We are upgrading servers and reloading the client after the upgrade. I am noticing that Hyperic is not noticing the downtime in displaying the uptime or availability metrics. It does notice that the server has went down since it causes me to be paged from Hyperic. I have the collection interval set to one minute. The attached screenshot shows the uptime graph as well at `uptime` from the server. Any ideas why the metrics would be out of sync?
