Check out fwlogsum. This tool parses the firewall log files (accounting files?) of FW-1 to create reports. This can be used to populate rrdtool databases for trending/reporting. The “art” is maintaining your policy so that changes over time don’t skew the metrics collected.

The MIB’s for FW-1 only provide high level information such as enforcement point status (installed, uninstalled, etc), and packet count on Accept, Deny, Drop, entries.
Personally, I use both SNMP for monitoring/reporting the interface particulars such as utilization, and fwlogsum for a more granular breakdown of the firewall log files.

I've just come across some mention of using SNMP to get log data from FW-1, especially in combination with MRTG. However, I can't seem to find any detailed info on exactly what can be monitored via the MIBs - I've found mention of bits per second by interface, and some mention of being able to pull logged packets. Specifically I'm interested in the ability to pull bandwidth usage by IP address and/or Checkpoint object/group. Is it worth considering SNMP-only monitoring vs. analyzing full log files, especially for the above?? Thanks, Glenn |
