Summary
Troubleshooting web browsing performance issue can be very time-consuming because it can be affected by several factors, such as DNS, web server performance, URL Rating server connection, and LDAP query.
The connectivity test tool helps the IWSVA administrators to easily identify the areas that take a long time to produce results, or the areas where failures are encountered.
Details
To use the Connectivity Test tool:
- Log in to IWSVA shell as root.
- Go to the usr/iwss/connectivity_test directory and execute the following command:
./connectivitytest.sh
This command produces output like below:
