Comments about oreilly Modern Nagios:
These videos strike a great balance between the high level fluff and the sometimes incredibly boring world of text based configuration. The sections on other monitoring solutions and scaling Nagios were incredibly helpful.
Bottom Line Yes, I would recommend this to a friend
