What does the insert vs receive rate graph illustrate in system settings?

The insert vs receive rate graph is a crucial monitoring tool within the system settings of FortiAnalyzer. This graph illustrates both the rate at which logs are being sent to the FortiAnalyzer and the rate at which these logs are being processed and indexed by the SQL database, managed by the sqlplugind daemon.

Understanding both aspects is essential for administrators. The insert rate represents the influx of log data into the system; this is important to track to ensure that the FortiAnalyzer can handle the volume of incoming data without performance issues. Conversely, the receive rate shows how effectively and quickly these logs are being indexed and made available for query, which is critical for maintaining operational efficiency and timely access to log data for analysis.

By capturing both metrics, the graph provides a complete view of data flow within FortiAnalyzer, allowing for better performance monitoring and troubleshooting. This dual-functionality is why the correct answer encompasses both the rate of log reception and the rate of log processing.
