Overview
A low-overhead O/S level event collector that generates events-compatible events. It is designed to run in background, collect times events and channel them (to files, over the network, etc.) It is capable of collecting memory, CPU, etc. usage statistics, as well as WildFly management domain model metrics.

os-stats TODO
- JDG testing
- Network bandwidth statistics, integrate iftop.
- For four CLI metrics (2 for one instance and 2 for another, I get 4 cli.xml warnings. Normally I should get only 2 because I should share the clients.

- Fix logging, get rid of:

- Disconnect the JBossCliMetricSource instances on os-stats shutdown.
- Support for password externalization. Then update Os-stats_Metric_Reference#JBoss_CLI_Metrics with details.
- Warn if the collection time takes so long that it interferes with sampling interval length. Tests.
- Implement os-stats --help metrics that introspects and displays the list of built-in metrics.
- Current OSBase.execute() implementation is naive, implement it correctly.
- Integrate the functionality and get rid of https://github.com/NovaOrdis/shell-tools/blob/master/jboss-os-memory-stats.sh
