Error Report Tool (ERTool)

ERTool is a java package for data analysis which simplifies processing large data-sets. This primarily focuses on the multipart-data obtained in a DataPower Error Report (.txt.gz), MQ Appliance (txt.gz) through Analytics.xml. Additionally supports Cast Iron/API Management (.tar.gz formatted files/directory lists) through postmortem.xml.

Prerequisites

JDK 1.7 or later
Apache Ant (Tested with 1.9.6, but likely work with 1.8.1 or later)

Building

After you obtain the source either via a Git client or by downloading the repository zip file, you can build the code using Apache Ant. Enter the framework directory and issue the command below (assumes Apache Ant is in the path):

ant -buildfile build.xml

The ErrorReport.jar will be found in dist/.

Running

For GUI:

java -jar ErrorReport.jar -gui

Special note regarding running the GUI on macOS: You will need to specify -XstartOnFirstThread in the vmargs:

java -XstartOnFirstThread -jar ErrorReport.jar -gui

For Text/CLI with no logging:

java -jar ErrorReport.jar -file "error-report.txt.gz" -analyticsfile Analytics.xml -loglevel none 1> "destinationfile.txt"

For Text/CLI with logging:

java -jar ErrorReport.jar -file "error-report.txt.gz" -analyticsfile Analytics.xml -loglevel info -outfile "destinationfile.txt"

In the CLI the -format HTML argument can be used to generate an HTML report to the destination file.

If ErrorReport.jar runs out of memory, increase the available JVM by adding -Xmx8096m as an argument to java.
If Stack Overflow Exceptions occur increase the stack size of the JVM by adding -Xss8m as an argument to java.
In cases of Stack Overflow some formulas will require large stack sizes, in testing some have required 512M for 100K lines parsed in regular expressions.
The loglevel argument can be set to none|info|debug to provide more information when testing formulas.
