Hi,
Depending on the option you passed to the "fw log" command
(option FWLOGOPTS recommaned value "-ftn") the FW-1 log is
either read from its beginning or from the last entries as
they arrive to the management station.
The server side of FwGold does not use RRD as it stores its
counters in memory and waits for the client to connect and grab
them. It is the client which stores the values onto a RRD
database.
FwGold server is a bit a resource eater because it has to match
each log entry against the user filter configuration which is a
resource intensive task. 100% CPU is nevertheless too much
but then again it really depends on what system you run FwGold
server on, how many log entries per second you have, how complex
your filter definition (userdb.conf) is, etc. etc.
I personally have FwGold server taking 10-15% CPU on a Sun Netra
T1 receiving about 1.5 Million log entries per day.
Regards,
Gianluca
