I had bad experience with expensive tools in the past, where OS names were listed in the white papers and sales publications, even in the header of scripts, which simply did not work or were a pain to get to work.
Some monitoring solutions can't come out of the box as some demands for applications etc. is far too special so you often have a lot of coding or at least configuration works.
Some companies even charge insane prices for additional probes/modules/plugins/spys (whatever they call them), that are so badly programmed or simple, you could think they are making a bad joke.
I would always setup a detailed Prove of Concept, invite the company and have detailed things tested, before buying anything. The sales often promise a lot, while the techs take the pain or the hotline/support is pushed to the front to block off the customer more or less.
Nagios, as a free tool for example, offers a lot of plugins that cover most things, but the plugins you can get for free are from very good to flawed. Again, sometimes you have to write stuff on your own but can offer them for exchange, if allowed
my 2 cents

1. UNIX for Dummies Questions & Answers
What is the best way to learn UNIX, shell, and Perl on a Windows 2000 machine? My place of employment uses Solaris and Perl and I would like to learn some UNIX skills on my home PC.
I read about "dual boots", "Microsoft Windows Services for UNIX", and "cygwin". What other free options are... (9 Replies)

cf-monitord(8) System Manager's Manual cf-monitord(8) NAME
cf-monitord - cfengine's monitoring agent SYNOPSIS
: cf-monitord [options] DESCRIPTION
: The monitoring agent is a machine-learning, sampling daemon which learns the normal state of the current host and classifies new observa- tions in terms of the patterns formed by previous ones. The data are made available to and read by cf-agent for classification of responses to anomalous states. cfengine is a self-healing configuration and change management based system. You can think of cfengine as a very high level language, much higher level than Perl or shell. Asingle statement is called a promise, and compliance can result in many hundreds of filesbeing created, or the permissions of many hundreds offiles being set. The idea of cfengine is to create a one or more sets of configu- ration files which willclassify and describe the setup of every host in a network. COMMAND LINE OPTIONS
: --help, -h Print the help message --debug, -d Set debugging level 0,1,2,3 --verbose, -v Output verbose information about the behaviour of the agent --dry-run, -n All talk and no action mode - make no changes, only inform of promises not kept --version, -V Output the version of the software --no-lock, -K Ignore system lock --file, -f Specify an alternative input file than the default --inform, -I Print basic information about changes made to the system, i.e. promises repaired --diagnostic, -x Activate internal diagnostics (developers only) --no-fork, -F Run process in foreground, not as a daemon --histograms, -H Ignored for backward compatibility --tcpdump, -T Interface with tcpdump if available to collect data about network AUTHOR
