According to the log4j wiki : Note that TimeBasedRollingPolicy can only be configured with xml, not log4j. Improve this answer. Paul Paul This has been fixed a while ago, and log4j I have recently made a patch to allow for recursive subdirectories to be created automatically when using this combination: pastebin.

Eventually if you don't want to use extras You can workaround using: org. DailyRollingFileAppender Minus of this path is that your log files won't be gzipped. Worked with 2.

Connection lost. IOException", "message": "Connection lost. The name of the Appenders to invoke asynchronously. If true, the appender will wait until there are free slots in the queue. How many milliseconds the Appender should wait to flush outstanding log events in the queue on shutdown. Specifies the maximum number of events that can be queued. The name of the Appender to invoke if none of the appenders can be called, either due to errors in the appenders or because the queue is full.

A Filter to determine if the event should be handled by this Appender. The default is true, causing exceptions encountered while appending events to be internally logged and then ignored. Extracting location is an expensive operation it can make logging 5 - 20 times slower.

This element overrides what type of BlockingQueue to use. This is the default implementation that uses ArrayBlockingQueue. This uses the Conversant Disruptor implementation of BlockingQueue. This plugin takes a single optional attribute, spinPolicy, which corresponds to.

This uses the new in Java 7 implementation LinkedTransferQueue. Note that this queue does not use the bufferSize configuration attribute from AsyncAppender as LinkedTransferQueue does not support a maximum capacity. Whether or not to use batch statements to write log messages to Cassandra. By default, this is false. A list of column mapping configurations. Each column must specify a column name. Each column can have a conversion type specified by its fully qualified class name.

By default, the conversion type is String. If the configured type is assignment-compatible with java. Date, then the log timestamp will be converted to that configured date type. Otherwise, the layout or pattern specified will be converted into the configured type and stored in that column. A list of hosts and ports of Cassandra nodes to connect to. These must be valid hostnames or IP addresses.

By default, if a port is not specified for a host or it is set to 0, then the default Cassandra port of will be used. By default, localhost will be used. Whether or not to use the configured org. Clock as a TimestampGenerator. The Layout to use to format the LogEvent. Identifies whether the appender honors reassignments of System. Note that the follow attribute cannot be used with Jansi on Windows. Cannot be used with direct. Write directly to java.

FileDescriptor and bypass java. Can give up to 10x performance boost when the output is redirected to file or other process. Cannot be used with Jansi on Windows. Cannot be used with follow. Output will not respect java. When true - the default, records will be appended to the end of the file. When set to false, the file will be cleared before new records are written. When true - the default, records will be written to a buffer and the data will be written to disk when the buffer is full or, if immediateFlush is set, when the record is written.

File locking cannot be used with bufferedIO. The appender creates the file on-demand. The appender only creates the file when a log event passes all filters and is routed to this appender. Defaults to false. The name of the file to write to.

If the file, or any of its parent directories, do not exist, they will be created. This will significantly impact performance so should be used carefully. Furthermore, on many systems the file lock is "advisory" meaning that other applications can perform operations on the file without acquiring a lock. The default value is false. Examples: rw or rw-rw-rw- etc File owner to define whenever the file is created.

File group to define whenever the file is created. An array of Agents to which the logging events should be sent. If more than one agent is specified the first Agent will be the primary and subsequent Agents will be used in the order specified as secondaries should the primary Agent fail. Each Agent definition supplies the Agents host and port. The specification of agents and properties are mutually exclusive. If both are configured an error will result. The number of times the agent should be retried before failing to a secondary.

Specifies the number of events that should be sent as a batch. The default is 1. This parameter only applies to the Flume Appender. Directory where the Flume write ahead log should be written. Valid only when embedded is set to true and Agent elements are used instead of Property elements. The character string to prepend to each event attribute in order to distinguish it from MDC attributes.

The default is an empty string. Factory that generates the Flume events from Log4j events. The default factory is the FlumeAvroAppender itself. The default is 5. A comma separated list of mdc keys that should be excluded from the FlumeEvent.

This is mutually exclusive with the mdcIncludes attribute. A comma separated list of mdc keys that should be included in the FlumeEvent. Any keys in the MDC not found in the list will be excluded. This option is mutually exclusive with the mdcExcludes attribute. A comma separated list of mdc keys that must be present in the MDC. If a key is not present a LoggingException will be thrown.

A string that should be prepended to each MDC key in order to distinguish it from event attributes. The default string is "mdc:". When used to configure in Persistent mode the valid properties are: "keyProvider" to specify the name of the plugin to provide the secret key for encryption. One of "Avro", "Embedded", or "Persistent" to indicate which variation of the Appender is desired. If an integer greater than 0, this causes the appender to buffer log events and flush whenever the buffer reaches this size.

Information about the columns that log event data should be inserted into and how to insert that data. Clob or java. NClob, then the formatted event will be set as a Clob or NClob respectively similar to the traditional ColumnConfig plugin.

