edit] Q: How can I use OpenNMS to send pages?

FAQ-Configuration - OpenNMS
OpenNMS already has configurations to use qpage (http://www.qpage.org). You can see them in $OPENNMS_HOME/etc/notificationCommands.xml. I set up users on onms, then setup the users (with the same name) in /etc/qpage.cf. That's pretty much all I had to do in onms. On the qpage side, you need to configure the pager-ids and the service. The key here is that the number used to send alpha pages is not the pager number but a different number talking something called TAP.

edit] Q: How Do I Configure OpenNMS/Tomcat to Use SSL?

FAQ-Configuration - OpenNMS
First create a certificate keystore for tomcat by executing $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA Restart httpd, tomcat and opennms just to be sure and after what seemed too long, I was prompted for user name and password.

edit] Q: What language(s) is OpenNMS written in?

FAQ-About - OpenNMS
OpenNMS is mainly written in Java. The goal for OpenNMS 2.0 is to have a product that will install as a collection of .jar files. icmpd - The 1.4 Java API does not understand ICMP. Since ICMP echo requests ("pings") are the simplest way to test the responsiveness of an IP-based network device, no network management application will be complete without it. The goal is to separate the ICMP functions into their own daemon that OpenNMS will use if present and ignore if not.

edit] Q: How Do I Get OpenNMS to Collect Data from All SNMP Interfaces?

With OpenNMS 0.9, the concept of a "primary" SNMP interface was added to the database. By default the interface with the lowest IP address is designated as the primary interface for SNMP queries. Also by default, performance data is only collected for that interface. If you would like to collect data on all of the interfaces on the node, you need to make a change to the /opt/OpenNMS/etc/datacollection-config.
