Well I can understand the problem but I can't reply in Spanish.
For host NT6729 where applications are greyed out, this is normal .NET agent behaviour, no one is currently using the applications, until they do that, no data is reporting.
For host NT6095, the PerfmonCollectorAgent has a metric clamp, so you either need to reduce the amount of data it reports, or increase the agent metric clamp.
On that machine, again maybe there are no requests at all to the application hosted on that machine.
Otherwise make sure you have run the wilypermissions.exe so that the relevant users under which IIS is running will have the correct permissions to our agent folder.
