Configuration
If you have a FortiGate 30E device that comes with a GPS antenna, you can enable this option to get accurate location
information if GPS signal is good where the device is deployed.
The GPS module in the latest FortiGate 30E-GBL does not work because the device does not
have a GPS connector. For this reason, this option is set to disabled by default.
set data-usage-tracking
FortiWiFi-40F-3G4G (lte-modem) # set data-usage-tracking
enable Enable data usage tracking.
disable Disable data usage tracking.
The modem data usage in a resolution of 1min/10min/30min/hour/day is kept in the system if data-usage-tracking is
enabled. This option is disabled by default. A daily bytes in/bytes out record is kept in the flash file system for the past
60 days, and only records with higher resolution are kept in the memory file system. The system is designed to work in
this way because the size of flash memory in FortiGate 30E is limited.
Once data-usage-tracking is enabled in the system, it reads data in and out from the modem once every minute and
stores it in the memory file system. In the first record, the data usage is always set to 0, so it starts counting from the
second record. If the minute can be divided exactly by 10, a 10 min usage record is saved, so on for 30 min and hourly
data. If it is the first minute past midnight, a daily record is saved in the flash file system. The system only keeps a
certain maximum number of records for the same type and discards older records. The data-usage-tracking feature can
only give an approximate estimation, so it is not accurate. If the device is powered off in the middle of the day, you could
lose up to one day's worth of usage data.
set billing-date
FortiWiFi-40F-3G4G (lte-modem) # set billing-date
billing-date Enter an integer value from <1> to <31> (default = <1>).
Once data-usage-tracking is enabled, the billing-date option shows up. Billing date means the day of the month when a
new statement is generated. A billing cycle means the time frame starts from the last billing day till midnight of the day
before the next billing day. In the case 29~31 is set as the billing date, if days in the current month is less than the billing
date, the last day of the current month is used, if days in the previous month was less than the billing date, the billing
cycle is counted from the first day of the current month. The default billing date is 1.
set data-limit
FortiWiFi-40F-3G4G (lte-modem) # set data-limit
data-limit Enter an integer value from <0> to <100000>.
If data-usage-tracking is enabled, data-limit ranging from 1 MB to 100 GB can be set in the system. The default is 0
which means no limit. It can be used as a reminder of how much data you can use in a month. In the future, we can
generate an alarm to notify the users that their data limit is approaching.