When set to true, log events will not wait to try to reconnect and will fail immediately if the JDBC resources are not available. New in 2. If set to a value greater than 0, after an error, the JDBCDatabaseManager will attempt to reconnect to the database after waiting the specified number of milliseconds. If the reconnect fails then an exception will be thrown which can be caught by the application if ignoreExceptions is set to false. The full, prefixed JNDI name that the javax. The DataSource must be backed by a connection pool; otherwise, logging will be very slow.

The fully qualified name of a class containing a static factory method for obtaining JDBC connections. The name of a static factory method for obtaining JDBC connections.

This method must have no parameters and its return type must be either java. Connection or DataSource. If the method returns Connections, it must obtain them from a connection pool and they will be returned to the pool when Log4j is done with them ; otherwise, logging will be very slow.

If the method returns a DataSource, the DataSource will only be retrieved once, and it must be backed by a connection pool for the same reasons. The JDBC driver class name. Defaults to example. You can use the JDBC connection string prefix jdbc:apache:commons:dbcp: followed by the pool name if you want to use a pooled connection elsewhere. For example: jdbc:apache:commons:dbcp:example.

Use this attribute to insert a value or values from the log event in this column using a PatternLayout pattern. Simply specify any legal pattern in this attribute. Use this attribute to insert the event timestamp in this column, which should be a SQL datetime. The value will be inserted as a java.

Either this attribute equal to true , pattern, or isEventTimestamp must be specified, but not more than one of these. This attribute is ignored unless pattern is specified. If true or omitted default , the value will be inserted as unicode setNString or setNClob. Otherwise, the value will be inserted non-unicode setString or setClob.

The name to locate in the Context that provides the ConnectionFactory. This can be any subinterface of ConnectionFactory as well. If a factoryName is specified without a providerURL a warning message will be logged as this is likely to cause problems. From Log4j 2. The name to use to locate the Destination. This can be a Queue or Topic, and as such, the attribute names queueBindingName and topicBindingName are aliases to maintain compatibility with the Log4j 2. If a securityPrincipalName is specified without securityCredentials a warning message will be logged as this is likely to cause problems.

When true, exceptions caught while appending events are internally logged and then ignored. When false exceptions are propagated to the caller. When set to true, log events will not wait to try to reconnect and will fail immediately if the JMS resources are not available. If set to a value greater than 0, after an error, the JMSManager will attempt to reconnect to the broker after waiting the specified number of milliseconds.

The name of the JPA persistence unit that should be used for persisting log events. Contains the configuration for the KeyStore and TrustStore for https. Optional, uses Java runtime defaults if not specified. See SSL. Whether to verify server hostname against certificate.

Only valid for https. Optional, defaults to true. The key that will be sent to Kafka with every message. Optional value defaulting to null. Any of the Lookups can be included. Required, there is no default. The default is true, causing sends to block until the record has been acknowledged by the Kafka server.

When set to false sends return immediately, allowing for lower latency and significantly higher throughput. Be aware that this is a new addition, and it has not been extensively tested. Any failure sending to Kafka will be reported as error to StatusLogger and the log event will be dropped the ignoreExceptions parameter will not be effective.

Log events may arrive out of order to the Kafka server. You can set properties in Kafka producer properties. You need to set the bootstrap.

Do not set the value. Log4j will round the specified value up to the nearest power of two. By default, the MongoDB provider inserts records with the instructions com. If you specify writeConcernConstant, you can use this attribute to specify a class other than com. WriteConcern to find the constant on to create your own custom instructions. To provide a connection to the MongoDB database, you can use this attribute and factoryMethodName to specify a class and static method to get the connection from.

The method must return a com. MongoDatabase or a com. If the com. MongoDatabase is not authenticated, you must also specify a username and password. If you use the factory method for providing a connection, you must not specify the databaseName, server, or port attributes. You must also specify a username and password. You can optionally also specify a server defaults to localhost , and a port defaults to the default MongoDB port. Enable support for capped collections.

Specify the size in bytes of the capped collection to use if enabled. The minimum size is bytes, and larger sizes will be increased to the nearest integer multiple of See the capped collection documentation linked above for more information. To provide a connection to the CouchDB database, you can use this attribute and factoryMethodName to specify a class and static method to get the connection from.

The method must return a org. CouchDbClient or a org. If you use the factory method for providing a connection, you must not specify the databaseName, protocol, server, port, username, or password attributes.

You can optionally also specify a protocol defaults to http , server defaults to localhost , and a port defaults to 80 for http and for https. Must either be "http" or "https. The name of the Appenders to call after the LogEvent has been manipulated. One of more Property elements to define the keys and values to be added to the ThreadContext Map.

