I tried to insert our DVA in GW Monitor, using Preferences -> Add Agents ->
Add Agent

The DVA shows up in Monitor, it is correctly recognized as DVA, and platform
and version are correctly displayed (Linux 12.0.2 (3/26/2013) - but Status
is always "Unknown".

It's not a problem of httpusername/password - if I enter this incorrectly,
the Agent does not show up in Monitor.

Access to the Web Console works fine.

Any ideas?
