![]() 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. Powershell -c iex ((New-Object ).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. Next, we going to start decoding the base64 strings.Īgain, press Ctrl + Arrow-Down to go end of column, and type the formula as below: Your Excel will look something like this: Then paste/ Ctrl + V to fill all column with string “ ASCII“. Then, press Ctrl + Shift + Arrow-Up to select from bottom to top. After that, type in string “ ASCII” in one of the row and copy it ( Ctrl-C). Just press Ctrl + Arrow-Down to quickly go to end/bottom of data column. Let’s say you have 300 row of data in your Excel, then fill 300 of “ ASCII” strings besides it. We need to fill up column “ ASCII” with string “ ASCII” until end/bottom of your data. Then, create 2 new column in the Excel sheet column named “ ASCII” and “ Decoded Base64“: Paste macro code given above inside the editor:Īfter that, close the editor window. Create new macro – you can give any name you want. To use it, first, we need to open the Splunk result that we exported earlier.Īfter that, press Alt-F8 to open the macro editor. TextBase64Encode = Replace(Replace(.Text, vbCr, ""), vbLf, "")įunction TextBase64Decode(strBase64, strCharset) With CreateObject("MSXML2.DOMDocument").createElement("tmp") The macro code that we’ll be using as below:įunction TextBase64Encode(strText, strCharset) MACRO) to automatically decode those base64 strings for us. ![]() So… We going to leverage Excel & macro (yes. ![]() How can I quickly decode all these base64 strings? We not gonna decode it one-by-one aren’t we? There are hundreds or probably thousand of it. If you decode the base64 from the example of raw event above: KGN1cmwgLXMgNDUuMTU1LjIwNS4yMzM6NTg3NC9YLlguWC5YOjQ0M3x8d2dldCAtcSAtTy0gNDUuMTU1LjIwNS4yMzM6NTg3NC9YLlguWC4xODo0NDMpfGJhc2g= The result after we export it from Splunk (opened in Excel) looks like: Using the Splunk query above, it will show you a table formatted data which contains extracted base64 under field named “ string“.
