-====== Services ======
+===== Services =====
 It shows all services(daemons) in a system. The status can be either "Active" or "Inactive". The "Active" indicates the service is running and the "Inactive" indicates the service has been stopped. The "Update Date" is the last time the service was checked. The "Uptime" is the time of the service was started.
-==== Database ====
+===== System Integrity =====
-===== Main Database Variables =====
+This system performs a system integrity check once a day (every day at 1 AM) and displays the integrity check results. If any changes or damage occur in any of the operating files, an integrity error may be displayed, and in such cases, a system update is required. To immediately check system integrity, click the icon([[File:스크린샷 2023-08-09 오후 4.02.11.png|25px]]) on the system status, and within a few seconds, the check results will be displayed again. The image below shows the screen displayed when there are no compromised files and there are more than one compromised files each other.
 It shows some key information of the database global variables. If you click the "plus" icon beside the title(i.e. "Main Database Variables"), you can see the information.
 You may open an issue<ref>https://issue.basein.net</ref> when you think the database may have some problems. In such a case, you must include this information.
-===== Main Database Events =====

 Events are named database objects containing SQL statements that are to be executed at a later stage, either once off, or at regular intervals.<ref>https://mariadb.com/kb/en/events/</ref> Several events are running in the database of the imRAD system.

-==== Syslog ====

 The [[ImRAD services(daemons) | logexp]] service reads the Syslog<ref>https://en.wikipedia.org/wiki/Syslog</ref> in its system and saves them into the imRAD database. It shows such Syslog.<br>
