That should be as simple as setting up another Nagios task from a remote server. Of course, if you do not already have such a setup, it might be more convenient.
The poclbm console output still logs RPC errors and "client not connected" messages for solo mining.
Well done. You got lucky today. I will stick to pooled mining. Only a 2% penalty - really not a big deal.
I agree, 2% really isn't a big deal. But the wiki and many forum posts suggest the opposite: that solo mining is less profitable
on average, which isn't true IMHO.
