database - How to "explore" group of servers? -

-

i need check group of servers (unix, linux) know kind of services, software (also version) running there (check once while , store in database). idea have fresh info whole environment - changing. perhaps can suggest solution there?
thinking using nagios or cacti + plugins not sure if solution optimal.

nagios powerful monitoring solution (the best me) : open source, compatible both linux & windows, reporting & notifications via emails/sms, nice interface, many many plugins...etc i've worked & satisfied.

check nico largo's forum install. if not familiar linux command search fan : automated nagios .iso nagios in.

if have trouble during install or configuration post questions there : https://serverfault.com/
