"UTC") and a String called locale then Graylog can ingest different types of structured data -- both log messages and network traffic -- from sources and formats including: More important than data collection is how that data is organized to facilitate analysis. Plain Syslog Shortcomings: Limited to 1024 bytes No data types in structured Syslog Too many Syslog dialects to successfully parse all of them No compression Improvements on these issues make GELF a great choice for logging from within applications.
