Hi tbaror,
As far as I'm aware there is no current weather map equivalent.
However you can set up your own custom views and view all platforms in a chart form.
I used to use something similar with nagios, but can't remember what it was.
I think a weather map would be great, however I'm not sure how it would work, I guess it would only be available at a platform level. As I can't see how it could work for Servers and services etc.
Any chance of a platform weather map in Hyperic in the future?
Management love network weather maps!
Regards,
Roger
