Technical Tip: How to calculate quota GB/Day and Disk entitled for FortiAnalyzer Cloud
Description
This article describes how to understand the quota GB/Day of logs and disk entitled from the subscription in FortiAnalyzer Cloud.
Scope
FortiAnalyzer Cloud.
Solution
FortiAnalyzer Cloud can be provisioned by getting a license either from Device Level or Account Level.
the device Level, each FortiGate can add an SKU for FortiAnalyzer Cloud subscription with or without SOCaaS. See: Licensing.
It can be reviewed in Support Portal -> Asset Management -> Products -> Product List -> FortiGate -> Select one FortiGate -> Entitlement -> Select the icon
.
 

Additional storage license or in-case does not purchase any Device Level subscriptions, Account Level can be reviewed under Support Portal -> Asset Management -> Account Services -> FortiAnalyzer Cloud.

If checking on Account Level and it does not show any information, that is expected since no additional SKU FCX-10-AZCLD-463-01-DD are purchased, and are supposed to be only on Device Level.
Note:
SKU FCX-10-AZCLD-463-01-DD also supports FortiMail and FortiClient logs.
 
Once all levels of subscriptions are confirmed, proceed to understand how to calculate quota GB/Day and disk entitlement.

For GB/Day daily rate of logging are depends on the FortiGate model:
| Specifications (Virtual Machine) | FortiGate Hardware Model | Total daily log limit |
| Desktop or FortiGate-VM models with 2 CPU | FortiGate 30 to FortiGate 90 | 200MB/Day |
| 1RU or FortiGate-VM models with 4 CPU | FortiGate 100 series, FortiGate 600 series, FortiGate 800 series, FortiGate 900 series | 1GB/Day |
| 2 RU and above or FortiGate-VM models with 8 CPU and above | FortiGate 1000 series and higher | 5GB/Day |
 
Check under Support Portal -> Asset Management -> Products -> Product List -> FortiGate for Device Level.

For Account Level, Support Portal -> Asset Management -> Account Services -> FortiAnalyzer Cloud

Total GB/Day is the combination of both Device Level and Account Level:
- 800 MB/Day +5 GB/Day = 5.8 GB/Day ~ round up to 6GB/Day
For entitled disk storage, the value for GB/Day times 100 Days for default Analytics retention.
- 5.8 GB/Day x 100 = 580GB
By default, FortiAnalyzer Cloud resources are provided with 6 vCPU, 16GB RAM, and 500GB disk despite the subscriptions entitled. Once it detects disk usage is more than 65%, the Cloud team will increase the storage size based on entitlement.
Check the current disk size using the command below:
FAZVM64-VIO-CLOUD # execute lvm info
LVM Status: OK
LVM Size: 500GB
File System: ext4 491GB
Disk1 : Used 500GB
Disk2 : Unavailable 0GB
