Zoho Corp.
Note:Once you assign the protocols, the reports will show the assigned protocols
and the newly assigned protocols under their appropriate protocol group only
from the assigned time. You will see the unassigned protocols in the reports
generated earlier to the assigned time.
If you find that the reports based on ports, please assign specific protocols to the
corresponding port numbers and create a custom report to view the details.
Checking the port numbers
1. Check the port number by clicking on Settings > Protocol Groups > Click
on the drop down menu against 'View by Group'and select the appropriate
protocol. This will show the protocol identifiers with port numbers.
2. You can also check the raw log in the folder <Firewall Analyzer
Home>\server\default\archive\<DNS(or)IP address\Hot> folder to know the
protocol type and port numbers (You can open the file using a notepad).
Reporting
General
1. Why am I seeing empty graphs?
Graphs are empty if no data is available. If you have started the server for the
first time, wait for at least one minute for graphs to be populated.
2. What are the types of report formats that I can generate?
Reports can be generated in HTML, CSV, and PDF formats. All reports are
generally viewed as HTML in the web browser, and then exported to CSV or PDF
format. However, reports that are scheduled to run automatically, or be emailed
automatically, are generated only as PDF files.
3. Are IP addresses automatically resolved?
IP addresses are automatically resolved by connecting to the network DNS
server.
4. Why are some traffic values shown as 0.0 MB or 0.00%?
Since Firewall Analyzer processes log files as and when they are received, traffic
values of 0.0MB or 0.0% may be displayed initially when the amount of traffic is
less than 10KB. In such a case, wait until more data is received to populate the
report tables.
5. What are the different formats in which reports can be exported?
Reports can be exported as PDF or CSV files. However, reports are emailed only
as PDF files.
6. Why do the intranet reports show zero results?
Verify if intranet's have been configured correctly. If you have specified IP
addresses that are not actually behind the firewall, you will get zero values in the
reports.
