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