The Diagnostics page includes these tabs:
From the Diagnostics File tab, you can download a diagnostic log file (support.tgz) that includes packet trace information about your Firebox. For more information about how to download a diagnostic file, see Download a Diagnostic Log Message File in Fireware Web UI.
If fault events have occurred on your Firebox, you can see and manage the Fault Reports. For more information about Fault Reports, see Manage Fault Reports.
You can use the Network tab to find diagnostic information for your Firebox. You can ping the source or destination IP address, trace the route to the source or destination IP address, look up DNS information for an IP address, or see information about the packets transmitted across your network (TCP dump). You can also include arguments in your task details to narrow the results.
For information about how to run diagnostic tasks, see Run Diagnostic Tasks on Your Firebox.
From the VPN tab, you can run a VPN Diagnostic Report to see configuration and status information for a VPN gateway and the associated Branch Office VPN tunnels.

To verify the integrity of files and directories on your Firebox, you can run an on-demand integrity check from the System Integrity tab.
