Dear all Linux Networking Experts, I am planning to set up a remote monitoring service as Nagios v4 to track my own small VPS. I know how to use this. I have several ebooks about it bought from Packt. I also heard that the new Icinga v2 is faster and less heavy than Nagios v4. However, I cannot find any ebook about Icinga v2. Could you please share your experiences about these 2 monitoring software services?
