What is the check-in interval for sensors to the EDR server?
Environment
EDR Server: 7.5.0 and Higher
Resolution
Defined in /etc/cb/cb.conf.
SensorCheckinDelaySec=60
Additional Information
Default value is 60, setting lower can potentially overwhelm Datagrid, the in memory storage that handles multiple items in the product and communicates with the minions (if clustered)
Check-in adjustment does not affect event submission time.
Check-in's provide updated sensor vitals such as the last checkin time, event/binary queue, uptime, sensor health status. This information is not critical to have updated earlier than the default setting.
A sensor is considered offline when last checkin time reported is over 5 minutes by default.
