Denis A. Magda commented on IGNITE-12880:
-

Nikolay, thanks for looking into that.

Setting {code:java} setPeriod(EXPORT_TIMEOUT){code} did the trick and I could 
start the node with the exporter enabled. However, I still don't see any logs 
printed even after setting {code:java}cfg.setMetricsLogFrequency(5000){code}.

Here is a simple code sample I'm playing with (please see ServerNodeStartup 
file):
https://github.com/gridgain/demos/tree/master/ignite-metrics-demo

What should I expect to see and do we really need two parameters (setPeriod and 
setMetricsLogFrequence) to control the behavior?  Also, I would advise us to 
set a default value of setPeriod to non-zero (like 1 minute) so that the 
feature works once an instance of LogExporter is passed into the 
IgniteConfiguration.

It seems you don't setup period for a LoggerSPI.

{code:java}
LogExporterSpi logSpi = new LogExporterSpi();

logSpi.setPeriod(EXPORT_TIMEOUT);
{code}

An exception is not intuitive so we should fix the way we set up LogExporter 
anyway.
