Server logging is not the same as auditing. Auditing logs activity on the IDM system, such as access, and synchronization. Server logging records information about the internal workings of IDM, like system messages, error reporting, service loading, or startup and shutdown messaging.
Configure server logging in your project’s
conf/logging.properties file. Changes to logging settings require a server restart before they take effect. Alternatively, use JMX via jconsole to change the logging settings. In this case, changes take effect without restarting the server.
The way IDM logs messages is set in the
handlers property in the
logging.properties file. This property has the following value by default:
The default handlers are:
FileHandlerwrites formatted log records to a single file or to a set of rotating log files. By default, log files are written to
ConsoleHandlerwrites formatted logs to
Additional log message handlers are listed in the
IDM supports the two default log formatters included with Java. These are set in the
java.util.logging.SimpleFormatter.formatoutputs a text log file that is human-readable. This is the default formatter.
java.util.logging.XMLFormatteroutputs logs as XML, for use in logging software that can read XML logs.
IDM extends the Java
SimpleFormatter with the following formatting options:
This is the default formatter for console and file logging. It extends the
SimpleFormatterto include the thread ID of the thread that generated each message. The thread ID helps with debugging when reviewing the logs.
In the following example log excerpt, the thread ID is
 May 23, 2018 10:30:26.959 AM org.forgerock.openidm.repo.opendj.impl.Activator start INFO: Registered bootstrap repository service  May 23, 2018 10:30:26.960 AM org.forgerock.openidm.repo.opendj.impl.Activator start INFO: DS bundle started
SanitizedThreadIdLogFormatteralso encodes all control characters (such as newline characters) using URL-encoding, to protect against log forgery. Control characters in stack traces are not encoded.
Similar to the
SanitizedThreadIdLogFormatter, but does not encode control characters. If you do not want to encode control characters in file and console log messages, edit the file and console handlers in
java.util.logging.FileHandler.formatter = org.forgerock.openidm.logger.ThreadIdLogFormatter java.util.logging.ConsoleHandler.formatter = org.forgerock.openidm.logger.ThreadIdLogFormatter
SimpleFormatter (and, by extension, the
ThreadIdLogFormatter) lets you customize what information to include in log messages, and how this information is laid out. By default, log messages include the date, time (down to the millisecond), log level, source of the message, and the message sent (including exceptions). To change the defaults, adjust the value of
java.util.logging.SimpleFormatter.format in your
file. For more information on how to customize the log message format, see the related Java documentation.
By default, IDM logs messages at the
INFO level. This logging level is specified with the following global property in
You can specify different separate logging levels for individual server features which override the global logging level. Set the log level, per package to one of the following:
SEVERE (highest value) WARNING INFO CONFIG FINE FINER FINEST (lowest value)
For example, the following setting decreases the messages logged by the embedded PostgreSQL database:
# reduce the logging of embedded postgres since it is very verbose ru.yandex.qatools.embed.postgresql.level = SEVERE
Set the log level to
OFF to disable logging completely (Disable Logs), or to
ALL to capture all possible log messages.
If you use
You can override the log level settings, per script, with the following setting:
For more information about using
logger functions in scripts, see Log Functions.
It is strongly recommended that you do not log messages at the
By default, IDM rotates log files when the size reaches 5 MB, and retains up to 5 files. All system and custom log messages are also written to these files. You can modify these limits in the following properties in the
file for your project:
# Limiting size of output file in bytes: java.util.logging.FileHandler.limit = 5242880 # Number of output files to cycle through, by appending an # integer to the base file name: java.util.logging.FileHandler.count = 5
There is currently no
If necessary, you can disable logs. For example, to disable
ConsoleHandler logging, make the following changes in your project’s
conf/logging.properties file before you start IDM.
java.util.logging.ConsoleHandler.level = OFF, and comment out other references to
ConsoleHandler, as shown in the following excerpt:
# ConsoleHandler: A simple handler for writing formatted records to System.err #handlers=java.util.logging.FileHandler, java.util.logging.ConsoleHandler handlers=java.util.logging.FileHandler ... # --- ConsoleHandler --- # Default: java.util.logging.ConsoleHandler.level = INFO java.util.logging.ConsoleHandler.level = OFF #java.util.logging.ConsoleHandler.formatter = ... #java.util.logging.ConsoleHandler.filter=...