The pattern of the file name of the archived log file. The format of the pattern is dependent on the RolloverPolicy that is used. The pattern also supports interpolation at runtime so any of the Lookups such as the DateLookup can be included in the pattern. The cron expression. The expression is the same as what is allowed in the Quartz scheduler.

See CronExpression for a full description of the expression. On startup the cron expression will be evaluated against the file's last modification timestamp. If the cron expression indicates a rollover should have occurred between that time and the current time the file will be immediately rolled over. The minimum size the file must have to roll over. A size of zero will cause a roll over no matter what the file size is. The default value is 1, which will prevent rolling over an empty file.

How often a rollover should occur based on the most specific time unit in the date pattern. For example, with a date pattern with hours as the most specific item and and increment of 4 rollovers would occur every 4 hours.

The default value is 1. Indicates whether the interval should be adjusted to cause the next rollover to occur on the interval boundary.

For example, if the item is hours, the current hour is 3 am and the interval is 4 then the first rollover will occur at 4 am and then next ones will occur at 8 am, noon, 4pm, etc. Indicates the maximum number of seconds to randomly delay a rollover. By default, this is 0 which indicates no delay. This setting is useful on servers where multiple applications are configured to rollover log files at the same time and can spread the load of doing so across time.

During the first rollover foo. A new foo. During the second rollover foo. During the third rollover foo. In the fourth and subsequent rollovers, foo During the second rollover foo During the third rollover foo If set to "max" the default , files with a higher index will be newer than files with a smaller index. If set to "min", file renaming and the counter will follow the Fixed Window strategy described above.

The maximum value of the counter. Once this values is reached older archives will be deleted on subsequent rollovers. The default value is 7. Only implemented for ZIP files. The maximum number of files to allow in the time period matching the file pattern.

If the number of files is exceeded the oldest file will be deleted. If specified, the value must be greater than 1. If the value is less than zero or omitted then the number of files will not be limited. The maximum number of levels of directories to visit. A value of 0 means that only the starting file the base path itself is visited, unless denied by the security manager.

A value of Integer. The default is 1, meaning only the files in the specified base directory. If true, files are not deleted but instead a message is printed to the status logger at INFO level. Use this to do a dry run to test if the configuration works as expected. Default is false. A plugin implementing the PathSorter interface to sort the files before selecting the files to delete.

The default is to sort most recently modified files first. Required if no ScriptCondition is specified. One or more PathCondition elements. Users can create custom conditions or use the built-in conditions: IfFileName - accepts files whose path relative to the base path matches a regular expression or a glob.

IfLastModified - accepts files that are as old as or older than the specified duration. IfAccumulatedFileCount - accepts paths after some count threshold is exceeded during the file tree walk. IfAccumulatedFileSize - accepts paths after the accumulated file size threshold is exceeded during the file tree walk. IfAll - accepts a path if all nested conditions accept it logical AND. Nested conditions may be evaluated in any order. IfAny - accepts a path if one of the nested conditions accept it logical OR.

IfNot - accepts a path if the nested condition does not accept it logical NOT. Required if regex not specified. Matches the relative path relative to the base path using a limited pattern language that resembles regular expressions but with a simpler syntax.

Required if glob not specified. Matches the relative path relative to the base path using a regular expression as defined by the Pattern class. An optional set of nested PathConditions. If any nested conditions exist they all need to accept the file before it is deleted. Nested conditions are only evaluated if the outer condition accepts a file if the path name matches. Specifies a duration. The condition accepts files that are as old or older than the specified duration.

Nested conditions are only evaluated if the outer condition accepts a file if the file is old enough. Nested conditions are only evaluated if the outer condition accepts a file if the threshold count has been exceeded. The threshold accumulated file size from which files will be deleted. Nested conditions are only evaluated if the outer condition accepts a file if the threshold accumulated file size has been exceeded.

The Script element that specifies the logic to be executed. The script is passed a list of paths found under the base path and must return the paths to delete as a java. The directory from where the Delete action started scanning for files to delete. Can be used to relativize the paths in the pathList. The list of paths found under the base path up to the specified max depth, sorted most recently modified files first.

The script is free to modify and return this list. File owner to define when action is executed. File group to define when action is executed. The format of the pattern should is dependent on the RolloverStrategu that is used. A Map shared between all script invocations for this appender instance. This is the same map passed to the Routes Script. If no layout is supplied HTML layout will be used. The name or address of the system that is listening for log events.

This parameter is required. When set to true, log events will not wait to try to reconnect and will fail immediately if the socket is not available. When true - the default, events are written to a buffer and the data will be written to the socket when the buffer is full or, if immediateFlush is set, when the record is written.

If set to a value greater than 0, after an error the SocketManager will attempt to reconnect to the server after waiting the specified number of milliseconds. The connect timeout in milliseconds. The default is 0 infinite timeout, like Socket. SSL if omitted. See also Standard names. Contains your private keys and certificates, and determines which authentication credentials to send to the remote host.
