Where Can I Find the Consolidation Server Logs?
The log file is located in: <DATADIR>\run\consolidationserver-<instance name>\.
You can also view logs in the Administration Console > Logs menu.
These logs contain the Consolidation Server process logs, and all the logs emitted by the transformation and aggregation processors.
You can use a log function for debugging your processors, as in the following sample:
process("Foo") {
// log the content of the processed node
log.info it
}
