1 - Is there a way (anoher utility etc..) which will send me an email notification when the sgminer or cgminer crashes?
2 - Is there a utility which will send me a screenshot let say once per hour on my email? I would like to check whether everthing is running ok etc..
1. There's a software called CGwatcher and as the name implies it monitors your miner to make sure it's working at all times (has options for restarting miner/pc upon given conditions, heat protection, etc).
2. Not that I know of but you can simply download something like TeamViewer which allows you to remotely control a computer (your miner for example). You can install TeamViewer on your work PC or mobile phone and use it to control the miner computer or check on it.
Both CGwatcher and TeamViewer are free.
