-------------------------------------

             Summary: Ignite should validate JVM and OS configuration and output warning in log
                 Key: IGNITE-4374
                 URL: https://issues.apache.org/jira/browse/IGNITE-4374
             Project: Ignite
          Issue Type: Improvement
            Reporter: Yakov Zhdanov


Currently we have GridPerformanceSuggestions that output suggestions to logs on Ignite start on how Ignite can be improved.

I suggest to go a little bit deeper and validate more configuration options and add validation for JVM and OS settings.

Ignite should output warning if:
* GC logging is not enabled
* MaxDirectMemorySize is not set (-XX:MaxDirectMemorySize)
* Heap size is greater than 30,5G and JVM cannot use compressed oops
* Any of the recommended OS setting described here https://apacheignite.readme.io/docs/jvm-and-system-tuning are not properly set
