    Study Notes

    Collector Functions and Processes

    • Collectors run event collection, compression, and upload processes.
    • Collectors perform data enrichment, compression, and upload to the supervisor or worker.

    Data Upload and Compression

    • Collectors upload data to the supervisor or worker every 1 minute (default upload frequency).
    • The compression ratio achieved by the collector is 10:1.
    • The algorithm used for data compression in FortiSIEM is gzip.

    Event Enrichment and Buffering

    • The local collector enriches each event with the organization ID and organization name.
    • The collector buffers events in files, with a maximum of 10,000 event files.
    • The total buffer storage on the collector is approximately 30 GB (calculated based on a default bytes per second rate of 2 MBPS).
    • The estimated average event size is 1,500 bytes.
    • It takes around 4 hours for the collector to reach the maximum buffer size for a 2000 EPS license.

    Collector Registration and Deployment

    • The collector registration process requires the organization ID, organization name, and other necessary information.
    • The initial state of a collector when it is deployed is inactive.
    • If the buffer on the collector is full, it stops receiving events until the buffer is cleared.

    Network Connection and Log Shipping

    • If the network connection to the supervisor or worker is not available, the collector buffers events until the connection is restored.
    • When the network connection becomes available again, the collector ships logs every 1 minute.
    • The purpose of having a collector in your environment is to collect, compress, and upload events to the supervisor or worker, and to provide event enrichment and buffering capabilities.
