GELF message has empty mandatory "short_message" field
Hi, I'm using Graylog as logging platform and in the error logs I'm facing an issue related to the way Nxlog is forwarding messages to Graylog. Here the stacktrace followed by the nxlog configuration: 2021-10-19T17:00:24.464+02:00 ERROR [DecodingProcessor] Error processing message RawMessage{id=49ba6ee1-30ed-11ec-a554-005056a17083, journalOffset=140463071838, codec=gelf, payloadSize=249, timestamp=2021-10-19T15:00:24.398Z, remoteAddress=/10.181.8.23:39018} java.lang.IllegalArgumentException: GELF message <49ba6ee1-30ed-11ec-a554-005056a17083> (received from <10.181.8.23:39018>) has empty mandatory "short_message" field. at org.graylog2.inputs.codecs.GelfCodec.validateGELFMessage(GelfCodec.java:258) ~[graylog.jar:?] at org.graylog2.inputs.codecs.GelfCodec.decode(GelfCodec.java:140) ~[graylog.jar:?] at org.graylog2.shared.buffers.processors.DecodingProcessor.processMessage(DecodingProcessor.java:149) ~[graylog.jar:?] at org.graylog2.shared.buffers.processors.DecodingProcessor.onEvent(DecodingProcessor.java:90) [graylog.jar:?] at org.graylog2.shared.buffers.processors.ProcessBufferProcessor.onEvent(ProcessBufferProcessor.java:90) [graylog.jar:?] at org.graylog2.shared.buffers.processors.ProcessBufferProcessor.onEvent(ProcessBufferProcessor.java:47) [graylog.jar:?] at com.lmax.disruptor.WorkProcessor.run(WorkProcessor.java:143) [graylog.jar:?] at com.codahale.metrics.InstrumentedThreadFactory$InstrumentedRunnable.run(InstrumentedThreadFactory.java:66) [graylog.jar:?] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_292] 2021-10-19T17:00:24.464+02:00 ERROR [DecodingProcessor] Unable to decode raw message RawMessage{id=49ba47dc-30ed-11ec-a554-005056a17083, journalOffset=140463071836, codec=gelf, payloadSize=249, timestamp=2021-10-19T15:00:24.397Z, remoteAddress=/10.181.8.23:39018} on input <581344a7a0474e1cf763f7f4>. 2021-10-19T17:00:24.469+02:00 ERROR [DecodingProcessor] Error processing message RawMessage{id=49bb3232-30ed-11ec-a554-005056a17083, journalOffset=140463071886, codec=gelf, payloadSize=249, timestamp=2021-10-19T15:00:24.403Z, remoteAddress=/10.181.8.23:39018} java.lang.IllegalArgumentException: GELF message <49bb3232-30ed-11ec-a554-005056a17083> (received from <10.181.8.23:39018>) has empty mandatory "short_message" field. at org.graylog2.inputs.codecs.GelfCodec.validateGELFMessage(GelfCodec.java:258) ~[graylog.jar:?] at org.graylog2.inputs.codecs.GelfCodec.decode(GelfCodec.java:140) ~[graylog.jar:?] at org.graylog2.shared.buffers.processors.DecodingProcessor.processMessage(DecodingProcessor.java:149) ~[graylog.jar:?] at org.graylog2.shared.buffers.processors.DecodingProcessor.onEvent(DecodingProcessor.java:90) [graylog.jar:?] at org.graylog2.shared.buffers.processors.ProcessBufferProcessor.onEvent(ProcessBufferProcessor.java:90) [graylog.jar:?] at org.graylog2.shared.buffers.processors.ProcessBufferProcessor.onEvent(ProcessBufferProcessor.java:47) [graylog.jar:?] at com.lmax.disruptor.WorkProcessor.run(WorkProcessor.java:143) [graylog.jar:?] at com.codahale.metrics.InstrumentedThreadFactory$InstrumentedRunnable.run(InstrumentedThreadFactory.java:66) [graylog.jar:?] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_292] @ define ROOT /usr/bin #define REGEX /^(?x)^[(?<EventTime>\d{4}-\d{2}-\d{2}\ \d{2}:\d{2}:\d{2}),\d{3}]/ define REGEX /(?x)^[(?<EventTime2>\d{4}-\d{2}-\d{2}\ \d{2}:\d{2}:\d{2}),\d{3}]\ (?<Severity>\S+)\ (?<Class>\S+)\ -\ (?<Message>[\s\S]+)/ define REGEX_CATALINA /(?x)^(?<EventTime>\d{2}-\w{3}-\d{4}\ \d{2}:\d{2}:\d{2}).\d{3}\ (?<Message>[\s\S]+) | (?x)^(?<EventTime2>\w{3}\ \w{3}\ \d{2}\ \d{2}:\d{2}:\d{2})\ (?<Message2>[\s\S]+)/ <Extension gelfExt> Module xm_gelf Avoid truncation of the short_message field to 64 characters.
