Every time a device checks in with the Surveyor server, a 128-byte line is generated in the IIS log file. This log file records data for every device that checks in, every time the device checks in.
The lower the check-in interval time, the greater the amount of log data that will be generated on a daily basis (128 bytes of data x # of devices x # of times devices are checking in per hour).
To reduce the amount of data being logged, set the check-in interval to a higher number of minutes.
To modify the check-in interval, on the Configure menu , click System Settings.
