---------------------------------------
Summary: JVM memory usage metric source
Key: IGNITE-17989
URL: https://issues.apache.org/jira/browse/IGNITE-17989
Project: Ignite
Issue Type: Task
Reporter: Kirill Gusakov
Assignee: Kirill Gusakov
It will be useful to have builtin metric source with jvm memory usage stats.
It must expose the following metrics as a separate gauge metric each:
* heap memory usage (init/used/commited/max)
* non-heap memory usage (init/used/commited/max)
* name of metrics should have the general prefix "jvm." to group all future
jvm metrics together
Also, it needs to check, if calculation of these stats is heavy and we need to
cache it for some time windows.
