Special Notices
This section highlights some of the operational changes that administrators should be aware of in FortiAnalyzer version 7.0.0.
FortiAnalyzer 7.2.3 and later firmware on FortiGuard
Starting in FortiAnalyzer 7.2.1, a setup wizard executes to prompt the user for various configuration steps and registration with FortiCare. During the execution, the FortiAnalyzer unit attempts to communicate with FortiGuard for a list of FortiAnalyzer firmware images currently available on FortiGuard – older and newer.
In the case of FortiAnalyzer 7.2.2, a bug in the GUI prevents the wizard from completing and prevents the user from accessing the FortiAnalyzer unit. The issue has been fixed in 7.2.3 and later and a CLI command has been added to bypass the setup wizard at login time.
config system admin setting
set firmware-upgrade-check disable
end
Fortinet has not uploaded FortiAnalyzer 7.2.3 and later firmware to FortiGuard in order to work around the GUI bug, however, the firmware is available for download from the Fortinet Support web site https://support.fortinet.com.
Hyperscale firewall mode
FortiAnalyzer does not support logs from the following models when they have hyperscale firewall mode and netflow enabled:
- FortiGate-1800F
- FortiGate-1801F
- FortiGate-2600F
- FortiGate-2601F
- FortiGate-4200F
- FortiGate-4201F
- FortiGate-4400F
- FortiGate-4401F
FortiAnalyzer only supports logs when the normal firewall mode with standard FortiGate logging are enabled.
Citrix XenServer default limits and upgrade
Citrix XenServer limits ramdisk to 128M by default. However the FAZ-VM64-XEN image is larger than 128M. Before updating to FortiAnalyzer 6.4, increase the size of the ramdisk setting on Citrix XenServer.
To increase the size of the ramdisk setting:
- On Citrix XenServer, run the following command:
xenstore-write /mh/limits/pv-ramdisk-max-size 536,870,912
- Confirm the setting is in effect by running
xenstore-ls.-----------------------
limits = ""
pv-kernel-max-size = "33554432"
pv-ramdisk-max-size = "536,870,912"
boot-time = ""
---------------------------
- Remove the pending files left in
/run/xen/pygrub.
|
The ramdisk setting returns to the default value after rebooting. |
FortiAnalyzer VM upgrade requires more memory
When upgrading FortiAnalyzer VM units from FortiAnalyzer 6.2.x to FortiAnalyzer 6.4.0 and later, the upgrade may fail because of memory allocation.
Workaround: Before upgrading FortiAnalyzer VM to FortiAnalyzer 6.4.0 and later, change the memory allocation to 8 GB of RAM.
Maximum ADOM limits for FortiAnalyzer
FortiAnalyzer hardware devices and VMs display a warning when the maximum number of ADOMs is reached or exceeded. The platform does not enforce the limit; however, adding more ADOMs may affect the performance of the unit. For more details, see Appendix A - Default and maximum number of ADOMs supported.
Port 8443 reserved
Port 8443 is reserved for https-logging from FortiClient EMS for Chromebooks.
Hyper-V FortiAnalyzer-VM running on an AMD CPU
A Hyper-V FAZ-VM running on a PC with an AMD CPU may experience a kernel panic. Fortinet recommends running VMs on an Intel-based PC.
SSLv3 on FortiAnalyzer-VM64-AWS
Due to known vulnerabilities in the SSLv3 protocol, FortiAnalyzer-VM64-AWS only enables TLSv1 by default. All other models enable both TLSv1 and SSLv3. If you wish to disable SSLv3 support, please run:
config system global
set ssl-protocol t1sv1
end
