Re: [opennms-discuss] A few questions about openNMS.

[Arménio P. <arm...@gm...>]

Hi Gerard,

*1: In which way is the system updated? On event based ( node detects
something, and sends this to the server? (Node ->Server ) OR is the server
polling? ( Server -> Node -> Server )*
I feel tempted to say that it's only by polling, as this is the method I
always used. Somebody will correct me if I'm wrong!

*2: Are open port(s) required ( in the firewall )?*
It depends on your setup. If you only have a firewall between OpenNMS and
its users, then you'll only have to open the Jetty port (8980 by default, if
I correctly recall). If you have a firewall between OpenNMS and its managed
entities, then you need to open ICMP, SNMP and any other service you want to
monitor (SSH, HTTP, JMX, etc..).

*3: Can I install this on several operating systems? Windows, Linux/Unix,
MAC osx?*
I successfully installed and ran OpenNMS in Linux (Ubuntu, Red Hat and
CentOS) and Windows (XP and 7). I've also seen it working on Mac OS X.

*4: Is openNMS capable / able to read out ( homemade / on the fly created (
thru applications ) ) logfiles?*
OpenNMS has a service to handle logs in the syslog format. I think anything
other than that won't be supported.

Good luck!
