JarCastingOohLaLog Log4j Appender
Log 4j Appender for Oohlalog Cloud Logging Service will post log messages the OohLaLog using standard Log4J interfaces and configuration.
##Configuration
Please follow standard Log4J properties-based or XML-based configuration and include the following properties.
log4j.appender.oohlalog=com.oohlalog.log4j.OohLaLogAppender
log4j.appender.oohlalog.layout=org.apache.log4j.PatternLayout
log4j.appender.oohlalog.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
#Required: Replace with OohLaLog instance Api Key
log4j.appender.oohlalog.AuthToken=1234
#Optional: number logs to buffer before posting to OLL (lower numbers impact app performance)
#log4j.appender.oohlalog.MaxBuffer=100
#Optional: age of logs in buffer before automatic posting to OLL (lower numbers impact app performance)
#log4j.appender.oohlalog.TimeBuffer=5000
Replace AuthToken with the Api Key for your OohLaLog instance.
##Logging Context You may use the Logging Event NDC or the Logging Event MDCto set the logging context. This will set the OohLaLog log token that can be used to correllate log entries. For Example, you set the NDC to the remote user making an HTTP request.
org.apache.log4j.NDC.push(javax.servlet.http.HttpServletRequest.getRemoteUser());
or
org.apache.log4j.MDC.put("token",javax.servlet.http.HttpServletRequest.getRemoteUser()); // you must use the MDC key "token"
