OS journald configuration can lead to incorrect latency logging measurements #82

The "-latency_logging" option relies on journald logs but if journald is not configured in a specific manner the latency reporting will be incorrect. Documentation should be updated to indicate the required configuration. For example, on one particular system the following changes were needed to /etc/systemd/journald.conf

RateLimitInterval=0 RateLimitBurst=0

This disables rate control of journal messages.

Hi, Thank you for your input. Journal configuration has been added to the SDK documentation. Cheers,
