I'm interested in software used for monitoring network hosts.
Knowledge of system status, things like uptime, hard disk usage,
mem/swap usage, network connectivity are of the upmost importance to
us. It would be great to be able to Administrate a wide range of
servers from a central interface.
We currently use MRTG and some other statistics tools - but they are
prooving to be not comprehensive enough.
I have read about Nagios (www.nagios.org), but it seems to be designed
for a LAN environment - the programs it runs are constantly sending
information to the server. I would prefer something that uses minimal
bandwidth and is designed for testing remote and/or lan hosts, I dont
want to burn bandwidth. Nagios would be perfect otherwise, I realise
there is a parameter which can be set which enforces Nagios to update
less regularly - but due to the fact that it is designed for a LAN
environment, we will never use it.
Thanks in advance for any other suggestions or ideas.
