This document describes how to modify the rate at which sensors are updated when an upgrade is requested (either through group-policy upgrade changes or for global update for OS X/Linux). Updating too many sensors at once can cause high network utilization and updates are throttled by default, but the rate can be modified to increase or decrease speed of sensor upgrades.
The rate at which sensors (any type) are upgraded is dictated by the following parameters in /etc/cb/cb.conf:
The SensorMaxUpgradeRate determines the maximum number of sensors that will be upgraded per hour.
SensorUpgradeRateMonitorInterval determines the interval length before the next batch of sensors can upgrade. A smaller interval will reduce the number of upgrades at once. By default, the interval is 5 minutes (300 seconds / 60 = 5 minutes).
With default settings, there can be up to 50 upgrades every 5 minutes.
