The requirements described in this section must be fulfilled for the Qlik Sense logging to function properly.
Securing the file system
The system administrator must secure the file system so that the log files cannot be tampered with.
The nodes within a Qlik Sense site must have synchronized time.
For the date and time stamps to be correct, all nodes within a site must be configured to synchronize their system clocks with either an internal or an external Network Time Protocol (NTP) service to ensure that all log entries are time-stamped accurately. NTP is a networking protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks.
Setting time zone
It is recommended that every node within a Qlik Sense site is set to the correct time zone so that the time zone corresponds to the geographical location of the node.
