*The following table recommends the disk space and RAM
size requirements of the system where Firewall Analyzer is
installed. The disk space and RAM size requirements depends
on the number of devices sending log information to Firewall
Analyzer, the number of firewall log records received per
second or the firewall log data received per day by Firewall
Analyzer.

| 2000/sec or 60 GB/day |

CPU Requirements
- Dedicated machine has to be allocated to process more than 200 logs per second.
- Dual core processors are needed to process more than 500 logs per second.
- Quadra core processors are needed to process more than 1000 logs second.
RAM Requirements
- Number of firewalls handled by the Firewall Analyzer will increase the requirement of the above RAM values. So it is better to have RAM value higher than the suggested value in case of having more than 5 firewalls.
Separate Installation
- Firewall Analyzer server and MySQL database can be installed in separate machines, in case of higher log rate with low-end CPU machines.
Hard Disk Requirements for more months
- The above Hard Disk space requirement projected is for one month. If you need to archive the logs for more number of months, multiply the above requirements with the number of months based on your requirement.
Note: The Log Records Per Second is the
total log records received per second by Firewall Analyzer
from all the configured devices.
For better performance, we recommend replacing the existing
MySQL parameters mentioned in startDB.bat/sh,
available under <FirewallAnalyzerHome>\bin directory,
with the following MySQL parameters changes
for the corresponding RAM Size. Apart from MySQL parameter changes, you can also tune MySQL table sizes based on RAM availabililty to improve MySQL performance.

How to tune MySQL table sizes based on RAM availabililty?
In addition to MySQL parameter changes, one needs to change the "BATCH_SIZE" used for moving the data from and to report tables. To configure the BATCH_SIZE, follow the below mentioned steps,
1. Login to FWA Web-Client.
2. Type in the following URL, "http://<Name/IP of m/c in which FWA is installed>:8500/fw/dmConfig.do". 8500 is default web-server port.
3. This will show the current "BATCH_SIZE" configured by default.
4. Based on the RAM available in the machine, please configure the parameters and click on "Save Changes" button.
| RAM Size |
Batch Size Recommended |
| 1 GB |
Raw Table = 20000
Hourly Table = 30000 |
| 2 GB |
Raw Table = 30000
Hourly Table = 40000 |
| Above 2 GB |
Raw Table = 50000
Hourly Table = 40000 |
Firewall Analyzer can be installed and run on the following
operating systems and versions:
- Windows™ NT, 2000, XP & Vista and Windows™ 2003 & 2008 Servers
- Linux - RedHat 8.0/9.0, Mandrake/Mandriva, SuSE, Fedora, CentOS
Note: If Firewall Analyzer is installed
in SuSE Linux, then ensure that in the mysql-ds.xml
file, present under <FirewallAnalyzer_Home>/server/default/deploy
you replace localhost mentioned in the following
line : <connection-url>jdbc:mysql://localhost:33336/firewall</connection-url>
with the corresponding IP Address or DNS resolvable name of
the current system where Firewall Analyzer is installed.
- Internet Explorer 5.5 and later
- Netscape 7.0 and later
- Mozilla 1.5 and later
- Firefox 1.0 and later
