I have two Ubuntu (Xubuntu) 14.04 LTS servers. One at my parents' house and one at mine. Ideally I want two things:
- being able to see system information like CPU usage, memory usage and disk usage (and available updates if possible)
- getting an e-mail to my gMail account if CPU or memory usage is too high for too long, or disk space is running low, etc... (I've already configured Postfix with gMail relay so I can send email to my gMail from my machine.)
From what I have seen I have two options: Nagios or Ubuntu Landscape free/personal use and I'm wondering which would suit my needs better?
