This repository contains a simple Infinispan server-side task that scans the data container of a single node and creates a histogram of lifespans and maxidle times for all entries. The histogram is then output in the server log in the EXPIRATIONS category.
mvn clean package -Dversion.infinispan=<version>
Once built, the target directory will contain two jars:
expiration-dumper-task.jar - the server task which should be deployed on the server (standalone/deployments for Infinispan 8 and 9 or server/lib for Infinispan 10 or newer)
expiration-dumper.jar - the client that invokes the task. Invoke it as follows: java -jar expiration-dumper.jar <host> <port> <cachename> com.redhat.datagrid.TaskExecutor
