I have a common logging library integrated with log4j which is being used
by different packages/classes. I want a custom messageid in the log entry
so that filtering is easy. At the same time I want structured data fields
to be a part of configuration. For ex:
*<180>1 2015-02-12T00:04:57:627Z 10.1.1.2 - - HTTP [ id@68146
comp="manager” subcomp=“web" ] Received an HTTP request.*
* <180>1 2015-02-12T00:04:57:627Z 10.1.1.2 - - RPC [ id@68146
comp="manager” subcomp=“web"] Received an RPC request.*
The messageid will be passed as part of logger constructor based on the log
message content (logger constructor modified to do so) but the structured
data fields are common that can be provided in the configuration using MDC
but it doesn't work since I need messageid to be custom I am forced to use
StructuredDataMessage (see below). Currently I am passing the structured
data fields and the messageid as part of the message itself, see code below:
private Message format(final String pattern, final Object... arguments) {
String msg = arguments != null ?
Utils.formatAsLogSFPattern(pattern, arguments) : pattern;
Map<String, String> m = new HashMap<String, String>();
m.put("comp", *this.comp*); *//messageid, comp and subcomp is
received as part of logger constructor*
m.put("subcomp",* this.subcomp*);
return new *StructuredDataMessage*("nsx", msg,* this.messageId, m*);
}
public void fatal(String format, Object... args) {
if (log4jLogger.isEnabled(Level.FATAL)) {
log4jLogger.logIfEnabled(FQCN, Level.FATAL, null,
format(format, args), null);
}
}
If I remove the map implementation and pass NULL then I get 2 structured
data fields in the log.
