Long-term monitoring of FortiGate total throughput

Question

Hello,

in order to plan the size of a new firewall, I would like to know the long-term throughput of my current firewall (in this case a 300E, 7.2.x).

I know there is the command "get system performance status" which shows the current and average throuput, but this is limited to the last 30 minutes. Also the interface bandwidth widgets on the dashboard do not help, because it is a device with multiple VDOMs and multiple connected interfaces. Therefore I would have to accumulate many different values.

My question is therefore, if there is any option, to monitor the long-term throughput on the device? This can also happen by SNMP. FortiAnalyzer and FortiManager are also available. The important information would be an average and the maximum total throughput, at least over one month.

Thank you in advance - Regards

Greetings!

To monitor the long-term throughput of your FortiGate 300E over one month, you can utilize FortiAnalyzer to gather historical data and analyze the average and maximum total throughput.

1. Utilize FortiAnalyzer:
- FortiAnalyzer can collect logs and traffic data from your FortiGate device over an extended period.
- Set up FortiAnalyzer to receive logs and traffic data from your FortiGate 300E.

2. Generate Reports:
- Create custom reports on FortiAnalyzer to analyze the throughput data over the desired timeframe (e.g., one month).
- Use the collected data to calculate the average and maximum total throughput.

3. Analyze Throughput Data:
- Review the reports generated by FortiAnalyzer to identify trends in throughput over the specified period.
- Calculate the average and maximum total throughput based on the historical data provided by FortiAnalyzer.

4. SNMP Monitoring:
- Additionally, you can set up SNMP monitoring on your FortiGate device to track throughput metrics continuously.
- Configure SNMP traps to send data to a monitoring system for long-term analysis.

By leveraging FortiAnalyzer for historical data collection and analysis, along with SNMP monitoring for real-time tracking, you can effectively monitor the long-term throughput of your FortiGate 300E and plan for the sizing of a new firewall based on accurate data.
