Zoho Corp.

2. Firewall Analyzer displays "Port 8500 needed by Firewall Analyzer is being used

by another application. Please free the port and restart Firewall Analyzer" when

trying to start the server.

Probable cause: The default web server port used by Firewall Analyzer is not

free.

Solution: Kill the other application running on port 8500. If you cannot free this

port, then change the web server port used in Firewall Analyzer.

3. Unable to start the application in Linux

Probable cause: It is due to invalid host information in the etc/hosts directory.

Solution: Change it to the following format, you will be able to start the

application and get reports.

/etc/hosts

Entry should be like:

127.0.0.1 mini localhost

Importing Logs

1. Firewall Analyzer not importing logs from mapped network drive, if Firewall

Analyzer is running as service.

Solution: Instead of giving mapped network drive, you give UNC path

(\\ComputerName\SharedFolder\Resource) (e.g., \\cherry\log\isa_log*.w3c).

If the issue still persist, check the following:

• The account in which Firewall Analyzer service runs must have full

privilege to that shared drive

• If the Firewall Analyzer machine is in a domain xxxxx and the shared

machine/drive is in a workgroup (i.e., cross domain), Firewall Analyzer will

not fetch the logs unless the full domain admin privilege is available.

Reporting

1. Why am I seeing empty graphs?

Probable cause:Graphs are empty either because there is no traffic is passing

through the firewall or if firewall traffic is not sufficient enough to populate the

reports table of Firewall Analyzer.

Solution: If you are starting Firewall Analyzer for the first time or if you are

shutting down and restarting Firewall Analyzer, it will wait for the reports table to

be populated with 5000 log records for the first time. From the next time

onwards, Firewall Analyzer will populate reports table once in 7 minutes or once it

receives the next 5000 records, whichever is earlier. You can check for the

number of records received in " Packet Count " icon shown in top right corner in

client UI. This will list out the details like the number of logs received and also the

1 2 ... 265 266 267 268 269 270 271 272 273 274 275 ... 308 309
