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
Java-generated tracks in these files are set to GMT.
As a result, in France, which is in the Europe/Paris time zone, times are +1h in the winter and +2h in the summer. To find items that took place at 15:00, you need to look for:
- 14:00 from late October to late March
- 13:00 from late March to late October
- internal service logs, managed by each service's configuration.
Storage time depends on each log administration mechanism's settings. These settings can be changed to the desired storage time.

|Synchronisation EAS||bm-eas||./bm-eas/eas.log||LogBack||Tracks operations carried out to and from mobile devices connected through EAS.|
In addition, logs for each synchronization file are stored in separate files, which makes the analysis of bugs or erroneous behavior easier.
Service that delivers emails to the corresponding mailbox.Some BlueMind-related operations are carried out here - ICS invitation analysis, for example.
|LogBack||Locate user-specific services (mailbox server, etc.)|
Service that allows the BM-Core server to run system operations on the BlueMind architecture nodes.

|Milter||bm-milter||./bm-milter/milter.log||LogBack||SMTP analysis and modification of emails.|
Instant messaging logs.
Service that allows Postfix or Cyrus to obtain or verify data with BlueMind:
PostgreSQL database logs.
This component's configuration can be edited using the file /etc/postgresql/9.6/main/postgresql.conf.local
The NGinx services allows HTTP and HTTPs access to BlueMind.
By default, configuration files are located in the directory
To edit them, copy the file you want to edit into
/etc/bm/local and edit the copy.
In the example above, the main log file core.log can keep 20 log files of 60Mb each at the most.
