Slides from the Red Hat Summit 2014 session: What's new in JBoss ON 3.2

1. What's new in JBoss Operations
Network
Heiko W. Rupp, Alan Santos, Thomas Segismont
Red Hat

2. Agenda
Overview
New Charts
New Storage Nodes
Finer Bundle Permissions
REST-API
Outlook to JBossON 3.3

3. Overview

4. Let us ask some questions first
Who knows JBoss ON ?
Who uses JBoss ON?
What version?
•3.2
•3.1
•other

5. Did you know?
JBoss ON has an Open Source upstream project called RHQ?
http://jboss.org/rhq
You can reach the developers in
#rhq on
Irc.freenode.net

6. Architecture 100.000 feet

7. Architecture 10.000 feet

8. New charts

9. New charts

10. New charts

11. Storage nodes
Metrics storage scalability

12. Runtime data in JON
•Traits (ex: Platform CPU architecture)
•Events (ex: Error reported in a log file)
•Call-time (ex: Servlet response time)
•Metrics (ex: Swap usage)

13. Metric definitions
•Per resource type
•Some enabled by default

14. Enabling collection

15. Collection process
•Agent plugin collects data
•Sends measurement report to JON server
•Server stores raw values

16. Data usage
•Display in UI (tables and graphs)
•Retrieval through REST API / CLI / Remote API
•Calculate baselines
•Trigger alerts

17. Raw metrics model
•Schedule id ~ Resource id + Metric Definition id
•Data (value collected)
•Time stamp

18. Aggregates
•Retention period: cannot keep data indefinitely
•Storage efficiency at the cost of precision loss
•Raw data -> 1h data
•1h -> 6h
•6h -> 24h 24 hours aggregates
6 hours aggregates 6 hours aggregates
1 hour 1 hour 1 hour 1 hour
Raw Raw Raw Raw Raw Raw Raw Raw

19. Metrics storage before 3.2
•Everything in the relational database
•Simple to access from JON server (@Resource)
•No extra deployment

20. So, what's the problem with metric storage?

21. Consider a large deployment
•3 metrics enabled per resource type on average
•1000 resources per agent
•1000 managed servers
=> 3 million raw data points every 30 seconds

22. Scale-up?
•Top-class hardware
•Top-class database
•... and a top-notch DBA!

23. There must be a better approach

24. Scale-out with NoSQL
•Hybrid model (SQL + NoSQL)
•Incremental approach (only metrics)
•For a fraction of a cost

25. Solution criteria
•Management and support
•Solution needs to be black boxed, self-managed
•Performance and scalability
•No single point of failure
•Support single machine install

26. We created JBoss ON Storage Node
•Based on Cassandra
•Well suited for time series data
•Intensive write loads optimized
•Usual management tools (JMX)

27. User perspective
•'Just' another JON component
•Install with rhqctl
•Add new nodes on demand

28. JBoss ON Server

29. Storage node management
•Agent plugin => requires an agent!
•Auto-imported in inventory
•Dedicated console in the admin pages

30. Simulator
Server Raw Metrics / Minute Heap
Blade Server
iSCSI
2 Storage Nodes
680K 512M per node
Slower due to virtualized
environment
Bare Metal
SSD
2 Storage Nodes
1M 512M per node Higher number of agents

31. Adding a new storage node demo

32. Fine grained bundle permissions
Enabling complex provisioning workflows

33. What is a bundle?
Simply put, a zip file:
•With at least a recipe
•And (optionally) a set of files
010101010
010101010
010101010

34. Files?
•Standalone application
•Web application alone
•Web application, static resources, and configuration files
•Full application server!
•... etc

35. Pluggable provisioning
Out of the box:
•ANT bundles (powerful)
•File template (very basic)
Create your own!

36. Template engine
•Can process any of the bundle files
•@@my.property.to.replace@@
•Built-in variables
•rhq.system.hostname
•rhq.system.cpu.count
•rhq.system.sysprop.line.separator
•... etc

37. Deployment
•To a group of resources (bundle targets)
•From a base location to a destination

38. Old security model
•Global MANAGE_BUNDLE permission
•Create / Delete / Deploy any bundle
•Kept in JON 3.2
•Non critical environments
•Beginners

39. Secure the system with bundle permissions

40. Groups
BUNDLE GROUPS
|
v
RESOURCE GROUPS ---> ROLES <--- USERS
^
|
permissions

41. Permission details
•View (implied)
•Create / Delete
•Assign / Unassign
•Deploy

42. Use cases
•Team leader creates, members deploy
•Team members create and deploy on specific resource group
•Dev team creates, Op team deploys
Flexible enough for your organization

45. REST-API

46. REST-API
Fully supported
•For Output AND Input
•Will be used more (by JBossON) in the future

47. REST-API: External Out-of-Band processing

48. REST-API: External Out-of-Band processing

49. Demo

50. Outlook
● JBoss ON 3.2.CP1
● Coming in JBoss ON 3.3

51. 3.2.CP1
•Bug fix update for 3.2
•Cumulative patch
•Not full release

52. 3.3: Reduced Agent footprint
•Agent uses less heap
•Inventory sync is less costy on the server
•Internal algorithms tuned

53. 3.3 : Better support for EAP 6
•Communication via https
•Bundles and Drift for Domain Mode
•Patching
•Better align JBoss ON groups ↔ EAP groups

54. 3.3 : Integration with Access.redhat.com
•Open cases from within JBoss ON
•Access Knowledge Base
•For JBoss ON
•For Managed EAP

55. Thanks for your attention
