General

In the General tab you decide how log entries will be saved.

logging_general

Field	Description
Enable file logging	Check this option to write log entries to text files.
Delete logs older than (Days)	By default, a new log file is created on a daily basis. This option allows you to delete old log files by specifying a threshold in days. In the screenshot above logs over 7 days old are deleted automatically. A value of zero here means the logs should never be deleted.
Archive deleted logs to file	Check this option and specify a fully qualified path to a file (ZIP or, older versions, MCB) where deleted logs will be archived. NOTE: Specifying just a folder name here could cause any files in that folder to be deleted.
Log file cache	Here you can specify an amount of memory to be used as a cache for logs. Log entries are written to the cache until the cache is full, at which point the cache is written and the cache cleared. A value of 0 specifies that no cache is used.
Rotate log files when size exceeds	On a very busy server with a high level of logging the daily log files could become too large to be readable. If you specify a number here then the logs will be rotated when the file reaches that size. In the above screenshot files will be rotated when they reach 70MB in size.
Logs	Press this button to access the Status – Logs node of IceWarp Server immediately.

Log files are saved in the <InstallDirectory>/logs directory or a subdirectory thereof:

Saved in <InstallDirectory>\logs directory with a filename ayyyymmdd-nn.log, are

a - is one of

c - for Web/Control Service

e - for general errors (including DB errors)

f - for FTP Service

g - for GroupWare Service

m - for IMAP Service

p - for POP3 Service

s - for SMTP Service

yyyy - is the year

mm - is the month (2 digits)

dd - is the day (2 digits)

nn - is a two digit incremental value, starting at 00, used if the log rotates within a one day period

logging_syslog

Field

Description

Send logs to system log function (syslog)

You can check this option to have all logged events sent to the system log.

Events are written using the C_System_Logging_General_SystemLogFunction Windows API function.

Send logs to server (syslog protocol)

Check this option to have the syslog sender send its data to an external (remote) syslog server.

This is usually used in large multi-server installations where there is a centralized syslog repository.

Information packets are sent over UDP using the system log call function.

logging_database

Field	Description
Active	Tick the box to have the log data sent to any database.
Settings	Press the button to setup the database connection.

NOTE: The use of a database to store log entries is not recommended as this can have a serious impact on server performance.

Please note that when using database logging the log entries cannot be displayed in Status - Logs.

You must extract these entries from the database if you wish to examine them.
