The splunk-library-javalogging artifact can be accessed via Splunk's managed Maven repoitory. These frameworks require:įor more information about installing and using Splunk logging for Java, seeįor all things developer with Splunk, see theįor more about about Splunk in general, see For more about logging framework requirements, see Enable logging to HEC and Enable logging to TCP inputs. If you're using the Log4j 2, Simple Logging Facade for Java (SLF4J), or Logback logging frameworks in conjunction with Splunk logging for Java there are additional compatibility requirements. You'll need Java version 8 or higher, from OpenJDK or Oracle. Splunk logging for Java is tested with Splunk Enterprise 8.0 and 8.2.0. Splunk and system requirements, see Installing & Running Splunk. If you haven't already installed Splunk, download it Here's what you need to get going with Splunk logging for Java. Support for batching events (sent to HTTP Event Collector only). Handler classes that export the logging events.Īn optional error handler to catch failures for HTTP Event Collector events.Įxample configuration files for all three frameworks that show how to configure the frameworks to write to HTTP Event Collector or TCP ports. Splunk logging for Java is also enabled for Simple Logging Facade for Java (SLF4J).Īppender classes that package events into the proper format for the input type you're using (HTTP Event Collector or TCP). You can use three major Java logging frameworks: Logback, Log4j 2, and. Splunk logging for Java enables you to log events to HTTP Event Collector or to a TCP input on a Splunk Enterprise instance within your Java applications. Anyone know of a reason why not to monitor all the rotated log files too? I know there are some advantages to monitoring a single file vs a directory like this, but I've never observed any performance impact from it.įor anyone interested, there are some additional source renaming examples here. I've found this kind of setup to work well. TRANSFORMS-rename_source = drop_trailing_digit ) when they are all originally from a single log file, so I use a transformer to renaming them back to the original server.log name. Especially, in scenarios where you can't afford to drop and events.Īlso, I don't like seeing multiple sources in this kind of scenario (e.g. And since splunk automatically recognizes rotated log files (and therefore will only indexed the previously unread portions of the log file), to me it can make sense to monitor all of the log files at once. In general, Splunk does a really good job a keeping up with log files but there are a few scenarios that just aren't covered. Let me throw in one more scenario, say server.log rotates to +1 at the same time as when splunkd is down due to a configuration change.
