Does HQ Agent Support HA?

[samana_hyperic]

Hi All,
I am researching the Hyperic HQ HA , I found HQ support server HA by using Clustering HQ Servers.
http://support.hyperic.com/display/EVO/Clustering+HQ+Servers+for+Failover
My question is : Does HQ Agent support HA? For example. There two agent to collect some links's info , one agent may down, but it does not affect the collect data?

You can deploy multiple agents, but they won't behave like a failover solution, it's more like redundancy.

it means HQ agent do not support failover solution, right?
if so, I think I must change my architect to adapt to the agent HA requirement.

No, the Agent does not explictly support failover.
There are several mechanisms to make sure the Agent is running and now collected data is being lost.
As you might know the Agent uses the Java Service Wrapper, which (should) automatically restart the Agent JVM in case it crashes.
It also keeps a backlog of collected metrics in case the network connection to the HQ server is down.
