ESPER - how to create a context

I'm using ESPER 5.1.0 in java to run analysis on log events (sender, message). I want to look for certain message patterns for each single sender. I intend to do this by defining a context. I managed to create the EPContextPartitionAdmin but I do not understand how and where I need to create the actual context.

Is there something like .createEPL() for a context definition? Or am I missing a point here.

Solution

  • Yes a context is an EPL construct. You declare it via the "createEPL" API. For example:

    admin.createEPL("create context Every5Minute start @now end after 5 minutes");
