tkit-quarkus-log

1000kit Quarkus logger extension

RequestDataContext object move to the tkit-quarkus-context library

The version 1.0.0+ contains new package structure. For an old version please use branch 0.9.

Maven configuration

• tkit-quarkus-log-cdi - core log library for Quarkus ARC cdi implementation.
• tkit-quarkus-log-rs - log interceptor for jaxrs rest service endpoint.
• tkit-quarkus-log-json - advanced JSON formatter for the log.

The interceptor for the logger will be activated automatically.

Custom log entry for the parameter

@LogParam(classes = {AmqpMessage.class})
public static String logAmqpMessage(Object message) {
    AmqpMessage a = (AmqpMessage) message;
    return "AmqpMessage[" + a.getMessageId() + "," + a.getDeliveryCount() + "]";
}

The @LogParam annotation has this parameter:

• classes - the parameter will be use for these classes.
• assignableFrom - the parameter will be use for all assignable classes.
• priority - the priority of this logger parameter.

To exclude the parameter from the log you can use the annotation @LogExclude. There is a parameter mask is not set the parameter name will be written in the log. If you specified the value for the parameter mask it will be the value written in the log.

Configuration

Only the defined packages in the configuration will be add to the interceptor (default: org.tkit) For example:

tkit.log.packages=org.tkit
tkit.log.packages=com.acme

Method start and succeed log format

To configure the message format of the start, succeed, failed and future you can use these properties:

• tkit.log.result.void - text for the result void type. Default: void
• tkit.log.start - message format for the method start log. Default: {0}({1}) started.
• tkit.log.succeed - message format for the method succeed log. Default: {0}({1}):{2} [{3}s] succeed.
• tkit.log.failed - message format for the failed method log. Default: {0}({1}):{2} [{3}s] failed.
• tkit.log.futureStart - message format for the future return type method. Default: {0}({1}) future started.

REST service configuration

The logs of the rest endpoint could you configure with these variables:

• tkit.log.rs.start - rest endpoint start log. Default: {0} {1} [{2}] started.
• tkit.log.rs.succeed - rest endpoint end log. Default: {0} {1} [{2}s] finished [{3}-{4},{5}].
• tkit.log.rs.mdc - log rest endpoint information to the log as MDC keys.
• tkit.log.rs.disable - disable rest endpoint log.
• tkit.log.rs.header - comma separated list of header_key=log_mdc_key

REST client configuration

For the rest client you can configure these variables:

• tkit.log.rs.client.start - rest client start log. Default: {0} {1} [{2}] started.
• tkit.log.rs.client.succeed - rest client end log. Default: {0} {1} finished in [{2}s] with [{3}-{4},{5}].
• tkit.log.rs.client.mdc - log rest client information to the log as MDC keys.
• tkit.log.rs.client.disable - disable rest client log.
• tkit.log.rs.client.header - comma separated list of header_key=log_mdc_key

JSON configuration

JSON formatter configuration:

• quarkus.tkit.log.console.json - enable or disable the JSON formatter.
• quarkus.tkit.log.console.json.keys.mdc - comma separated list of mapping mdc_key=root_key.
• quarkus.tkit.log.console.json.keys.group - comma separated list of MDC group prefix and root keymdc_prefix=root_key. Group all MDC keys with a prefix.
• quarkus.tkit.log.console.json.keys.ignore - ignore key.
• quarkus.tkit.log.console.json.keys.type - comma separated list of key and type key=long. Types are int,long and double.
• quarkus.tkit.log.console.json.keys.env - comma separated list of mapping key=env_variable
• quarkus.tkit.log.console.json.splitStacktracesAfter - split messages with stacktraces after N characters. Only works with formatted exception output type
• quarkus.tkit.log.console.json.exception-output-type - how should the exceptions be formatted: detailed = stacktrace is serialized to json array, formatted = similar to standard output of exception logs(with tabs and formatting)

Configuration of external libraries

To configure external libraries you can use this configuration pattern for method level ./tkit-log/trace=true|false ./tkit-log/log=true|false

or for the class level: /tkit-log/trace=true|false /tkit-log/log=true|false

For example: org.tkit.test.Service.start/tkit-log/log=false org.tkit.test.Service/tkit-log/log=false

The trace attribute will printout the stacktrace of the exception in the interceptor.

Stack trace logging - configuration

• LogFriendlyException - interface for handling special exception logging, implement to configure if stack trace should be printed or not
• quarkus.tkit.log.mdc.errorKey - MDC key for FBN error number
• quarkus.tkit.log.customdata.prefix - MDC key for business data
