Logs
BlueMind keeps log files for each application and usage type.
It is important to provide for enough disk space to store log and archive files.
Space overload stops new information from being saved into log files and can lead to sluggish, and possibly blocked, services.
There are 3 types of log files:
-
system logs, which rely on log administration mechanisms (rsyslog + logrotate)
-
BlueMind's Java services log, which rely on LogBack
Track times
Traces generated by Java in these files are in GMT time.
In France, for example, in the Europe/Paris time zone, the hours are shifted by 1 hour in winter and 2 hours in summer. To search for events that took place at 3pm, search for :
- at 2 p.m. from late October to late March
- at 1 p.m. from late March to late October
-
logs internal to a service, managed via the configuration of this service
The length of retention depends on how these log management mechanisms are configured. Their configuration can be modified to obtain the desired retention time.
Log files
Log files are located in the /var/log file and its subfolders.
