This section highlights some of the operational changes that administrators should be aware of in FortiAnalyzer version 6.4.2.
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.
- 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
limits = ""
pv-kernel-max-size = "33554432"
pv-ramdisk-max-size = "536,870,912"
boot-time = ""
- Remove the pending files left in
The ramdisk setting returns to the default value after rebooting.
FortiManager and FortiAnalyzer Cloud VMs do not currently support FortiGate 6.4.0. Cloud VM users should continue using FortiGate firmware 6.2 builds. Cloud platforms will be supported in a future 6.4 patch release.
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.
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 - Recommended maximum number of ADOMs supported.
Port 8443 is reserved for https-logging from FortiClient EMS for Chromebooks.
Prior to upgrading to FortiAnalyzer 6.2, make sure that all FortiGate devices are configured to use encryption when communicating with FortiAnalyzer. Starting with FortiAnalyzer 6.2.0, all OFTP communications must be encrypted.
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.
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
