platform resources/metrics
by John Mazzitelli
After a talk with John D. last week, he mentioned we really need some basic platform metrics collected by our wildfly agent. While it is true the agent can collect "some" platform metrics via WildFly like system load average (/core-service=platform-mbean/type=operating-system/:read-attribute(name=system-load-average)) its very limited (in fact, system load average is the only one I found).
So I put together a new pull request to help: https://github.com/hawkular/hawkular-agent/pull/70
This utilizes a third party library Heiko pointed out to me - Oshi (https://github.com/dblock/oshi) - which just does the basics but it has what we want, I believe. It is JNA-based and doesn't require JNI native libraries to be shipped with the product like sigar does. It supports Linux, Windows, and MacOS. It collects basic metrics for four simple resource types - Memory, File Stores (i.e. disks/partitions), Processors, and Power Sources (i.e. batteries).
I have it discovering/inventories those four basic types of resources (along with the parent "OS" resource) and collecting the metrics for them.
The metrics collected are:
A. Memory:
1. Memory Available
2. Memory Total
B. File Stores:
1. Total Disk Space
2. Available Disk Space
C. Processors
1. CPU Usage (this is CPU load between 0% and 100%)
D. Power Sources
1. Remaining Capacity (0% to 100% (fully drained vs. fully charged)
2. Time Remaining (time left before power source is fully drained)
Here's what the inventory looks like (taken from inventory's REST API results):
The top root of the platform resource tree is the "Operating System" resource (Oshi has no metrics per se for the OS resource):

Javascript library for displaying a graph of nodes/links
by Gary Brown
Hi UI devs
I'm looking for guidance on the best JS lib for displaying graphs (i.e. nodes/links) to represent a business process/transaction?
Would need to be able to:
- customise the nodes to represent various types - consumers, producers, components, databases, etc
- annotate nodes/links with information
- capture/act upon actions/events based on node/link selection, offer popup menus, etc.
- colour code nodes/links to highlight different areas of interest
- potentially control link thickness to reflect flows with greater volume of traffic
- collapse/expand certain paths
- ability to scroll around large diagram
- apache licensed
Hoping that we already have a good lib selected for the project to standardise on :)
Regards
Gary
