![]() ![]() The shorthand pattern pattern="common" corresponds to the Common Log Format defined by ‘%h %l %u %t “%r” %s %b’. Any timestamps configured using an explicit SimpleDateFormat pattern ( %t tokens to the pattern, one can also log both timestamps. The locale used to format timestamps in the access log lines. Default value: use the system default character set. An empty string means to use the system default character set. See below for more information on configuring this attribute.Ĭharacter set used to write the log file. Default value: falseĪ formatting layout identifying the various information fields from the request and response to be logged, or the word commonor combined to select a standard format. This is similar to the behavior of most log frameworks when doing time based rotation. Only during rotation the file is closed and then renamed to include the timestamp. When setting renameOnRotateto true, the timestamp is no longer part of the active log file name. During rotation the file is closed and a new file with the next timestamp in the name is created and used. Default value: trueīy default for a rotatable log the active access log file name will contain the current timestamp in fileDateFormat. If set to false, then this file is never rotated and fileDateFormat is ignored. The date format will always be localized using the locale en_US.įlag to determine if log rotation should occur. If you wish to rotate every hour, then set this value to yyyy-MM-dd.HH. The file is rotated whenever the formatted timestamp changes. If not specified, the default value is “” (a zero-length string), meaning that no suffix will be added.Īllows a customized timestamp in the access log file name. The suffix added to the end of each log file’s name. If not specified, the default value is “access_log.”. The prefix added to the start of each log file’s name. If no directory attribute is specified, the default value is “logs” (relative to $CATALINA_BASE). If a relative path is specified, it is interpreted as relative to $CATALINA_BASE. This MUST be set to .AccessLogValve to use the default access log valve.Ībsolute or relative pathname of a directory in which log files created by this valve will be placed. Java class name of the implementation to use. The Access Log Valve supports the following configuration attributes: Attribute This Valve does not use Apache Commons Logging, thus avoiding additional overhead and potentially complex configuration). (The essential requirement for access logging is to handle a large continuous stream of data with low overhead. This Valve uses self-contained logic to write its log files, which can be automatically rolled over at midnight each day. These logs can later be analyzed by standard log analysis tools to track page hit counts, user session activity, and so on. The Access Log Valve creates log files in the same format as those created by standard web servers. Individual Valves have distinct processing capabilities, and are described individually below.
