Opmantek

Observium

OMD version of Nagios

PRTG ?

Nagios / Icinga / Opsview / other clones / forks – allow the most

customization but maintenance and changing eats quite a bit of one’s

time (at least until the setup is in place)

Observium – nice, user friendly, when you want to have custom checks or

develop more than what the package already provides, then you need to

think a bit if it’s really worth it

Cacti – not really monitoring, albeit you can install a Threshold and

Alerting plugin, plus you do have a nice weathermap
