers to the number of times the firewall sent a syslog, and received an ICMP port unreachable back from the syslog server (i.e. the number of times the syslog server was done when the firewall sent a syslog message).  The dropped counter indicates how many messages were dropped in a five second window when the host was unreachable.
