Logs: What is "-- MARK --"






In the (/var/log/messages ou /var/log/syslog) folder of your system, you shall find lines similar to these: 

Nov  3 15:32:29 linux -- MARK --
Nov  3 15:52:29 linux -- MARK --
Nov  3 16:12:29 linux -- MARK --
Nov  3 16:32:29 linux -- MARK --
Nov  3 16:52:29 linux -- MARK --
Nov  3 17:12:29 linux -- MARK --
Nov  3 17:32:29 linux -- MARK --
Nov  3 17:52:29 linux -- MARK --
Nov  3 18:12:29 linux -- MARK --



These lines are generated automatically by the log daemon every 20 minutes to indicate that the system works properly. In case of crash or temporary unavailability of the system, analysis of these lines will determine roughly what time the incident took place and for how long!
