Over the last several years, I&#x27;ve tried out pretty much all of them.  For smaller environments, the cost of most of the commercial (hosted) monitoring systems is just too damn high. I&#x27;ve currently got a pretty extensive Opsview deployment keeping an eye on everything for me but I&#x27;m about to begin setting up Zabbix to replace it.<p>None of them will do everything you want, so I&#x27;m going with one that will meet 90% of my needs OOTB and will allow me to take care of the other 10% myself.
