Description

Found this in my own lab. Had a bad ethernet cable but system-plugin was reporting interface as 100% Available.

Steps to reproduce:

1.) Make sure agent is monitoring a network interface
2.) Disconnect network cable (in VCenter, this can be done by unchecking "Connected" for interface)
3.) Watch what system-plugin reports for Network Interface. It will show as 100% Available

Expected Results:

50% Availability reported since interface is still technically up, just not fully Available

Changed Availability for NetworkServer Interface to report 50% if link is unplugged.

Note to QA: While verifying my fix I came across an unusual sigar caching issue with NetIfconfig Flags. It made it appear that my fix wasn't working. I either had to restart the agent or just wait long enough for a new value to be returned by sigar. I'm working on tracking down that bug and will create a different bug report for that and link it to this jira.

validated in hyperic-hqee-installer-4.6.5.BUILD-20120116.100442-15. network interface avaiability decrease when 1 of the network interfaces is down. and is back to 100% when all NICs are connected.
